Eye Diseases in Cats: Symptoms and Treatment, Photo


Eye diseases are quite common among the entire spectrum of cat diseases. The primary goal of helping with any eye problems is to preserve the vision of the pet. The most important thing that the owner of a domestic cat should be able to do is to determine the severity of the damage to the organ of vision, so as not to delay seeking professional help from a veterinary specialist.

Classification of diseases of the organ of vision in cats

Conventionally, all eye diseases in cats are divided into two large groups:

  • diseases and damage to the protective devices of the organ of vision,
  • diseases and injuries of the organ of sight itself (or the eyeball).

To roughly understand the principle of the classification of diseases, it is enough to pay attention to the structure of the cat's organ of vision (see diagram):

The first category of diseases include:

  • bruises and any mechanical damage without compromising the integrity of the skin,
  • wounds and mechanical injuries with skin breaks and bleeding,
  • blepharitis (inflammation of the eyelids),
  • twisting (inversion) of the eyelid (when the free edge of the eyelid is wrapped inward or turned inside out from the eyeball),
  • eyelid fusion (congenital or acquired),
  • lagophthalmos (impossibility of lid information),
  • ptosis (incontinence of the upper eyelid)
  • tumors and various neoplasms.

The second category of diseases include:

  • conjunctivitis,
  • loss of the third century
  • keratitis (corneal pathology),
  • eosinophilic keratitis (corneal lesion with the formation of white plaques),
  • dermoid (benign tumor of the conjunctiva),
  • "Creeping" ulcer (an infection inside the eye due to pathogenic microflora that enters through the inflamed cornea),
  • uveitis (pathology of the vascular system),
  • iritis or iridocyclitis (pathology of the ciliary body and iris),
  • glaucoma (increased pressure inside the eye),
  • cataract (lens opacity),
  • degenerative processes in the retina (dystrophy, atrophy, detachment),
  • dacryocystitis (violation of the patency of the lacrimal canal),
  • loss of the eyeball (exophthalmos),
  • confluence of the eyeball inside (enophthalmos),
  • panophthalmos (very rare purulent inflammation of all membranes of the organ of vision),
  • corneal sequestration (necrosis (dying off) of corneal tissue).

Almost all ocular pathologies (infectious and non-infectious) have a number of similar symptomatic manifestations:

  • lacrimation
  • different kinds of discharge
  • soreness
  • swelling or other changes in appearance,
  • photophobia, etc.

Eye diseases in cats should be treated by a specialist, since only a veterinarian can accurately diagnose and minimize the risk of vision loss in an animal.


Inspection of the animal is carried out in a certain order, which allows not to miss the details or nuances in differentiating the diagnosis:

  • vision assessment of the damaged organ (saved or not),
  • assessment of the overall appearance and comparison of symmetrical features (the size and shape of the pupils, the size of the palpebral fissure, the size and changes in the eyelids, the size of the eyeballs),
  • assessment of the condition of the eyeball (size, shape, injury, location in the pupil).

Bruises and mechanical injuries without compromising integrity

occurs as a result of a blunt-force strike or other mechanical damage (falls, stumbles on non-sharp objects).

  • bruises,
  • hematomas (accumulation of blood clots in the tissues around the eyes),
  • swelling with an increase in local temperature within the injury,
  • changes in the size of the eyeball.

Treatment: will depend on the severity of the damage and you must show the animal to a veterinarian. The eye is washed, with soreness, 2% Novocain, antimicrobial drops or ointments are dropped, it may be necessary to have a cold with hematomas (only on the eyelids, not on the eyeball). In case of complications, surgery is possible with eye removal.

1. Catwalk in cats treatment and symptoms

One of the most common cat diseases. If you notice a turbidity or a white spot - without a doubt, this is a thorn. A cat's gaiter develops due to abnormalities in the cornea (infections or injuries), almost always leading to partial loss of vision. Leukocytes, lipids or proteins can accumulate inside the eye, advanced inflammation and cataracts inevitably lead to an excrement.

Sign of obvious disease, and diagnose the disease is easy. In the central part or on the edge, or on the whole eye, a white or dull spot appears.

Additional symptoms:

- deterioration of vision - it is noticeable that the animal does not see objects,

- strabismus develops (rarely),

- the cat does not allow him to wipe his eyes, hisses and nervous when trying to do it,

- the initial common stage - swelling and redness of the cornea,

- tearing and festering.

2. Glaucoma

The disease is associated with high intraocular pressure. hurts a pet, causes visual impairment, often blindness.

With glaucoma, the cat's eyes are flowing, there is a sensitivity to light, the pupil does not change size in different lighting conditions, the cornea swells, and the eyeball in chronic form is bursting. It is impossible to diagnose glaucoma without a veterinarian, as only he measures the intraocular pressure.

How to treat

- Mannitol (30th droppers) - 1 g per kg of weight. Reduces intraocular pressure.

- Bimatoprost. Eyes drip 2 times a day, 1 drop. If the pupils narrowed, it means that the drug began to act.

- Pilakorpin. 1 drop 1 time per day. Take out the liquid.

- Temolol. Twice a day with an equal interval of 1 drop instilled into the eye.

This therapy usually brings positive results. If the intraocular pressure does not decrease or increases, an operation is indicated.

3. Cataract in cats

The disease is difficult to treat. Leads to blindness.

A cataract is a change in chemical processes in the lens. As a result, the eye becomes cloudy, and the pet loses sight. Without surgery, treatment is not effective. The lens or its part is changing. During rehabilitation, the pet must be protected from sources of bright light, to prevent scratching of the eyes and to prevent injuries, especially headers.

4. Blepharitis in cats

Eye inflammation in cats is associated with blepharitis - when the eyelids are inflamed and the eyes fester. The disease has three forms:

How to recognize blepharitis: eyelids redden, swell, in places of cilia growth gray scales are seen, from which pus flows. Ulcerative blepharitis is a neglected scaly form. Purulent crusts dry up, ulcers form under them. Meybomium - inflammation of the canal (as in barley in humans).

How to help in the presence of this eye disease in cats: eyes should be cleaned of pus with chamomile decoction, the eyelids should be treated with an antibiotic ointment. Detailed treatment is prescribed by a veterinarian after a scraping analysis, as blepharitis causes mites, fungus, allergies. Accordingly, the therapy will be different.

5. Corneal ulcers in cats

Ulcer being treated exclusively with the help of a veterinarian. In no case do not try to treat it yourself - you will lose time and provoke complications. In case of an ulcer, the cornea becomes inflamed, the epithelium dies off and an eye defect is formed. If Murka is squinting, from the eye is flowing, she reacts poorly to light - contact your veterinarian immediately. Excessive eye inflammation in cats can lead to a corneal ulcer. Timely referral to a specialist will help to avoid surgery and preserve the cat's eyesight.

6. Inflammation of the third century in cats

The third eyelid is a film that is visible when the cat is sleeping, but the eyes are slightly open. Often, cats develop a prolapse and inflammation of this century. The disease develops due to problems with internal organs, worms, allergies and eye injuries.

The treatment of the third century in cats consists of washing the eyes of the animal with a decoction of chamomile or olive oil. Also, drops of lacrymine relieve the fluff from pain.

We recommend not treating eye diseases in cats, as the symptoms may be the same and the treatment will be erroneous. Inflammation of the eye in a cat with improper therapy and in advanced stages can lead to loss of vision and surgery. Take care of your pet and contact the vet if you notice that something is wrong with her eyes.

What are eye diseases in cats?

Depending on the place of localization, the disease is divided into two types - the defeat of the eyeball or eyelids. There are quite a few reasons why an animal lost sight, and these are only the most common ones:

Conjunctivitis. Polyetiological inflammatory process on the mucous membrane of the eye. The source of this type of eye disease in cats can be any irritants (trauma, microorganisms, allergies, parasites, unbalanced nutrition). In addition, it can be an additional complication in some diseases. It happens one- or two-way. In the initial stages, it is quickly treated, in later periods it often leads to complete loss of vision,

Keratitis. Described cat eye disease characterized by corneal inflammation. Occurs due to infection or injury. Depending on the severity of the lesion, it is subdivided into superficial or deep types, which can be of several types (fungal, viral, ochocercious, and others),

Cataract. Another common eye disease in cats. Manifested in the form of lens opacification and can be caused by the consequences of purulent keratitis or an infectious disease. There are several types (congenital, traumatic, toxic) and forms (layered, full, capsular),

Blepharitis. This variant of eye disease in cats is characterized by inflammation of the eyelids, thickening of their edges and a rapid transition to the chronic stage. It is difficult to treat, especially in the case of ulcers and abscesses.

Of course, this is not all possible options for eye diseases in cats.

Eye diseases transmitted by cats

On their own cat ophthalmology are not contagious, but it must be remembered that they may be secondary symptoms of more serious ailments. For example, with chlamydia, purulent conjunctivitis is often diagnosed, which facilitates the transfer of infection to humans.

Be aware that eye disease in cats may be contagious to other pets. This is especially true of those species that are caused by parasites, fungi and other infectious pathogens. Naturally you should not be afraid of every feline eye pathology. Many eye diseases in cats are caused by safe reasons: improper care of the animal, injury or an allergic reaction.

Symptoms of eye disease in cats

Despite the long list of eye diseases in cats, the symptoms are much the same. You should pay attention to any change in the character and appearance of the pet:

swelling and redness of the eyelids. Most often accompanied by itching, which is very worried about a pet, who additionally can infect the infection, constantly rubbing his face,

various selections. Regardless of the frequency of manifestation (daily, spring-summer period, after each sleep) and the purity of tearing (transparent, turbid, purulent). Even "morning tears" should be a reason for going to the vet, as they can be one of the indicators of eye disease in cats,

a change in behavior (aggression, lethargy), the absence or painful reaction to light,

any change in the eyeball and lens. Opacification, the presence of film, squint without options indicate eye disease,

physical changes. An increase in the eyeball, the inability to close or open the eyelids, an increase in the third century, tear paths.

Many eye diseases in cats have specific manifestations, but even they are present in the description of any of the above signs. The task of the owner to timely respond to the initial changes.

Treatment of eye diseases in cats

Keep in mind the seriousness of the complications and the similarity of the clinical picture. ophthalmic diseases in cats. That is why it is absolutely not recommended to engage in self-treatment for any manifestation of eye disease.

Only a veterinarian can determine the exact cause and prescribe proper treatment.

Depending on the diagnosis, a four-legged friend may be prescribed: ordinary drops for washing, special eye ointments, it is possible to prescribe antihistamines, antibiotics, immunomodulators. Some eye diseases in cats may require surgery.

Since the diagnosis is sometimes complicated by blurred symptoms or a chronic course of the disease, you should be calm about the possible change of drugs. This is especially true for infectious forms of conjunctivitis caused by fungi or viruses.

It is important to remember that the eye is a fragile organ, and improper intervention can only worsen the manifestations. eye diseases in cats, which in turn can lead to complete loss of vision, in some cases and death.

As a recommendation and preventive measures, only regular hygiene procedures can be advised, which will not only reduce the risk of many forms of the disease, but also promptly notice the beginning symptoms.


Good day! A cat has a swelling of the eyelid of the left eye. Eyes are often narrowed. At first this was the case with the right eye. Everything passed, and now with the left. Can you please tell me what to treat?

Eyelid swelling is one of the symptoms of conjunctivitis or (most likely) blepharitis. Improperly treated blepharitis is the cause of relapses. Treatment should be comprehensive, i.e. antibiotics are not only topical, but also injectable. Ceftriaxone intramuscularly in 1 ml once a day for at least 5 days (preferably up to 7), tetracycline ophthalmic ointment 1% - smear the eye’s cornea 3-5 p / day right after, without fear of pain, for 2 weeks. In the process of blinking the drug will fall under the eyelids where it should be. If the eyes are sour, wash with a decoction of chamomile or just clean boiled water (lukewarm) before each application of the ointment.

Additionally, it is not bad to add immunomodulators (immunofan, cycloferon, gamavit - according to the instructions), since blepharitis often occurs against the background of a decrease in the overall body resistance.

After a course of treatment with an eye ointment, it will be necessary to revise the eyes and the body as a whole to exclude eye injuries, fungal and parasitic skin lesions (especially on the head), which may require additional treatment.

Hello! Help, please, cat had a fight, hurt the eyes. I can not understand, it seems that the eye is visible, but a small discharge of pus from the eye, and the worst thing that climbs out something like a sac, does not allow to touch it. Washed decoction of chamomile, put into the tetracycline ointment, gave an antibiotic, because the temperature was 40, it has now dropped, stuck out the tip of the tongue, does not eat or drink anything. What to do?

Hello! As a matter of urgency, to show the cat to the veterinarian - it is imperative to conduct an audit of the injury, which may require an introduction to anesthesia. If a panophthalmos begins, then you are not that eyesight, you will not even save the eye, you will have to delete it! (approx .: Panoftalm is a purulent lesion of all layers of eye tissue, the most serious complication of penetrating wounds of the eyeball)

under the eye of a cat dot black

Hello) the kitten in the pupil of some kind of light fabric. It looks like a crack in the glass, like a little star. When the pupil is narrowed, the asterisk also shrinks. There was no injury, no tearing of the eye, normal shape, no mowing. What could it be? Does it affect vision? Will it progress?

Hello! Show the kitten to the specialist - in-person consultation is required. There may be a violation of the pupil pigmentation, and a cataract, and an eye injury (you might not have noticed how the animal struck) and anything. Only after making a diagnosis can we say what the prognosis is and what the animal is waiting for ahead.

Hello, I took a kitten to him 1 month old, a half Turkish breed hangar. The eyes are chasing and for some reason the ears are constantly dirty, my savewig soap like abundant discharge ended, but still remained especially after a dream. What to do?

Hello! I did not quite understand that you were washing with soap. Eyes. Let go of soap, soap categorically can not wash the eyes. Rinse with chamomile broth, strained through a cotton pad, and then drip chloramphenicol drops (1 drop up to 5 times a day for 10-14 days) into the eyes or smear it with tetracycline ophthalmic ointment 1% right through the cornea (also up to 5 times day for 10-14 days). The course of antibiotic therapy cannot be stopped at the first signs of relief, it is necessary to finish the indicated time.

In the ears, most likely, ear mite, but for more accurate diagnosis, show your veterinarian. And yet - you need to measure the temperature, because eye problems may accompany some infectious diseases (this will show a fever), and these are completely different treatment regimens.

Hello! Kotu is 15 years old, from time to time there is blood in one eye or another. The cat does not walk on the street, did not get injured. A few days ago, noticed that he almost did not see. What can it be and can it, at least partially, return sight? Thank you in advance! Appealed to the veterinarian, said need to an ophthalmologist. Но пока назначили уколы актовегина и капли в глаза эмоксипин и тауфон.

Hello! I didn’t quite understand where exactly the blood appeared - inside the eye chamber or maybe coming from the lacrimal canal? To say whether it is possible to return sight, it is necessary to determine the exact cause of its decline. In this case, alas, it is very difficult to say without inspection. Try to still find a veterinarian ophthalmologist. The appointment is correct, covering all possible causes of visual impairment. One thing I can say for sure - if the degenerative changes in the eyes are associated with age-related changes in the body, then alas, it will not work to return the vision.

Hello! The cat periodically reddens the cut of the eye, when it appears, it blinks this eye, there is no swelling and tears. Always washed with strong tea leaves, passed. What to do to completely this no longer appear?

Hello! Just a few words about the various brews, teas, daisies, etc. - to wash with all these solutions is possible only after deep filtration through 1-2 cotton wool disks. The bottom line is that the solutions themselves act positively on the state of the mucous membrane, but then micro-particles of sediment remain on the surface of the eye, which then again trigger the inflammatory process.

What you need to do: ideally show the animal to the veterinarian so that he carefully looks at the eye for foreign objects, eyelids or dermoids. If not, then the procedure is standard: we wash both eyes with ordinary boiled water or a pharmacy saline, and then drop 1-2 drops 4-5 times a day with ordinary eye drops: levomycetin eye (human) or Levomekol (veterinary). General course - at least 10 days. It is necessary to remove the hidden infection once and for all, and not to remove the symptoms.

Good day! Help me please. I have 2 cats. Both gave birth to kittens. One cat suddenly began to appear bald spots behind the ears and the loss of the third century as in your photo. The kittens began to sour eyes. Washed kittens furatsilinom, everything went. They did not have time to take the cat to the doctor, we live in a private house, the cat went for a walk and disappeared. Kittens fed another cat. Now the second cat started the same with the eyes, but behind the ears so far only a small speck without hair. The cat squints eyes, 3 eyelids are very visible. One kitten had a swollen eye and closed. A cat and a kitten were taken to the doctor, she said to give them azithromycin and that's it. Tell me is it true?

Hello! On the face of some kind of chronic infection, which directly "mows down" all the cats. And the bald patches behind the ears can be associated with many reasons: a paw is rubbing against the background of a disease of the ears, a fungus, versicolor, a subcutaneous mite, etc. - here it is necessary that the veterinarian conduct an inspection.

Without topical eye treatment, azithromycin will not give anything inside. By the way, it is better to give tetracycline inwards - if suddenly it is chlamydia, which is very similar, then it is the antibiotics of the tetracycline series that take it. The loss of the 3rd century occurs just against the background of strong infections. In the eyes you need to drip antimicrobial drops. And absolutely everyone and in all eyes, regardless of whether there are visible lesions or not. After washing the eyes with the same furatsilinom, drip in the eye drops with chloramphenicol (veterinary, which you will find - with him). The first day drip hourly, then every 2-3 hours, then 4 times a day, then 3 times a day and up to 14 days a course. At the end of the course of treatment, animals should be shown to the veterinarian in order to exclude a 3rd-century adenoma and it would be nice to pass a smear for chlamydia. If you are not lazy to drip as it should be, everything with eyes will be fine.

Hello! A cat 5 years old, a couple of months ago a small dark brown speck appeared on the outside of the iris, it seemed to have slightly increased in a couple of months. Kotu does not cause inconvenience, there are no other "bad" signs, eating, drinking, running as usual. What could it be? thank

Hello! It is difficult to say without inspection. I suppose that this nevus is a pinch of pigment or, in other words, the same birthmark, but on the iris. It may be innate, may appear on the background of some hormonal changes. It is necessary to see a veterinarian if the “birthmark” begins to increase sharply or some other symptoms of ill health appear in the eye.

Hello! Kotu is 5 years old. A week ago, a granddaughter (4 years old) cut a cat's mustache. They read that the cat is now stressful, the cat is not eating well, and now there are brown spots on the bottom of the right eye on the iris. What can it be and what to do? Thanks a lot in advance.

Good day. picked up an adult cat (age-year and a half) from the street, with kittens ... color - balinese, bright blue eyes. Kittens fed. The cat was sterilized. the color of the iris began to change from blue to yellow, but only one eye. No turbidity, no belmuses. What could it be? thank you in advance

Hello! I would recommend to show the cat to the ophthalmologist. Ophthalmology is a complex science, without an inspection to make a diagnosis, alas, it will not work. An uneven change in eye color in an adult animal over a short period of time is usually a sign of a bacterial or viral pathology. Most often this happens with uveitis (internal inflammation of the eyeball) or, for example, with VIC (viral immunodeficiency of cats). However, simply a genetically determined violation of the pigmentation of the eye is also not excluded. Without inspection it is very difficult to identify something specific. Better reinsure your vet clinic.

Hello, at the small kitten, the eye began to grow turbid and the eyeball has increased, it seems that the eye may fall out, what could it be? What to treat?

Hello! Very similar to the inflammation of the eyeball. But with blurred and ambiguous symptoms, when the exact diagnosis cannot be made according to the description, it is dangerous to prescribe the treatment. Show the kitten, if possible, to a specialist and the sooner the better, because there is a risk of losing an eye.

Hello! At the cat (8 years old) the white film in the corner of the eye became visible, the third eyelid, as I understood from the article, after washing the eyes, it became smaller, but it hasn’t disappeared anywhere for about a week. Simultaneously with the film, diarrhea appeared, coal was given, everything went away, but for the last two days the nose was always warm or hot ... It doesn't seem to hurt, but it became more sleepy. We get to the vet only in a week. What can it be and what can be done so far?

Hello! This condition of the eye is accompanied by some infections of cats - viral or bacterial. The veterinarian will determine the type of infection during the examination (it is disastrous that you will get to him only in a week).

The animal becomes sluggish, indifferent and more sleep usually with increasing body temperature. At home, you can only measure the temperature, and, if it is above 39 degrees, give the animal antipyretic (tolfined, loksikom - strictly according to the instructions for the drug). I have no moral right to appoint anything else without inspection.

As for the third century. Prolonged, untreated inflammation can lead to a third-century adenoma, so antimicrobial eye drops are also required in addition to washing. Get to start chloramphenicol eye drops (in a veterinary pharmacy, preferably) and bury in each eye for 1 drop the first day every hour, for the second - up to 7 times, for the third and then up to 10 days - 2-3 times a day. Be sure to inform the veterinarian about this when you go on an appointment so that he will make the necessary adjustments to the treatment if the situation requires it after an examination.

Hello, tell me please ... We have a Persian cat, he is already 18 years old. 2 years ago, a lump filled with blood (like a bag) came out of his right eye. She did not deliver any discomfort to him, but just 2 months ago, these bumps began to grow further. There are already 3 of them on the right eye, and one has already appeared on the left. We are afraid to take him to the ophthalmologist, the cat is old, and he endures all movements extremely badly ...

Hello! They took a stray cat in people with overexposure. Her eye was injured, a drop was said to drop, and the eye would stop watering, but it always got watery. Can her tear channel be damaged? Or do we drip infinitely?

Hello, my Siamese cat has severe exhaustion, but eats well, recently could not walk, staggered, wrote injections to vitam and glucose, lactoferon tablets, walked better, after a couple of days the eyes began to twitch like a "pendulum". Tell me what's wrong with her, I already thought of ataxy?

A three-color cat leaks one eye, with bloody discharge ...

Hello my
the cat had a fight, one eye began to water, it did not bleed, the eyeball was white. A few days later began to sneeze, appetite is normal. Tell me how to treat

Good evening, please tell me. Cats 13 years ago became sluggish a couple of days ago refused to eat, they noticed red spilled spots in their eyes. Today they brought them to the vet there they said that the detachment of the iris and nothing was done. I am very upset, maybe there are still some lectures.

Hello, I have a cat and a cat. When they took the cat, he sneezed, the cat began to sneeze. Now they have something with eyes, it doesn't look like pus, some kind of pink or brownish mucus. Every day I clean it with a tampon dipped in furatsilina solution, I tried to dig in the drops of levomycetin drops, but it does not work. and they still breathe noisily, put injections for immunity, they advised me in the vet pharmacy, but there is no point.


Conjunctivitis is a common disease. This is an inflammation of the mucous membrane of the eye in cats. The nature of conjunctivitis is bacterial. Infection occurs when infection in the upper respiratory tract.


Conjunctivitis can be 4 forms:


Allergic conjunctivitis is caused by the body’s response to an allergen. The first symptom of this disease is profuse tearing.

If the disease does not begin to heal, then other symptoms will appear:

  • purulent and bloody effusions (have an unpleasant smell),
  • loss of the third century
  • purulent accumulations of various shapes in the eyes,

First you need to identify the allergen. Treatment is prescribed after the cessation of contact with a specific allergen. For the treatment using antihistamines.

Parenchymal (phlegmonous) conjunctivitis

A characteristic symptom is inflammation of the subconjunctival fiber.

Other symptoms:

  • discharge of pus and blood
  • inflammation of the eyelids.

Treatment must begin at the first symptoms. Because this disease can lead to blindness.

Follicular conjunctivitis

This is a chronic form of conjunctivitis. She is difficult to treat.


  • - fear of light,
  • outflow of purulent fluid from the eyes,
  • inflamed follicles.

How to treat? The therapist prescribes maintenance therapy and special ointments. If necessary, use antibiotics.

Keratitis is inflammation of the cornea of ​​the eye. Often short-haired and hairless cats are infected.


The reasons for the development are different:

  • mechanical effect (the most common cause),
  • genetic reasons
  • malnutrition,
  • blockage of lacrimal glands,
  • eye burns
  • allergies of various forms,
  • infectious diseases.

Symptoms of keratitis in cats:

  1. The painful sensitivity of the eye to light (photophobia).
  2. Scarring. If this symptom occurs, blindness may occur.
  3. Fluid leakage from the eyes.
  4. The accumulation of infiltration (cellular elements with an admixture of lymph and blood).
  5. Germination of blood vessels in the cornea of ​​the eye.
  6. Blurred cornea.

If keratitis is not treated, then complications can appear:

  • Loss of vision
  • Glaucoma
  • Breakthrough cornea eyes.
  • Cataract.

Keratitis should be treated by a veterinarian. If possible, eliminate the cause. After elimination of the cause, medications are prescribed (antimicrobial, hormonal, with antibiotics). If necessary, use special serum. Long term treatments are effective.

Third eyelid

The third eyelid is the functional and protective structure of the auxiliary apparatus of the eye. It connects the lower and upper eyelids.

Third eyelid

A blinking membrane rubs the eye to remove specks and dust. The flashing membrane in its normal state is barely noticeable. It can be seen only with a fallout.

The loss of the third century occurs for such reasons:

  • CNS damage,
  • infectious and internal diseases,
  • conjunctivitis,
  • mechanical impact or ingress of a foreign body.

Symptoms of a blinking membrane:

  • lacrimation
  • redness,
  • pet rubbing face paw.

For the treatment of a blinking membrane, it is necessary to determine the cause. This can only be done by a qualified veterinarian. For the diagnosis used ultrasound, examination and analysis. For prevention it is recommended to carry out medical examination.

Blepharitis is a group of eye diseases. Blepharitis is manifested as inflammation of the lid margin. The disease is characterized by a chronic course.


Blepharitis is not a serious disease, but treatment requires an integrated approach.

The reasons may be different:

  • autoimmune diseases
  • allergy,
  • disruption of the endocrine system or sebaceous glands,
  • pathogens,
  • mechanical injury
  • parasitic invasion (cat infection with parasitic worms).

There are several forms of blepharitis:

  1. Meybomium. Characterized by the formation of formations at the edge of the century. There is a high level of secretion.
  2. Ulcerative blepharitis. Leaks with the formation of yellowish crusts. Often the cause of this disease is chronic infection. Various symptoms (fatigue, photosensitivity, lacrimation, etc.) may occur.
  3. Scaled blepharitis. This form is characterized by the following symptoms: thickening of the eyelids, redness. Often the cause of scaly blepharitis is Staphylococcus aureus.

Treatment is carried out under the supervision of a qualified veterinarian.

After elimination of the cause, complex treatment is prescribed:

  • immunoglobulin course,
  • antibiotic course
  • antibacterial emulsions and suspensions.


Panophthalmitis is an inflammation of the eyeball and tissues.



  • hematogenous drift of infection,
  • introduction of infection in case of eye damage.

Symptoms of panophthalmitis:

  • reduction of visual function
  • corneal clouding,
  • chemosis,
  • swelling of the eyeball,
  • blepharospasm
  • photophobia.

Panophthalmitis is of two forms:

  1. Endogenous panophthalmitis.
  2. Exogenous panophthalmitis.

Antibiotics and sulfa drugs are used to treat panophthalmitis.

Cataract is a common eye disease. The disease is accompanied by loss of visual acuity. A characteristic sign of cataract is clouding of the lens.


The main cause of cataracts in cats - a violation of the exchange process. And also the pathology can be acquired or congenital (surgery on the eyes, diseases, inflammatory processes in the tissues). Often cataracts are found in adult cats.

Cataract is divided into two forms:

The acquired form is divided into the following types:

  • senile
  • toxic,
  • diabetic,
  • symptomatic,
  • hormonal,
  • traumatic.

Symptoms of cataracts:

  • blurred vision
  • pupil opacification
  • malaise.

Inflammation of the nasal duct

Canaliculitis is an inflammation of the nasolacrimal canaliculi. Canaliculitis is a secondary process.

Inflammation of the nasal duct

As a rule, it occurs on the background of any inflammatory diseases of the eyelids:

Characteristic symptoms of inflammation of the nasolacrimal canaliculi:

  • discharge of pus from tear points,
  • hyperemia,
  • redness and swelling,
  • pain in the affected area
  • lacrimation.

Conservative or surgical treatment is used.

Eyelid wounds are a common cause of going to a veterinarian. There are stab, ragged and incised wounds. Wounds can be without damage or with damage to the free edge. Often the wound of the eyelid is accompanied by subcutaneous hemorrhages and hyperemia of the skin.

Century wounds

Such damage occurs as a result of injury to the teeth and claws of animals.

Symptoms of eyelid injuries:

  • exudate excretion
  • inflammatory edema
  • soreness in the wound area
  • bleeding.

The wounds of the eyelids are divided into the following types:

Wound treatment:

  • mechanical wound cleansing
  • lubrication of the skin with a special solution (alcohol, green),
  • if necessary, adjust the bandage.

For the treatment of deep wounds, you should contact your veterinarian.

Inversion of the century

Inversion of the century (entropion) - eye disease. Entropion is accompanied by turning the ciliary edge of the eyelid to the eyeball. Wrapped eyelid and eyelashes may be subject to mechanical stress. This often leads to eye damage and vision loss.

Inversion of the century

Some breeds of cats are prone to torsion of the century:

Symptoms of eyelid turn:

  • wet skin and hair of the lower eyelid,
