Diseases Of The Eyes In Cats


Diseases of the eyes in cats are very common and significantly reduce their quality of life. Eye diseases of cats should be treated only by a specialist - a veterinarian ophthalmologist.

Very often, an eye symptom can indicate serious health problems of the pet: for example, diabetes mellitus, conditions that occur with an increase in pressure, will have characteristic symptoms from the side of the eye apparatus.

The cat is a territorial animal, a crepuscular predator. Dexterous, fast, perfectly coordinated, she needs keen eyesight.

The cat's eye is a very complex organ, the specific anatomy of which allows the animal to see with minimal light. The eyes of cats are large relative to the muzzle, they give an overview not only in front of them, but also around the periphery. Cats see better at a distance of 6-7 meters than up close, so they often observe what is happening around them from tall objects.

Some cat breeds can have huge and bulging eyes. In addition, there are breeds that have no or almost no eyelashes, which means their eyes are defenseless. There are cats of a raw constitution, their eyelids do not fit tightly to the eyeball, and this also entails additional risks of injury and foreign bodies.

Respiratory diseases of cats often occur with symptoms of conjunctivitis, and infectious eye diseases are more common in kittens.

Thus, eye diseases in cats are very common, they can have an exogenous cause - infectious or traumatic, or endogenous - associated with the pathological state of organs or body systems.


The conjunctiva is thin, normally a transparent tissue lining the eyelids from the inside and the eyeball from the outside. Its inflammation is called conjunctivitis. Such a process arises in response to:

*Trauma (scratching with the claw of another cat, self-injury, ingress of a foreign object (sand, wood chips, plant seeds);

*Development of infection (rhinotracheitis, calicivirus, chlamydia, mycoplasmosis);

*Chemical exposure (contact burns of the conjunctiva or exposure to vapors of certain chemicals can lead to conjunctivitis);

*Autoimmune process;

*Pathology of the structure of the eye (volvulus, eversion of the eyelids).

Conjunctivitis is manifested by edema (swelling) of the eyes, hyperemia (redness), lacrimation, such an eye will surely hurt. There will be traces of discharge around the eyes, the wool is glued together.

Treatment of conjunctivitis implies at the first stage an accurate diagnosis, and only after the doctor knows exactly what caused the inflammation, he will be able to give precise recommendations on what to do. Conjunctivitis is treated with local agents (drops, ointments, gels containing antibiotics, non-steroidal anti-inflammatory, hormonal drugs) and systemic drugs (tablets, injections).


Blepharitis is a cat eye disease that occurs with inflammation of the tissues of the eyelid margins.

This process, like conjunctivitis, can be caused by trauma, infection, an autoimmune process, and chemical exposure. But other than that, blepharitis can also look just like red eyelids. The reasons may be:

* Parasitosis (microscopic mites such as Notoedros cati and Demodex cati);

* Inflammation of the meibomian glands.

Blepharitis symptoms are red, painful, inflamed eyelids, and itching. Often crusts, sores are formed, such eyelids will hurt, the cat will scratch them, thereby aggravating the problem. There will be traces of discharge around the eyes.

In the clinic, to establish the cause of blepharitis, they will conduct an examination, they will probably take scrapings for parasitosis, smears for infections, treatment will be prescribed based on the results of the examination. Before an accurate diagnosis is made, the edges of the eyelids are sanitized, the eyes are washed with antiseptic solutions (or special eye lotions), and an Elizabethan collar is worn so that the cat does not scratch the eyes even more.

It is important to remember that if a cat's eye is inflamed and you notice that the problem looks exactly like "red eyelids", then it is likely that it is not local, ocular, but systemic, and the doctor will have to be especially careful when making a diagnosis.

Most often, itchy mites (notoedrosis and demodicosis), leading to eye diseases, occur in cats walking on the street.

Prevention - compliance with zootechnical standards for keeping animals, terms of vaccination and antiparasitic treatments, territory management, exclusion from breeding of animals with pathological anatomy of the eyelids.


Glaucoma is a dangerous eye disease in cats, in which the main symptoms are an increase in the volume of the eyeball, its clouding, tearing, reddening of the eye tissues, decreased vision, severe discomfort for the animal.

What actually happens when we notice that the cat has “swollen eyes”? The fact is that there is a constantly renewable fluid inside the eye. And it is the balance of its replenishment and outflow that makes it possible to maintain a certain intraocular pressure. There are a lot of reasons for this violation, among them:

*Congenital anomalies

*Injuries (eye contusions, penetrating wounds);

*Uveitis (inflammation of the choroid of the eye);

*Luxation (displacement) of the lens;


*Neoplasm (tumor).

The diagnosis and treatment of cataracts should be dealt with only by a veterinarian with a narrow specialization - an ophthalmologist. On examination, he first of all must determine the pressure in the cat, then tonometry is carried out - the intraocular pressure is determined. Next, gonioscopy takes place - the doctor determines how the intraocular fluid outflow system works. Followed by ophthalmoscopy (direct and indirect) is an examination of the fundus, as well as other structures within the organs of vision.

Treatment of glaucoma with drugs can be effective only in the early stages of the disease, but if the process is neglected, then, unfortunately, it will almost certainly be about removing the eye. This measure will allow the animal to avoid chronic pain and inflammation, because such an eye will hurt all its life. If the aesthetic component is important for the owner, then prosthetics of the cat's eyeball is possible.


Keratitis is an eye disease in cats with corneal inflammation. In essence, the cornea is a lens, the main function of which is to work with light, without which the cat cannot see.

*Keratitis occurs due to:

*Congenital anomalies;

*Injuries (eye contusions, penetrating wounds);

*Uveitis (inflammation of the choroid);

*Luxation (displacement) of the lens;


-Keratitis symptoms:


*Blepharospasm (the eye is constantly squinted);

*Swelling of the eye;

*Clouding of the cornea (it becomes dull, not shiny, as before the disease);

*Vessels are visible in the eye;

*Exudation (tears around the eyes, and later mucus and pus)

Diagnosis of the disease is carried out by a veterinarian-ophthalmologist. Specific diagnostic techniques are as follows:

1-Biomicroscopy of the eye

2- Bacterioscopic examination

3- A test with fluorescein (a special dye is instilled into the eye, injuries and ruptures of the cornea are stained).
