Common cat eye conditions
Conjunctivitis is an inflammation of the membrane that covers the inner lining of the eyelids. This inflammation may extend to involve the white of the eye. It may be caused by allergies or by bacterial, fungal or viral infections. In fact, recurrent or chronic conjunctivitis in cats is often the result of herpes viral infections which can return - again and again. It can be contagious, so keep an infected cat away from others.
Corneal Ulceration can occur when the shiny surface of the cornea is scratched or damaged. Again erosion and ulceration, also known as a keratitis, can be associated with a herpesvirus infection of the cornea.
Epiphora occurs if your cat's eyes constantly "weep",due to an increased tear production or the normal tear flow through the tear duct is blocked. The fur around the eyes becomes "stained"due to the constant wetting effect which is often the sign that owners notice more often as a consequence of the problem.
Cataracts. Cats, just like humans, can have these serious eye diseases. Cataracts, which cloud the lens inside the eye can sometimes be seen in elderly cats. A thorough evaluation by your veterinary surgeon is necessary as surgery is the only treatment.
Glaucoma stems from too much pressure being exerted upon the eye's interior as a result of a decrease in the amount of fluid draining from it. This increased pressure can damage the sensitive retina inside the eye which can lead to blindness.
