Breed problems Diabetes Feline leukocyte antigen DRB restricted polymorphism Flat-chested kittens Glaucoma - tendency to primary narrow-angle glaucoma Hypokalaemic myopathy Keratoconjunctivitis sicca (KCS), also called "dry eye", is a disease resulting from a decrease in the aqueous component of your pet’s tears. This component is produced by the lacrimal gland and gland of the third eyelid. Tears function to provide lubrication to the surfaces of the eye, nutrition to the cornea, help protect against bacterial overgrowth, flush debris from the eye, and maintain an optically smooth surface for clear vision. When there is a deficiency in tear production, the surface of the eye becomes dry, causing discomfort and irritation. Chronic irritation of the corneal surface can create abnormal pigment changes, blood vessel growth, and scarring all of which can lead to vision loss. The corneal is also at risk of ulceration (a wound on the surface of the eye). The eye may also collect debris, and is at risk for bacterial overgrowth leading to infection of the conjunctiva or cornea. KCS occurs less commonly in cats with the Burmese being the most common breed recognized. It may also occur secondary to chronic feline herpes virus infection. This page was last edited 03/27/08
