What is conjunctivitis?
Conjunctivitis is the medical term that describes an inflammation of the conjunctiva, the thin membrane that covers the white of your eyes (sclera). This membrane produces mucus to coat and lubricate the surface of the eye. When the conjunctiva becomes irritated, the blood vessels enlarge making the eye appear red in color. The three common types of conjunctivitis are: viral, allergic and bacterial.
The conjunctiva is a mucous membrane, similar to that of the mouth and nose, that surrounds the eyeball forming a seal with the inner surface of the eyelids. The third eyelid is also covered by conjunctiva. In normal cats the conjunctiva is not readily visible and has a pale, salmon pink color. Conjunctivitis is an inflammation of this membrane which becomes swollen and reddened often making it more visible. Conjunctivitis can affect one (unilateral) or both (bilateral) eyes. How do I know if my cat has conjunctivitis? Cats with conjunctivitis tend to have a discharge from their eye(s) which can be clear or thick and purulent. The conjunctiva is often more visible and reddened particular in the corner of the eye and can be swollen, partially covering the eye. Frequently the eye(s) are held half closed and the third eyelid is more prominent. What are the causes of conjunctivitis? A number of different conditions will cause conjunctivitis, many are sudden in onset and easily treatable ot
