Eyelid diseases

From Cat

The upper and lower eyelids should lie in close apposition to the cornea and within the palpebral fissure there is very little exposed conjunctiva except for a small portion of third eyelid conjunctiva at the medial canthus and sometimes, a small area of bulbar conjunctiva laterally[1].

Adult cats blink infrequently, a complete blink takes place about once every 5 minutes and incomplete blinks are rare. As in humans, the upper eyelid is more mobile than the lower. A common sequela of eyelid disease is eyelid inflammation (blepharitis).
