What is chemosis

Swelling (edema) forms in the conjunctiva, the mucous membrane coating of eye (conjunctiva is not present on the cornea). It can cause irritation, a foreign body sensation, and in severe cases the eyelids may not be able to close fully, leading to more ocular surface dryness and irritation. Severe conjunctival swelling may push the eyelid downward and away from the surface of the eye.
