Chemosis - Overview

Alternative Names

Fluid-filled conjunctiva; Swollen eye or conjunctiva

Definition of Chemosis:

Chemosis is swelling of the tissue that lines the eyelids and surface of the eye (conjunctiva).

Considerations:

In general, chemosis is a nonspecific sign of eye irritation. The outer surface covering appears to have fluid in it. Often, the eye area swells so much that you can't close your eyes properly.

Chemosis is often related to an allergic response or infection.

Common Causes:

Angioedema
Allergic response
Viral infection (conjunctivitis)
