Chemosis

• Overview
• Treatment

Definition:

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

Alternative Names:

Fluid-filled conjunctiva; Swollen eye or 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)
