Chemosis

Overview Treatment

Chemosis

Definition:

Chemosis is a condition in which the membranes that line the eyelids and surface of the eye (conjunctiva) are swollen. The outer surface covering appears to have fluid in it. Often, the conjunctiva become so swollen that the eyes cannot close properly.

Alternative Names:
Fluid-filled conjunctiva; Swollen eye or conjunctiva

Considerations:

In general, chemosis is a nonspecific sign of eye irritation. Accumulation of fluid in the surface membranes causes them to swell. This symptom is often related to an allergic response, infection, or severe exposure.

Common Causes:

• Angioedema
• Allergic response
• Viral infection (conjunctivitis)
• Exposure such as sleeping with eyes open
