Chemosis is swelling of the tissue that lines the eyelids and surface of the eye (conjunctiva).
Fluid-filled conjunctiva; Swollen eye or conjunctiva
- Allergic response
- Viral infection (conjunctivitis)
Over-the-counter antihistamines and cool clothes placed on the eyes may help relieve symptoms due to angioedema or allergies.
If symptoms continue, see your doctor.
Call your doctor if your symptoms do not go away. Also call if you have other symptoms such as eye pain, change in vision, difficulty breathing, or fainting.
The doctor will perform a physical exam and ask questions about your symptoms, which may include:
- When did it start?
- How long does the swelling last?
- How bad is the swelling?
- How much is the eye swollen?
- What, if anything, makes it better or worse?
- What other symptoms do you have? (For example, breathing problems)
Your doctor may prescribe an eye cream to reduce swelling. If the swelling is caused by an infection, antibiotics will be given.
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.
