Chemosis is the swelling (or edema) of the conjunctiva. 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.[1] It is usually caused by allergies or viral infections, as well as eye rubbing. Chemosis is also included in the Chandler Classification system of orbital infections.[citation needed]
Other causes of chemosis include:
- superior vena cava obstruction, accompanied by facial edema.
- hyperthyroidism, associated with Exophthalmos, periorbital puffiness, lid retraction, and lid lag.
- cavernous sinus thrombosis, associated with infection of the paranasal sinuses, proptosis, periorbital edema, retinal hemorrhages, papilledema, extraocular movement abnormalities, and trigeminal nerve sensory loss.
- cluster headache
- trichinellosis
- systemic lupus erythematosus, SLE
Treatment depends on the cause of the chemosis.
