An eye with a swollen region of the conjunctiva (front view).

An eye with a swollen region of the conjunctiva (mirror, side view).

Chemosis is the swelling (or edema) of the conjunctiva. It is due to exudation from abnormally permeable capillaries. In general, chemosis is a nonspecific sign of eye irritation. The outer surface covering appears to have fluid in it. The conjunctiva becomes swollen and gelatinous in appearance. Often, the eye area swells so much that the eyes become difficult or impossible to close fully.^[1] Sometimes it may also appear as if the eye ball has slightly moved backwards from the white part of the eye due to the fluid filled in the Conjunctiva all over the eyes except the eye ball.The eye ball is not covered by this fluid and so it appears to be slightly moved inwards. It is usually caused by allergies or viral infections, as well as excessive eye rubbing. Chemosis is also included in the Chandler Classification system of orbital infections. If chemosis has occured due to excessive rubbing of the eye, the first aid to be given is a cold water wash for eyes and use of FluoroMetholone Ophthalmic Suspension USP, commonly known as FML which is an eye drop available in medical stores. Other cases of severe chemosis must be referred to a Medical Practitioner

Other causes of chemosis include:

superior vena cava obstruction, accompanied by facial oedema.
hyperthyroidism, associated with exophthalmos, periorbital puffiness, lid retraction, and lid lag.
cavernous sinus thrombosis, associated with infection of the paranasal sinuses, proptosis, periorbital oedema, retinal haemorrhages, papilledema, extraocular movement abnormalities, and trigeminal nerve sensory loss.
Carotid-cavernous fistula - classic triad of chemosis, pulsatile proptosis, and ocular bruit
cluster headache
trichinellosis
Systemic lupus erythematosus (SLE)
angioedema
Acute glaucoma
Panophthalmitis
Orbital cellulitis
Gonorrheal conjunctivitis
Dacryocystitis
Urticaria

Treatment depends on the cause of the chemosis.
