Chemosis
Chemosis
Chemosis (/kɪˈmoʊsɪs/ ki-MOH-sis) is a medical condition that involves swelling of the conjunctiva in the eye. The conjunctiva is a clear mucous membrane that lines the inside of the eyelids and covers the white part of the eye, or the sclera.
Etymology
The term "chemosis" is derived from the Greek word "kheimo" which means "to pour", and "osis" which is a common ending in medical terminology indicating a condition or state. Thus, chemosis refers to a state where fluid has poured into the conjunctiva, causing it to swell.
Symptoms
Symptoms of chemosis can include redness, irritation, and a sensation of a foreign body in the eye. In severe cases, the swelling can be significant enough to prevent the eyelids from closing properly.
Causes
Chemosis can be caused by a variety of factors, including allergies, infections, inflammation, and trauma to the eye. It can also occur as a side effect of surgery on the eye.
Treatment
Treatment for chemosis typically involves addressing the underlying cause of the swelling. This can include the use of antihistamines for allergies, antibiotics for infections, or steroids to reduce inflammation. In some cases, surgical intervention may be necessary to drain excess fluid from the conjunctiva.
