chemosis
Pronunciation: kee-MOH-sis
Swelling of the conjunctiva, often appearing as a fluid-filled blister around the cornea.
Full Definition
Chemosis refers to edematous swelling of the bulbar and/or palpebral conjunctiva, creating a characteristic 'jelly-like' appearance around the eye. This condition can result from allergic reactions, infections, inflammatory processes, or surgical trauma. In the perioperative setting, chemosis may develop following certain surgical procedures, particularly those involving significant manipulation of conjunctival tissues. While often self-limiting, severe chemosis can interfere with eyelid closure and require treatment with topical lubricants, anti-inflammatory medications, or drainage procedures.
Usage
Usage note: Often described with qualifiers such as 'mild,' 'moderate,' or 'severe' to indicate degree.
