What is Chemosis and how is it related to eyelid surgery?

Chemosis is the swelling of the white part of your eyeball that surrounds the pupil (dark part in the center). It usually happens to a mild degree after lower eyelid surgery and resolves within a few weeks. It can however last for months in some cases. In my opinion it is related to the extensive dissection and trauma of surgery. A find technique with minimal dissection can minimize the chances of chemosis.

Chemosis refers to swelling of the conjunctiva which is the covering that lines the eyelid and drapes over the front of the eye. The conjunctiva that we see is clear and the tissues underneath it are white. There can be a number of reasons that the conjunctiva swells so chemosis does not tell one anything about the cause of the swelling. However, following surgery, the eyelids swell and yes the conjunctiva can and does also swell.
Normally after surgery, the swelling of the conjunctiva (chemosis) is minimal. However, in some individuals the chemosis can be much more of a significant issue. This includes following lateral canthal procedures, and procedures in individuals with dry eye after surgery. Typically time and ocular lubrication with artificial tears and ointment are the appropriate treatment.
