DEAR DOCTOR K: My right eyelid droops and interferes with my vision. What can I do about this?
DEAR READER: The medical term for a drooping eyelid is "ptosis" (pronounced TOE-sis). In severe cases like yours, the drooping eyelid can cover all or part of the pupil and interfere with vision. Every part of our body is constantly tugged on by gravity. And something that is constantly being pulled downward (at least when we are standing or sitting) tends to sag. The eyelid is no exception. The effects of gravity can be exaggerated by any injury that weakens the strength of the eyelid.
