What is the term for drooping upper eyelids?

The term for drooping upper eyelids is "ptosis." This condition occurs when the muscles responsible for lifting the eyelid become weak or impaired, resulting in a noticeable sagging. Ptosis can affect one or both eyelids and may vary in severity. It has various causes, including aging, nerve damage, muscle diseases, or congenital issues.

Blepharitis refers to inflammation of the eyelids, often associated with redness, irritation, and crusting. Conjunctivitis, commonly known as pink eye, is an inflammation of the conjunctiva, the tissue lining the eyelids and covering the eye. Asthenopia refers to visual fatigue or discomfort, often experienced after prolonged periods of concentration on visual tasks like reading or using a computer. Understanding these terms helps clarify why ptosis specifically addresses the drooping of the eyelids.
