What is the term for drooping upper eyelids?

The term for drooping upper eyelids is "ptosis." This condition refers specifically to the sagging or falling of the eyelid, which can occur in one or both eyes. Ptosis can result from various factors, including muscle weakness, nerve damage, or aging. It can interfere with vision if the eyelid droops significantly, covering part of the pupil.

Understanding this term is essential because ptosis often prompts evaluation and management, especially if it affects the patient's daily activities or vision. Other conditions mentioned, such as strabismus (misalignment of the eyes), blepharitis (inflammation of the eyelid margin), and pterygium (growth of tissue on the eye's surface), are unrelated to the specific issue of eyelid drooping. Familiarity with these distinctions aids in effective communication and diagnosis within the field of ophthalmology.
