A drooping upper eyelid is known as?

1. Amblyopia

2. Ptosis

3. Strabismus

4. Lagophthalmos

The correct answer is: Ptosis

A drooping upper eyelid is known as ptosis. This condition can be caused by a variety of factors, such as muscle weakness, nerve damage, or age-related changes. In ptosis, the eyelid descends below its normal position, which can affect vision and the cosmetic appearance of the eyes. The other terms refer to different eye conditions: amblyopia is a vision development disorder also known as "lazy eye," strabismus refers to misalignment of the eyes, often called "crossed eyes," and lagophthalmos involves the inability to close the eyelids completely, which can lead to eye exposure and dryness. Understanding these distinctions helps in identifying and addressing various ocular conditions properly.
