acquired ptosis

Acquired ptosis is the drooping of the upper eyelid that develops after birth. It can result from age-related changes, where the muscles that lift the eyelid stretch or become displaced. Other causes include muscular diseases like muscular dystrophy or myasthenia gravis, or damage to the oculomotor nerve due to conditions such as diabetes, hypertension, atherosclerosis, trauma, or compression. A rare cause is Horner syndrome, which also involves a smaller pupil and reduced sweating on the affected side. Treatment for persistent ptosis is typically surgical, and investigations may be needed to identify underlying causes. Ophthalmoplegia, paralysis of the eye muscles, can also lead to ptosis, often accompanied by double vision and an enlarged pupil.12
