What are the common causes of drooping eyelids?

Drooping eyelids, also known as ptosis, can occur for several reasons. Aging is a common cause because the muscles that lift the eyelids can weaken over time. Nerve problems can also lead to ptosis. For example, if the nerve that controls the eyelid muscles is damaged, it may cause the eyelid to droop. Muscle disorders, such as myasthenia gravis, can make the eyelid muscles weak and unable to hold the eyelid open.

Other causes include injury or trauma to the eye area, which can damage the muscles or nerves involved in lifting the eyelid. Surgery around the eyes can sometimes affect the eyelid muscles, leading to drooping. In some cases, ptosis is present from birth due to improper development of the eyelid muscles. Understanding the cause of drooping eyelids is important for determining the best treatment approach.
