2. What causes Ptosis?
Ptosis can result from various factors, each influencing the eyelid’s muscles, nerves, or skin. Congenital ptosis is often due to the improper development of the levator muscle, the muscle responsible for lifting the eyelid. Acquired ptosis, on the other hand, can be attributed to several causes:
– Aging: The most common cause, where the levator muscle’s tendon stretches or separates over time.
– Muscle diseases: Conditions like myasthenia gravis can interfere with the muscles’ ability to function properly.
– Nerve issues: Damage to the nerves controlling the levator muscle, possibly from an injury or medical condition such as diabetes.
– Eye surgery: Complications from eye surgeries can affect the eyelid muscles.
– Trauma: Injury to the eye area can damage the muscles or nerves.
– Tumors or swelling: These can put pressure on the eyelid or the muscles that control its movement.
