Causes

Ptosis occurs when the muscle that usually raises the eyelid (levator palpebrae superioris) is not strong enough to do so. It can affect one eye or both eyes and is more common in the elderly, as muscles in the eyelids may begin to deteriorate. One can, however, be born with ptosis, as it is hereditary. Ptosis may be caused by damage/trauma to the muscle which raises the eyelid, or damage to the nerve which controls this muscle. Such damage could be a sign or symptom of an underlying disease such as diabetes mellitus, a brain tumor, and diseases which may cause weakness in muscles or nerve damage, such as myasthenia gravis.

Treatment

Treatment depends on the type of ptosis.


Aponeurotic and congenital ptosis may require surgical correction if severe or if cosmesis is a concern. Surgical procedures include:

  • Levator resection
  • Frontalis sling operation

Non-surgical modalities like the use of "crutch" glasses to support the eyelid may also be used.


Ptosis that is caused by a disease will improve if the disease is treated successfully.
