Ptosis (Eyelid Drooping)

Ptosis, Eyelid Drooping, Symptoms and Causes

Ptosis (Drooping of the Eyelid) Definition

Ptosis, or drooping of the eyelid, occurs when the upper eyelid falls to a position lower than normal. In severe cases, the drooping eyelid can cover part of or the entire pupil and interfere with vision. In that instance, the resulting condition is called amblyopia.

Ptosis (Drooping of the Eyelid) Symptoms

One of the most obvious eye ptosis symptoms is when one or both eyelids droop. Increased tearing might occur and, in severe cases, vision may be hampered.

Ptosis (Drooping of the Eyelid) Causes

Ptosis is caused by:

  • Weakness of the muscle that is responsible for raising the eyelid
  • Damage to nerves that control the muscles
  • Loose skin on the upper eyelids

In addition, eye ptosis causes include:

  • The aging process
  • A congenital abnormality that existed before birth
  • A result of injury or disease.

Risk factors for eye ptosis include aging, diabetes, stroke. Other conditions, including some cancers, can also have an affect on the nerves or muscles.
