Acquired Ptosis Overview

Ptosis (from Greek Ptosis or πτ?σις, to "fall") is a (drooping) of {the} upper or lower eyelid.

The drooping might be worse after being awake longer, when {the} individual's muscles are tired.

This condition is often called "lazy eye", but that term normally refers to amblyopia.


If severe enough and left untreated, {the} drooping eyelid can cause other conditions, such as amblyopia or astigmatism.

Overview

Acquired ptosis is most commonly caused by aponeurotic ptosis. This can occur as a result of senescence, dehiscence or disinsertion of {the} levator aponeurosis. Moreover, chronic inflammation or intraocular surgery can lead to {the} same effect. Also, wearing contact lenses for long periods of time is thought to have a certain impact on {the} development of this condition.

Aponeurotic  ptosis might require surgical correction if severe enough to interfere with vision or if cosmesis is a concern. Treatment depends on {the} type of ptosis and is usually performed by an ophthamolic plastic and reconstructive surgeon, specializing in diseases and problems of {the} eyelid.

Ptosis that is caused by a disease (such as Myasthenia Gravis) will improve if {the} disease is treated successfully.

Treatment

Surgical procedures include: Correction of acquired ptosis might be performed in a number of different ways.

Levator resection (Anterior/External approach)

  • Skin incision
  • Adjustment is based on eyelid position during surgery patient is awake
  • May be combined with cosmetic upper blepharoplasty

Müller muscle resection  (Poster / Internal approach)

  • Ideal for patients with minimal excess skin
  • No visible skin incision
  • May be combined with cosmetic upper blepharoplasty

Frontalis sling operation

  • Required when {the} degree of ptosis is severe
  • Creates a ‘sling’ from {the} frontalis muscle (brow) to {the} eyelid.
  • Often performed for congenital ptosis
  • Allows patient to be asleep since surgical repair is based on formula

Non-surgical modalities like {the} use of "crutch" glasses or special Scleral contact lenses to support {the} eyelid might also be used.
