Ptosis

  • Ptosis is an abnormally low position (drooping) of {the} upper eyelid
  • Ptosis occurs when {the} muscles that raise {the} eyelid (levator and Müller's muscles) are not strong enough to do so well.
  • It can affect one eye or both eyes and is seen more frequently in {the} elderly, as muscles in {the} eyelids might begin to deteriorate.
  • Compare with dermatochalsis (extra skin and fat)

 

 

Defintion

  • Ptosis is an abnormally low position (drooping) of {the} upper eyelid
  • The drooping might be worse after being awake longer, when {the} individual's muscles are tired.
  • This condition is may be 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.
  • This is why it is especially important for this disorder to be treated in children at a young age, before it can interfere with vision development.

NOTE

There are two 'main' surgeries that might be performed on {the} upper eyelid.
This section addresses Ptosis  which is {the} medical term for drooping of {the}
upper eyelid; it might affect one or both eyes.

The other surgery of {the} upper eyelid addresses excess skin  is repaired by blepharoplasty.

Ptosis occurs when {the} muscles that raise {the} eyelid (levator and Müller's muscles) are not strong enough to do so well. It can affect one eye or both eyes and is seen more frequently in {the} elderly, as muscles in {the} eyelids might begin to deteriorate.

  • Ptosis can be caused by {the} apneurosis of {the} levator muscle, nerve abnormalities, trauma, inflammation or lesions of {the} lid or orbit. 
  • Dysfunctions of {the} levators might occur as a result of a lack of nerve communication being sent to {the} receptors due to antibodies needlessly attacking and eliminating {the} neurotransmitter.
  • Ptosis might be due to a myogenic, neurogenic, aponeurotic, mechanical or traumatic cause and it usually occurs isolated, but might be associated with various other conditions, like immunological, degenerative, or hereditary disorders, tumors, or infections
  • 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.
  • Congenital neurogenic ptosis is believed to be caused by {the} Horner syndrome.
  • In this case, a mild ptosis might be associated with psilateral ptosis, iris and areola hypopigmentation and anhidrosis due to {the} paresis of {the} Mueller muscle. Acquired Horner syndrome might result after trauma, neoplastic insult, or even vascular disease.
  • Ptosis due to trauma can ensue after an eyelid laceration with transection of {the} upper eyelid elevators or disruption of {the} neural input.
  • Other causes of ptosis include eyelid neoplasms, neurofibromas or {the} cicatrization after inflammation or surgery. Mild ptosis might occur with aging.
