Age related Aponeurotic Ptosis
Eyes | Ophthalmology | Age related Aponeurotic Ptosis (Disease)
Ptosis is a condition characterized by the drooping or falling of the upper or lower eyelid.
Clinically, aponeurotic ptosis is characterized by a mild to severe ptosis with an elevated eyelid crease, deep superior sulcus, thinning of the skin superior to the tarsus, and normal levator function. It means the upper lid moves normally in upward gaze. On downward gaze, the lid will continue to droop.
Causes and Risk factors
Aponeurotic ptosis is the most common type of ptosis. It is cause by attenuation, dehiscence, or disinsertion of the levator aponeurosis from its normal insertion on the anterior inferior one-third of the tarsus.
The common causes of acquired aponeurotic ptosis are: aging, chronic inflammation, use of rigid contact lenses, blunt trauma, and prior ophthalmic surgery. Aponeurotic ptosis can also occur after ocular surgery and eyelid edema.
Diagnosis and Treatment
Most patients with aponeurotic ptosis are asymptomatic with a mild degree of ptosis and do not require surgery. If the degree of ptosis is severe enough to disturb vision or is a cosmetic embarrassment, it can be corrected. Surgical resection of levator gives good results. Surgical procedures also include Müller muscle resection and Frontalis sling operation.
Non-surgical modalities like the use of crutch glasses or special Scleral contact lenses to support the eyelid may also be used. ...
