In ophthalmology, ptosis is an abnormally low position (drooping) of the upper eyelid.
Depending upon the cause it can be classified into:
- Neurogenic ptosis which includes IIIrd cranial nerve palsy, Horner's Syndrome, Marcus Gunn jaw winking syndrome, IIIrd cranial nerve misdirection.
- Myogenic ptosis which includes myasthenia gravis, myotonic dystrophy, ocular myopathy, simple congenital ptosis, blepharophimosis syndrome
- Aponeurotic ptosis which may be involutional or post-operative.
- Mechanical ptosis which occurs due to edema or tumors of the upper lid
[edit] Treatment
One of the surgical procedures that can partially correct ptosis is called a frontalis lift, where the eyelids are connected by fascia ties to the frontalis muscles (the muscles in the forehead) This can be done by using synthetic mesh materials, or, for more advanced patients, a length of tissue from the tendon in the upper leg can be used. Surgery usually requires being modified after about ten years.
