What is Ptosis?
Ptosis is a drooping of the upper lid that can restrict peripheral vision. The brow muscles usually become overactive to compensate for the drooping lid, which results in “tired” eyes. Ptosis is caused by an abnormality or weakness in the eyelid muscles (levator and mullers muscles). This can be congenital (occurring at birth) or acquired due to age or neurogenic, myogenic, or mechanical reasons. Treatment depends on the type of ptosis you have. The most common type is age-related ptosis, which requires that the levator muscles are repaired in order to raise the upper lid.
