Ptosis is when the upper eyelid droops over the eye. The eyelid may droop just a little, or so much that it covers the pupil (the black dot at the center of your eye that lets light in). Ptosis can limit or even completely block normal vision.
Children and adults can have ptosis. Fortunately, this condition can be treated to improve vision as well as appearance.
Ptosis is corrected by tightening the levator muscle. The function of the levator muscle is to raise the eyelid. Ptosis repair is performed through an incision in the normal crease in the upper lid. … Mild ptosis in childhood can worsen as the person ages, requiring surgical repair in young adulthood.
