Ptosis in childhood may both impair normal visual development and be cosmetically disfiguring. Ptosis may sometimes be a component part of a more extensive disorder involving the extraocular muscles, facial structures, or nervous system. Each patient must receive a thorough ocular examination, as well as careful assessment of the ptosis itself. Optimum outcome following surgical repair depends on the correct choice of operation for the specific type of ptosis and degree of levator muscle function.
