Changes of corneal tomography in patients with congenital blepharoptosis

Abstract The study aimed to evaluate the effect of drooped eyelid on corneal tomography in congenital blepharoptosis patients. Sixty-four patients with congenital blepharoptosis and 64 age- and sex- matched healthy subjects were included. According to the eyelid margin to corneal light reflex distan...

Sixty-four patients with congenital blepharoptosis and 64 age- and sex- matched healthy subjects were included.
