METHODS: A total of 23 eyes of 23 patients who had undergone Muller muscle conjunctival resection for residual ptosis between January 2016 and July 2018 were reviewed retrospectively. Margin reflex distance (MRD), interlid crease, and show distance measurements were performed with a ruler in millimeters during the office examination, and the photographs of patients were taken before the procedure and on the 10th day, at the first, third, and sixth months after the procedure.
