Abstract
Purpose
To report the clinical effect of an eyelid stretching exercise in 8 cases of overcorrected congenital ptosis after levator resection and present a literature review.
Case summary
Eyelid stretching exercise was performed by pushing the margin of the upper eyelid down. If margin reflex dis-tance 1 (MRD1) asymmetry was larger than 1.5 mm compared with the other eyelid after the stretching exercise for 2 weeks, the exercise was extended for 1 more week. This study included 8 eyes of 8 patients who performed eyelid stretching exercise for 2 weeks when overcorrected 1 week after undergoing levator resection. We compared preoperative MRD1 and postoperative MRD1s for 1 month. Overcorrection was corrected satisfactorily in all patients with bilateral symmetry with eyelid stretching ex-ercise for 2 weeks. Additional exercise did not affect MRD1.
