RESUMO
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 distance 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 exercise for 2 weeks. Additional exercise did not affect MRD1. CONCLUSIONS: In congenital ptosis overcorrected after levator resection, medical treatment including eyelid stretching exercise could be considered before undergoing a secondary operation. Eyelid stretching exercise can be effective when performed early before fibrous tissue bonds are too firm.
