Abstract

PURPOSE
Achieving good eyelid position and symmetric palpebral fissure for asymmetric bialteral congenital ptosis would require skillful technique and a lot of experiences of surgeon. Patients were divided into two groups, A and B, in terms of preoperative MRD and the possible relationship between preoperative MRD difference. The outcome of the surgery was studied. METHODS: External levator resection with apponeurotic approach was performed for 19 patients with asymmetric bilateral congenital ptosis from October 1994 to June 2000. According to differences of MRD between the both eyes, patients were divided into two groups. Group A included 8 patients with 1.0~2.0 mm of MRD differences, and group B included 11 patients with more than 2.0 mm of MRD differences. RESULTS: Age of patients ranged from 3 to 20 years (mean 6.1 years) and follow-up period was 9 to 60 months (mean 20 months). Six patients of group A and seven patients of group B showed almost excellent symmetric palpebral fissure. Only one patient of group B had postoperative MRD difference more than 2.0 mm, and none in group A. CONCLUSIONS: Success rate was 100% in group A and 91% in group B, but no statistical difference was found between group A and group B (p>0.05).
