PURPOSE: To evaluate the clinical effects of conjunctiva-Muller muscle resection through conjunctival incision in anophthalmic patients with mild ptosis. METHODS: Conjunctiva-Muller muscle resection was performed by one surgeon in 8 patients (8 eyes) who had received evisceration or enucleation and responded to 10% phenylephrine solution to correct ptosis. The average age of the patients was 35.87+/-13.4 years. Ptosis was seen from 1 to 34 months after evisceration or enucleation. The preoperative MRD 1 was -2 to 0.5 mm (average: -0.25+/-1.10 mm) and the difference of MRD 1 between before and after 10% phenylephrine use was 2.56+/-0.98 mm. The Muller muscle was resected 7.5 to 9 mm through conjunctival incision during surgery to match the MRD 1 of sound eye. Mean follow-up period after the operation was 2 to 16 months (average: 8.1 months). RESULTS: Postoperatively, the MRD 1 increased by 1.81+/-0.88 mm on the average, corresponding to the improvement in lid elevation after the use of 10% phenylephrine performed before resection. Surgery was successful in most patients, and postoperative difference in MRD 1 was less than 1 mm from the sound eye. No special postoperative complication was observed. CONCLUSIONS: Conjunctiva-Muller muscle resection is one of the effective methods of correcting mild ptosis in anophthalmic patients.
