Abstract

We evaluated the degree of ptosis, the function of levator muscle, and postoperative interval to recovery of ptosis in 20 patients who underwent scleral buckling for retinal detachment. The MRD 1(Margin reflex distance 1), function of levator muscle by Berke method and interpalpebral fissure height were evaluated at preoperative day and 1, 3 days, 1, 2, 4, 6, 8, weeks, and 6 months after surgery. The results were compared according to age, gender, extent of buckling, location of buckle. All patients were reported to develop ptosis at postoperative day one, and 20% of them showed mild ptosis persistent until 8 weeks after surgery. The decrement of MRD 1 was statistically significant until postoperative 2 weeks, but impaired function of levator muscle was statistically significant until postoperative 6 weeks(P<0.05). The postoperative interval to recovery of MRD 1 was delayed in group of old age(order than 40 years), in male and when the buckle was located under the superior rectus muscle(P<0.05). The postoperative interval to recovery of function of levator muscle was delayed in group of female, when the buckle extent was more than 180 degrees and when the buckle was located under the superior rectus muscle(P<0.05).
