Abstract

To evaluate the surgical results of superior rectus recession with different amount according to the degree of eyeball deviation.We reviewed the surgical records of 36 eyes in 23 patients who had undergone superior rectus recession and followed up for at least 6 months.Patients were divided into 3 groups according to the degree of deviation : Group 1[8-10PD, 4.0 mm recession], Group 2[11-20PD, 6.0 mmrecession], Group 3[21PD or greater, 8.0 mmrecession].Five PD or less after operation was regarded as acceptable. The success rate of Group 1 was 86.6%at the 6th month, 87.5% at the 12th month, and 83.8%at the 24th onth, respectively.In group 2 those were 87.5%, 75%, and 80%, respectively.In group 3 those were 60%, 50%, and 50%, respectively.The overall success rate as 83.3%at the 6th month, 75% at the 12th month, 75%at the 24th month.These results indicate that superior rectus recession with the different amount according to the degree of eyeball deviation is effective for the deviation under 20PD but not over 21PD.
