Extraocular Muscle Insertions in Iranian People

Introduction: To determine the distance of Extraocular Muscle (EOM) insertions to limbus in Iranian people. Materials and Methods: 173 cases (173 eyes) were entered in an observational cross-sectional study. Patients referred to the Khatam-al-Anbia Hospital were included. All of them had to be operated on specific indications. After 360 peritomy in the operating room, the distance between EM insertion and limbus were measured with the same caliper. All measurements were done by the same surgeon. Results: 173 eyes of 173 cases (85 female, 49.13%) with the mean age of 39.70±4.22 years were evaluated. 114 eyes were left eyes (65.89%) and the others were right eyes. The mean and standard deviation of the distances of EM to limbus were obtained as mentioned below: Superior Rectus (SR): 8.63±0.89 millimeter, Inferior Rectus (IR): 6.36±0.40 millimeter, Lateral Rectus (LR): 7.029±0.35 millimeter, Medial Rectus (MR): 5.30±0.37 millimeter. Conclusions: The obtained values will be helpful in vitreoretinal surgery and specifically in strabismus surgery. Please cite this paper as: Moosavi MN, Sharifi M, Shafiee M.
