İntermitan Ekzotropyada Cerrahi Başarıyı Etkileyen Faktörler

Pur po se: To determine the factors that influence surgical success in patients with intermittent exotropia.\udMa te ri al and Met hod: We retrospectively evaluated the records of patients with intermittent exotropia who were diagnosed, operated,\udand followed up. Successful outcome was defined as alignment ≤10 prism diopters (PD) esophoria or exophoria at the last follow-up visit.\udThe clinical findings, exodeviation types, surgical ages, operation types, preoperative and postoperative deviation amounts, presence of\udanisometropia and amblyopia, presence of A- or V-pattern, and presence of binocular vision and stereoacuity of patients were evaluated.\udWe investigated the independent variables that affected the surgical success in intermittent exotropia patients.\udRe sults: Among the 379 patients included in the study, 266 (70.18%) underwent surgery, and the success rate was 68.05% (181\udpatients). In this successful surgery group, mean deviation was 25.82±11.27 PD at near and 30.80±10.59 PD at distance versus\ud30.93±12.47 PD and 34.92±11.02 PD, respectively, in the unsuccessful surgery group. There was a statistically significant difference\udbetween the two groups. Preoperative factors, such as presence of binocular vision preoperatively, and postoperative factors, such as followup\udperiod and the patients' deviation amount in the 1st week and 6th month, were found to affect the surgical outcome.\udDis cus si on: The success rate of surgical treatment of intermittent exotropia increases in the patients with presence of fusion and low\udpreoperative deviation amounts. Also, in the early postoperative period, orthophoric or ≤10 PD esophoric patients have a higher final\udsurgical success rate. (Turk J Ophthalmol 2013; 43: 107-12
