| Abstract | ||||
| Purpose: To evaluate inferior oblique recession as a primary surgical procedure for treatment of superior oblique palsy. Setting: Mansoura Ophthalmic Center, Mansoura University, Mansoura, Egypt. Methods: Prospective, interventional study comprised 25 patients diagnosed as superior oblique palsy. Complaint was assessed preoperatively & postoperatively e.g., Abnormal head posture, diplopia & cosmetically unaccepted vertical deviation. Vertical deviation in primary position was measured by alternate prism-cover test preoperatively, at 1 week, 3 months and 6 months postoperatively. Inferior oblique overaction was assessed preoperatively & postoperatively. All patients underwent IO recession as a primary surgery for treatment of SOP. Successful outcome was defined as hypertropia of 5 prism diopters (PD) or less in primary position. Results: The study comprised 25 patients who underwent IO recession for treatment of SOP. the median age at the time of surgery was 16 years (range 2 to 50 years) comprising 12 males (48%) and 13 females (52%). AHP was found in 21 patients (84%) preoperatively which was improved in 17 patients postoperatively. Postoperative IOOA (grades +2 or more) was considered residual IOOA which was found in 4 patients. Hypotropia in adduction (IO under action) was found in 1 patient. The median hypertropia in primary position decreased significantly postoperatively (P=≤0.001*). There was overcorrection in one patient. The successful outcome was found in 84% (21 of 25 patients). Conclusion: Single standardized, nongraded recession of ipsilateral IO was effective in reducing vertical deviation in primary position in cases of SOP & improving AHP & diplopia without creation of new symptoms. | ||||
