COMPARISON OF CYCLODEVIATION IN CASES OF INFERIOR OBLIQUE OVER ACTION FOLLOWING CORRECTION BY SCHEIE PARK PROCEDURE VERSUS ELLIOT AND NANKIN PROCEDURE

Introduction: Excessive elevation of the eyeball in adduction is a consequence of inferior oblique muscle over action (IOOA), which is a common disorder of ocular motility and is reported in 70% of patients with esotropia and 30% of patients with exotropia and cyclodeviation is a well-known feature of oblique muscle disorders. Objective: To objectively compare the cyclodeviation before and after surgery by taking fundus photographs and measuring the disc-foveal angle in patients with inferior oblique over action undergoing correction by Scheie Park procedure versus the Elliot and Nankin procedure. Settings and Design: Prospective comparative and interventional randomized trial Methods and Material: A total of 40 patients having inferior oblique over action grade 2 or above and age above 5 years were included in the study. Patients were randomly divided into 2 groups with group A patients undergoing Scheie Park?s procedure and group B patients undergoing Elliot and Nankin procedure. Cyclodeviation was estimated by measuring the disc-foveal angle (DFA) on fundus photograph. Correction in cyclodeviation achieved by the two procedures was then compared. Statistical Analysis was carried out using SPSS 16.0 software. Results: : We reviewed the two groups of 20 patients each and noted that there was no statistically significant difference in correction of cyclodeviation (P > 0.05), between both groups at each postoperative visit. Conclusions: We conclude that both the above mentioned procedures are equally effective in cases of inferior oblique overaction
