Suspension recession of inferior oblique versus graded recession technique in V-pattern strabismus with primary inferior oblique overaction (original) (raw)

Delta Journal of Ophthalmology, 2017

Abstract

Purpose The aim of this study was to evaluate the efficacy of inferior oblique suspension recession ‘modified hang-back’ in cases with V-pattern strabismus and primary inferior oblique overaction (IOOA), compared with standard graded recession technique. Patients and methods Thirty patients (60 eyes) presenting with V-pattern strabismus with primary IOOA were enrolled and randomized for inferior oblique weakening intervention − that is, suspension recession (group A), or standard graded recession (group B). Results In group A, the mean postoperative V-pattern exotropia was 4.8±2.7 PD as compared with a mean of 26.42±6.26 PD preoperatively (P≤0.001). Meanwhile, for the esotropic subgroup, the values were 2.57±1.13 and 15.62±4.17 PD, respectively (P≤0.001). For group B patients, the mean V-pattern exotropia was 2±1.5 PD, compared with a preoperative mean value of 23.12±10.66 PD (P≤0.001), and the mean pattern esotropia was 2.28±1.79 PD, compared with a preoperative mean value of 17.14...
