Abstract

Purpose: To study the sensory and motor outcomes of three muscle surgery for large horizontal squint.Methodology: A retrospective study was conducted in patients with large horizontal squint undergoing surgery by a single strabismologist over a period of 1 year. Patients with nystagmus, , incomitant strabismus or previous surgery were excluded. Successful outcome was defined as ocular alignment within 10PD orthophoria for near and distance, residual deviation less than 15PD at 6 months post-operatively.Results: A total of 16 patients were included in the study. The mean age at surgery was 16.31 years. Amblyopia was seen in 3 . 12 patients had exotropia and 4 had esotropia . The mean deviation was 65 +- 5 PD. At 6 months, 50% patients achieved ortho (7 XT and 1 ET patient), residual deviation was in 75% ET and 33.33% XT patients. Consecutive deviation was in 1 XT patient.The study reported that three muscle surgery proves to be a promising option for large angle deviation squint.
