The objectives of this study were to compare ocular deviation between the seated and decubitus positions in the operating room and assess the outcomes at one day, one month and three months postoperatively. This prospective study included 30 cases; two were excluded because of early reoperation. Mean age was 55 years, standard deviation (SD) 20.3 years. There were 77% females, 70% esotropia, 23% exotropia, 7% hypertropia and 7% hypotropia. The preoperative mean angle of deviations was 21.9±12.6 pupillary distance (PD) at distance and 20.6±4.7 PD at near. Differences in angle at follow-up were non-significant; in the decubitus position, angles were 8±8.2 PD at distance and 7.2±5.8 PD at near, and for seated position, 8.1±8.3 PD and 8.5±7.4 PD respectively. There was no significance difference in measurements for adjusted or non-adjusted patients. The authors report a favourable outcome in 70% immediately after adjustment increasing to 83% at follow-up time points.
