We evaluated the effect of part-time patching versus observation on distance exodeviation control in post hoc analyses of 3- to <11-year-olds with intermittent exotropia who were assigned to either patching 3 hours/day or observation in a previously reported randomized clinical trial. The present analysis was limited to a subgroup of 306 participants who at distance fixation spontaneously manifested either a constant or intermittent exotropia or had prolonged recovery after monocular occlusion (a distance control score of 2 or worse using the 0-5 Office Control Score scale) at baseline. We assessed change in control at distance and near fixation, from baseline to 3 months and baseline to 6 months (1 month after discontinuing patching). We found greater improvement in the distance control score with patching than with observation at 3 months (mean difference, 0.4 points; 95% CI, 0.1-0.7) and 6 months (mean difference, 0.3 points; 95% CI, 0.02-0.6). These analyses suggest that part-time patching may improve distance control in children with intermittent exotropia and a control score ≥ 2; however, because this conclusion is based on post hoc subgroup analyses, further studies are needed.[Formula
