Figure 1 Adult intermittent exotropia, pre and postoperative examination.
Notes: Orthoptic examination at near distance without monocular occlusion, (A). After 30 minutes, monocular occlusion shows a greater degree of exodeviation, (B). Two weeks postoperatively, we observed a satisfactory result from the intended undercorrection surgery protocol, (C). Postoperative examinations, including orthoptic measurements with the prism cover test, were performed at 1 or 2 weeks, 3 months, 6 months and 1 year postoperatively. Alignment at distance fixation was recorded at the most recent postoperative follow-up visit, which was at least 6 months postoperatively. Surgical outcomes of alignment were classified as successful if exodeviation was <10 PD, undercorrection if exodeviation was ≥10 PD, and overcorrection if esotropia was presented with subjective diplopia. Near stereoacuity was measured pre and postoperatively by using amblyoscope. Results were classified as no binocular vision, fusion, or stereopsis.
