PURPOSE
The purpose of this study is to evaluate sensory function and stereoacuity in patients showing orthophoria after surgery in exotropes, and to elucidate factors influencing postoperative improved sensory status METHODS: We prospectively studied 45 patients showing orthophoria or exophoria within 4 prism diopters after strabismic surgery in exotropes. Three tests (Worth-4-dot test, Bagolini striated lens test and Titmus test) were performed at pre and postoperative period. We studied the effect of different variables (age at surgery, visual acuity, angle of deviation, Bagolini striated lens test, Titmus test, anisometropia, and fusional status) with suspected clinical influence on the sensory and motor outcomes. RESULTS: In Worth-4-dot test, 34 patients (75.6%) showed improvement after surgery. Thirty-three patients (73.3%) and 35 patients (77.8%) showed improvement respectively in the Bagolini striated lens test and Titmus test. Thirty-eight patients showed improvement in 2 or more tests after surgery and 7 patients showed no change. Of patients showing preoperative abnormal response in each test, 21 patients (65.6%) in Worth-4-dot test, 14 patients (53.8%) in Bagolini striated lens test, and 22 patients (68.8%) in Titmus test showed normal response at postoperative 6 months. Of 3 tests and other factors, Bagolini striated lens test was the only factor predicting postoperative sensory recovery (x2=4.18, P<0.05). CONCLUSIONS: In patients showing orthophoria or exophoria within 4 prism diopters after strabismic surgery in exotropes, Bagolini striated lens test was the only meaningful factor predicting postoperative sensory recovery |
