Abstract:
PURPOSE: To evaluate clinical features of patients who have experienced decreased exodeviation after refractive error correction. METHODS: Thirty-four patients who experienced decreased exodeviation after refractive error correction between 2003 and 2010 were evaluated. Visual acuity, refractive errors, reported age at onset, duration of wearing glasses, stereopsis, and function of fusion were evaluated. RESULTS: The present study included 34 patients with intermittent exotropia. Before correcting refractive errors, the mean visual acuity was 0.34 +/- 0.27 for the right eye and 0.37 +/- 0.27 for the left eye according to log MAR. After refractive error correction, mean visual acuity improved to 0.12 +/- 0.11 for the right eye and 0.11 +/- 0.11 for the left eye according to log MAR. Before correcting refractive errors, the amount of deviation was 18.1 +/- 7.4 PD at near and 13.5 +/- 8.4 PD at far. However, after correcting refractive errors, the amount of deviation decreased to 5.8 +/- 8.6 PD at near and 4.5 +/- 7.6 PD at far (p < 0.05). CONCLUSIONS: The clinical characteristics of children who have decreased exodeviation after correcting refractive errors is shown by a greater amount of deviation at near than at distance and good fusional vergence and stereoacuity. Because correcting refractive errors by wearing appropriate glasses can decrease exodeviation, the authors of the present study recommend correcting refractive errors as the initial management for exotropia.
