Abstract

PURPOSE
To evaluate changes in exodeviation in the seated and supine position during adjustable suture strabismus surgery. METHODS: We measured the deviation angle at distances of 6 m, 2 m, and 33 cm in the seated position and at 2 m, and 33 cm in the supine position by the alternate prism cover test in fifty patients with exotropia. RESULTS: The mean deviation angle was 25.41+/-7.08 PD at 6 m, 25.51+/-7.08 PD at 2 m and 28.09+/-7.54 PD at 33 cm in the seated position. The mean deviation angle in the supine position was 24.68+/-7.40 PD at 2 m, and 27.29+/-8.09 PD at 33 cm. There was no significant difference in exodeviation at the same measuring distance between the seated and supine positions. A significant difference between the exodeviation at 6 m in the seated position and the exodeviation at 2 m in the supine position did not exist. CONCLUSIONS: The distant deviation angle at 6 m in the seated position can be replaced by the deviation angle measured by fixating a target at the ceiling in the supine position during adjustable suture strabismus surgery for exotropia.
