Abstract

Purpose : To measure and analyze angles of ocular deviations between dominant and non-dominant eye using VOG with alternate cover

Methods : Fifteen subjects with intermittent exotropia were included. The subjects were asked to fixate on a black-on-white optotype at 1 m, which subtended a visual angle of 50 min of arc, equating to a Snellen optotype of 20/200. The video files and data about ocular deviations were obtained using VOG with alternate cover test. We analyzed angles of ocular deviations in dominant and non-dominant eyes. Additionally, we compared with values of VOG and deviation angles of the alternative prism cover test.

Results : Among the 15 subjects in this study, the mean age was 7.73(rang, 4-10 years). Seven of 15 subjects have right eye dominance. Ten of the 15 subjects were men. There was no significant difference of ocular deviations between dominant and non-dominant eye in VOG. (P=0.40)

Conclusions : VOG has the advantage of measuring the angle of ocular deviation in both eyes at the same time. We have measured deviation angles mainly in non-dominant eye for surgery using alternative prism cover test. In this study, there is no significant difference of ocular deviations between dominant and non-dominant eye with VOG. Therefore, It seems not to be problem for strabismus surgery even if alternate prism cover test is performed in any eye.
