The Analysis of Ocular Deviations Between Dominant and Non-dominant Eye Using Video-oculography (VOG) in Intermittent Exotropia

Inje University30 enrolled

Overview

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. Investigators analyzed angles of ocular deviations in dominant and non-dominant eyes, compared with values of VOG and deviation angles of the alternative prism cover test.
