متن کاملDynamic Analysis Comparing Esophoria and Exophoria
This study analyzed eye movements of an esophoric and an exophoric subject using an infrared limbus-tracking device. Converging and diverging one and two degree step stimuli were given to both subjects. Preliminary results suggest that dynamic differences may exist between the two populations.
