Visual evoked response in different types of amblyopia before and after occlusion therapy

Visual evoked response (VER) was analysed in control eyes and in different types of amblyopias. A general trend of a non-linear decrease in latency with an improvement of visual acuity has been noted. Individual correlation co-efficients between visual acuity and VER parameters in different types of amblyopias as compared to whole population showed no significant changes. The correlation co-efficient between post-treatment visual acuity and latency reflects a general trend of a non-linear decrease in latency with an improvement of visual acuity.
