Cortical Indices of Impaired Ocular Accommodation and Associated Convergence Mechanisms

The accommodative and fusional vergence mechanisms were examined electrophysiologically in a juvenile suffering from a severe reduction in focusing ability. We used the visually evoked response (VER) to diagnose the accommodation‐vergence insufficiency. The procedure is shown to be effective for monitoring longitudinally the ability of simple orthoptic techniques to restore normal accommodative function.
