Electrophysiological detection of aniseikonia.
Steady-state and transient Visually Evoked Responses (VERs) were used to verify a paradoxical aniseikonic condition in an anisometropic patient. Testing on the Remole multimeridional horopter apparatus indicated that a 2% overall magnification was required for the more hyperopic eye to eliminate ocular image size differences. A special lens correction for the patient's aniseikonia resulted in a very significant improvement in visual comfort and binocular function.
