Bottom Line: There was a significant difference in the latency and amplitude of mfVEP between the amblyopic and fellow eyes.In contrast, there was no difference in mfVEP latency or amplitude between the fellow eye and normal control eyes.These results suggest that mfVEP may be used as an alternative objective method for diagnosis and monitoring of anisometropic amblyopia.

ABSTRACT

Purpose: To investigate multifocal visual evoked potentials (mfVEP) of the amblyopic and fellow eye in amblyopia due to anisometropia.

Methods: We recorded mfVEP in both eyes of 15 anisometropic amblyopic patients and 15 normal control subjects. The responses from the central 7.0 degrees arc of the visual field were measured, and changes in latency and amplitude were compared between the amblyopic, fellow, and normal control eyes.

Results: There was a significant difference in the latency and amplitude of mfVEP between the amblyopic and fellow eyes. The responses in the central region of the visual field (rings 1 and 2) had a longer latency and smaller amplitude in the amblyopic eye. In contrast, there was no difference in mfVEP latency or amplitude between the fellow eye and normal control eyes.

Conclusion: These results suggest that mfVEP may be used as an alternative objective method for diagnosis and monitoring of anisometropic amblyopia.

f2-opth-4-849: The multifocal visual evoked potentials recorded from the amblyopic right eye of the same subject in Figure 1. The inset shows the pathologic foveal trace with decreased amplitude and increased latency.

Mentions: Figure 1 shows a monocular pattern reversal mfVEP recorded from the fellow eye of an amblyopic patient (Case 9 in Table 1). The inset shows a typical normal single foveal response. Figure 2 shows a monocular pattern reversal mfVEP recorded from the amblyopic eye of the same patient. The amplitude of the center stimulus hexagon (ring 1) is attenuated compared with the trace of the fellow eye and traces adjacent to it.
