Clinical Norms For Visual-Evoked Potential Testing FSUCO Electro-Diagnostic Laboratory.

The purpose of this study was to develop clinical norms, with regard to VEP testing, for the FSUCO Electro-Diagnostics Laboratory. Ten randomly selected subjects were tested with reversing checkerboard patterns of various sizes. Serial testing was performed monocularly and in random order. The results were analyzed for amplitude, latency and variability. The efficacy of VEP testing for investigating the visual pathway for evidence of occult insult is well docmnented. Development of these norms will allow the use of this technique for clinical decision making in selected cases.
