Title |
Action Potential Dispersion within the Optic Nerve |
Creator |
Michael R. Swenson, MD; Barrett Katz, MD |
Subject |
Optic Nerve; Pattern Reversal Evoked Potential; Amplitude Loss; Demyelinated Segment |
Description |
Amplitude loss and latency delay of the major positive potential (P-100) of the pattern reversal evoked potential (PRVEP) accompany optic neuritis, and may persist after vision in the affected eye normalizes. Amplitude loss suggests persistent conduction block in the optic nerve. However, we propose that signal dispersion within the optic nerve may alone degrade amplitude, more prominently when the distribution of axon action potential velocities is broadened by traversal of a demyelinated segment. |
