Abstract:
This study evaluates visual evoked potential tests using a novel URV device (EPlacement) for electrode placement accuracy based on the 10/20 international pattern versus the standard method. The standard method often uses approximate positions, typically a fixed value (5cm). The research compares wave morphology differences, focusing on latency and amplitude. Clinical reports will be analyzed to correlate pathologies with wave morphology differences, assessing the clinical impact of precise electrode marking. This analysis aims to improve diagnosis accuracy and reliability in electrophysiological tests by identifying waveform discrepancies and their clinical implications.
