  • Title: The visual evoked potentials to the light emitting diode compared to the flash and pattern reversal stimulus.
    Author: Hughes JR, Fino JJ, Hart L.
    Journal: Int J Neurosci; 1989 Aug; 47(3-4):359-66. PubMed ID: 2807772.
    Abstract:
    Light-emitting diode (LED), flash (FL) and pattern reversal (PR) stimuli were used to elicit visual evoked potentials (VEPs) in 16 normal subjects (32 eyes) and 39 patients (78 eyes) with signs of visual system abnormality. Latencies and amplitudes (plus standard deviations) of 5 components of each response, correlation coefficients of the normal and abnormal responses and false negatives and positives are presented for the 3 kinds of stimuli. The data show that responses to LED stimuli are very similar to those of FL stimuli and should be useful in the operating room to monitor the visual pathways, if various endogenous factors known to affect late responses can be stabilized.
