[Combined use of pattern electroretinography and pattern visual evoked potentials in neuroophthalmological practice].
OBJECTIVE
To survey the role of pattern electroretinography (PERG) and pattern visual evoked potentials (VEPs) in the process of clinical evaluation of neuro-ophthalmological cases. The study is illustrated with the electrophysiological findings of 231 patients sent to our laboratory in 2005 because of the suspicion of damage in the optic pathway.


METHODS
The RETIport program of the ROLAND equipment (Wiesbaden-Germany) was used to record PERGs and VEPs. The recordings were done according to the recommendations of the International Society for Clinical Electrophysiology of Vision.


RESULTS
The combined application of PERG and VEP provided useful data on the retino-cortical conduction time and hence demyelinisation. The comparison of the N35/P50 and P50/N90 amplitudes of the PERG recordings greatly promoted the diagnostic procedure.


CONCLUSIONS
The combined application of PERG and VEP methods is recommended in the assessment of optic nerve function of neuro-ophthalmological patients.
