[Flash electroretinography and pattern-type visual evoked potentials in early glaucoma].
OBJECTIVE
The aim of this prospective study was to evaluate diagnostic sensitivity of flash-erg, oscillatory potentials (OPs), and pattern-visual evoked potentials (pVEP) in early glaucoma.


METHODS
Erg, OPs and pVEP were registered in 416 eyes primary open angle glaucoma (120 eyes), normal tension glaucoma (137), ocular hypertension (74), glaucoma-like discs (86) in age-matched groups, by Tomey 400.


RESULTS
There were no statistically significant differences between parameters of flash-erg and pVEP of examined population and control group. Significant reduction in OPs amplitude in NTG patients were found.


CONCLUSIONS
Flash erg and pVEP have low diagnostic value in early glaucoma. OPs could be useful in scientific research on pathogenesis of glaucomatous neuropathy.
