Purpose: 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.
Material and 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.
