This study proposes new, original methods for diagnosis of glaucoma optic neuropathy--oscillatory potentials (OP) in an electroretinogram (ERG) to a long-term stimulus and in the 30 Hz flicker ERG (with identification of OP at frequencies of 80 to 120 Hz). Twenty-three patients (46 years) aged 40 to 65 years with primary open-angle glaucoma were examined. OP in the 30 Hz flicker ERG (01 and 02) and that in the ERG ON-response to a long-term stimulus have a similar origin and are linked with the light ON-channels of the retinal cone system. O1, O2, and 03 in the 30 Hz flicker ERG reflect the function of neurons in the retinal cone system. The O3 oscillation displays impaired neuronal communications in the retinal ganglion cells.
