Abstract

Two groups of patients affected by Parkinson's disease (PD) were studied by electroretinography during dark adaptation (AERG) and visual evoked potentials (VEPs): nine patients had never been treated before and 31 were on therapy with L-Dopa plus Carbidopa. A significant reduction in amplitude of the 'b1' wave and 'a' wave and a significant delay of P1 wave with reduction of N1-P1 amplitude in VEPs were observed in both groups. A relationship between AERG and VEP alterations was found only in the group of patients treated with L-Dopa plus Carbidopa (p
