| Research Abstract |
The purpose of this study was to determine the contributions of cones and post- photoreceptoral neurons to the a-wave of the photopic ERGs in rhodopsin Pro347Leu transgenic (Tg) rabbits. Post-photoreceptral neural function was completely suppressed by intravitreal injections of CNQX and APB. We found that the percentage contribution of the cone photoreceptorsto the photopic ERG a-waves ranged from 54% to 75% in wild-type (WT) rabbits. In contrast, the percentage contribution of the cone photoreceptors in Tg rabbits ranged from 32% to 51%. These results suggest that the relative contribution of cone photoreceptors to the photopic ERG a-wave is smaller in retinas with inherited photoreceptor degeneration.
