Summary We estimated cell numbers in the ganglion cell and inner nuclear layers of adult frog (Hyla moorei) retinae, examining normal animals and those with regenerated optic nerves. Analysis of sections stained with cresyl violet showed that cell numbers in a nasotemporal strip, which included the area centralis and visual streak, were comparable between sides for both these cellular layers in normal animals. In line with our previous observations, after optic nerve regeneration cell numbers in the ganglion cell layer had fallen by 35–43% compared to the unoperated sides. By contrast cell numbers remained similar for the inner nuclear layers on the two sides. We conclude that retrograde transneuronal degeneration had not taken place in the inner nuclear layer in response to ganglion cell death.
