Abstract
We examined possible involvement of nitric oxide synthase (NOS) on ganglion cell death in explant cultures of neonatal rat retina. Survival of retinal ganglion cells was significantly prolonged by a broad-spectrum NOS inhibitor Nω-nitro-<sc>L</sc>-arginine methylester. NADPH diaphorase staining revealed a diffused distribution of NOS activity in neuropils of the inner plexiform layer as well as several neurons in the inner nuclear layer. Moreover, 7-nitroindazole but not aminoguanidine promoted the survival of retinal ganglion cells. These results suggest a crucial role of neuronal NOS-derived nitric oxide in retinal ganglion cell death.<br>
