title: Nitric oxide synthase in developing retinas and after optic tract section.
abstract: We compared the pattern of nitric oxide synthase (NOS) immunoreactivity in retinas of rats during normal development and after unilateral transection of the optic tract at postnatal day 7. NOS was first detected in the second postnatal week in the inner nuclear and inner plexiform layers. There was no detectable difference in the overall pattern of immunoreactivity between normal retinas and retinas with severe loss of ganglion cells due to the lesion. We suggest that NOS may have a role in synaptic and vascular development in the inner retina, but is unlikely to play a major role in normal physiological retinal ganglion cell death or axotomy-induced cell death.
