PURPOSE: The effects of aging on retinal nerve fiber layer (RNFL) thickness should reflect the age-related losses in retinal ganglion cells (RGCs), but published data suggest that the relative rate of thinning of RNFL thickness with age is less than predicted by age-related losses of RGCs. Therefore, the present study ...
