In lesions of the visual pathway, macular vision is often spared due to the large size of the macular area, and because some areas have a …
WebThe first neurons of the visual pathway are the retinal ganglion cells (RGC) which are located in the innermost retinal layers (Fig. 1). First, light needs to cross all inner layers before it reaches the photoreceptors, which are neurons specialized on the reception and conduction of visual stimuli. http://kellogg.umich.edu/theeyeshaveit/anatomy/visual-pathway.html
