VISUAL SYSTEM Key points Relations of neural retina to other structures in the eye Knowledge of types of photoreceptor and their distribution across the retina Foveal versus peripheral retina Knowledge of the different cell types that make up the retina There are different types of retinal ganglion cell – thus parallel outputs from the retina and beyond…. Central visual pathways – projections to LGB and other subcortical visual structures Organization of visual fields – partial decussation at optic chiasm, binocularity, topography Projection to primary visual cortex – optic radiations Effects of lesions on visual function Reading Nolte (4th Ed), pgs 397-431 Crossman and Neary, pgs 129-133
