Learn the Optic Nerve Pathway and the Visual Field Defects that occur due to lesions in different parts of the Optic Nerve Pathway, including Homonymous Hemianopia, Bitemporal Hemianopia, Quadrantanopia, Macular Sparing and Macular Degeneration. What is the difference between the Temporal vs Nasal Retina? What defects are there in the visual fields if we have: optic nerve lesions, optic chiasm lesions, optic tract lesions or optic radiation lesions? What is macular sparing? What happens in the lateral geniculate nucleus? What is anopia?
