Can anyone please explain that how P C A damage causes Homonomous Hemianopsia with macular sparing? How does it spare the macula??




  #2

the area of the visual cortex that provide for the sight of the macula has a dual blood supply, from MCA and PCA. Thats why occlusion of the PCA causes macular sparing, becuase the mca still provide blood to that part of the cortex. The rest of the visual cortex only gets blood via the PCA
