Course
PCA strokes and macular sparing — occipital localization, visual fields, and MRI/CTA (Advanced)
Advanced course: PCA/occipital strokes often cause homonymous visual field loss; some people have ‘macular sparing’. Learn localization concepts, how formal field testing helps, and how CT/MRI/CTA detect ischemic vs hemorrhagic causes
