Right lateral geniculate nucleus infarct presenting as a left monocular temporal hemianopia

Abstract

Abstract A lesion to the right lateral geniculate nucleus should cause a complete left monocular hemianopia. We present a case of a patient with left eye monocular temporal hemianopia with two MRIs demonstrating an ischemic defect at the right lateral geniculate body as the likely culprit. Patient improved after 4 days.
