Homonymous Central Scotomatous Visual Field Defect in a Patient with Lateral Geniculate Nucleus Infarction

초록

Incongruous visual field defects, such as sectoranopia, can result from lateral geniculate nucleus infarction. We present a rare case of right lateral geniculate nucleus infarction that manifests as a left inferior homonymous paracentral scotoma. According to the retinotopic organization of the visual tract, central vision from the macula is delivered to the occipital pole via the posterior portion of the lateral geniculate nucleus. Consequently, not only can occipital pole infarction lead to central visual loss, but partial lateral geniculate nucleus infarction can also produce similar manifestations of central visual loss.
