Optic radiation meyer's loop

WebThe optic radiations arise from the lateral geniculate body in three bundles. The anterior bundle curves anterolaterally above the temporal horn (Meyer’s loop), usually reaching beyond the anterior limit of the temporal horn, and then loops backward along the inferolateral wall of the atrium. WebWhat is Meyer’s loop? The inferior or ventral bundle, known as Meyer’s loop, travels around the temporal horn. This bundle makes a wide anterior and lateral loop around the temporal horn. of the lateral ventricle before curving around the posterior atrium to reach the occipital cortex. What would be the result of a lesion in the optic chiasm?
