Panum’s area


A region in the retina of one eye that corresponds to a specific point in the other eye. Stimulation of any point within Panum’s area simultaneously with the corresponding point in the fellow eye results in a single fused percept, allowing for a small degree of retinal disparity while maintaining single binocular vision. The size of Panum’s area varies, being smallest at the fovea and increasing peripherally. It plays a crucial role in sensory fusion and stereopsis.
