title: Retinal slippage fold causing a matching contralateral scotoma.
abstract: We describe a unique case in which a retinal slippage fold after right retinal detachment surgery resulted in a contralateral monocular scotoma. The scotoma in the left visual field matched the right retinal fold in visual space. This previously undescribed phenomenon could be explained by a lack of response from visual cortical neurons receiving inputs from the redundant folded retina. This may represent a top-down plasticity in the cortical retinotopic map.
