Abstract
[Display omitted]
•This is a new clinical phenomenon: a contralateral scotoma arising from monocular pathology.•We suggest this unique case is best understood as plasticity of the retinotopic map in the adult visual cortex.•We hypothesize that top-down inhibition of visual cortex can be generated from higher centers.
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.
