Objectives: To describe the hallucinations occurring as a result of a macular hole in each eye and to investigate the neural basis. Methods: Psychophysical observations including sketches of the hallucinations calibrated for size. Results: All the hallucinations were of the geometric (patterned) type and lasted for only 9 few days. Conclusions: The observations can be explained on the basis of a deafferentation model, which is described in some detail. It is proposed that the hallucinations result from activation of the blobs of area VI and the stripes of area V2 in the visual cortex. A theory is proposed to account for the disappearance of the hallucinations by a filling in mechanism.
