However, they may exist in patients with lesions in the optic pathways anterior to the lateral geniculate bodies. Wilbrand and Sänger2 pointed out that sometimes metamorphopsia and micropsia precede the formation of absolute scotomas in cases of retinal lesions. They considered these conditions as retinal metamorphopsia and micropsia.
Recently we encountered unusual visual symptoms in a patient with a verified tumor of the chiasmal region. The bitemporal field defects were incomplete. There were spotty asymmetric scotomas with islands of micropsia and of teleopsia limited to the temporal halves of the fields of vision.
