متن کاملMonocular Diplopia Associated with a Midbrain Stroke
Background and Purpose Monocular diplopia is often due to intraocular disease. It is rarely the result of cerebral causes, which include lesions in or near Brodmann’s area nineteen, the frontal eye fields or the cerebellum. Monocular diplopia has not been reported in a patient with a midbrain lesion.
متن کاملMonocular Diplopia Caused by Ocular Aberrations and Hyperopic Defocus
As a single aperture, approximately monofocal optical system, the human eye generally creates a single image on the retina. However, the literature contains many reports of perceptual monocular diplopia. While it is easy to understand how distortion may produce monocular diplopia, its reported high incidence in normal eyes is less easily understood. We examine a model which ascribes monocular d...
