Monocular 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...
متن کاملMonocular diplopia‐associated migraine‐like headache induced by nicotine withdrawal
We describe an extremely rare case of migraine-associated monocular diplopia developed in a 23-year-old man after sudden cessation of smoking. The physical examination and brain MRI scan were unremarkable. The symptoms resolved after starting nicotine patch. We reviewed the literature and discussed the diagnosis and possible mechanism of this phenomenon.
متن کاملConsequences of Monocular Diplopia for the Contrast Sensitivity Function
Though the human eye generally creates a single image on the retina, the literature contains many examples showing perceptual monocular diplopia. Previously, monocular diplopia resulting from astigmatic defocus has been demonstrated to cause a notch (local minimum) in the contrast sensitivity function (CSF). We examine Verhoeff's (1900) model which explains how monocular diplopia can occur thro...
متن کاملMonocular diplopia due to spherocylindrical refractive errors (an American Ophthalmological Society thesis).
PURPOSE Ordinary spherocylindrical refractive errors have been recognized as a cause of monocular diplopia for over a century, yet explanation of this phenomenon using geometrical optics has remained problematic. This study tests the hypothesis that the diffraction theory treatment of refractive errors will provide a more satisfactory explanation of monocular diplopia. METHODS Diffraction the...
