Transient homonymous hemianopia and positive visual phenomena in patients with nonketotic hyperglycemia.
is a male-female predilection of 2:1. It has been described as freely mobile, well circumscribed, and subcuticular. Although the clinical characteristics of fibrous hamartoma have been variably reported, it has unique microscopic features. All prior cases consistently report well-defined traversing bundles of dense fibrocollagenous tissue, immature loose-textured mesenchyme, and increased areas...
متن کاملOccipital seizures and persistent homonymous hemianopia with T2 hypointensity on MRI in nonketotic hyperglycemia

Occipital seizures in NKH are seldom reported, especially with visual hallucinations and persistent homonymous hemianopia (HH) with characteristic radiological and electroencephalographic (EEG) findings.

Brain damage disrupts these complicated processes, resulting in severe visual impairments including hemianopia. Patients with hemianopia co...
متن کاملhomonymous hemianopia Scanning the visual world : a study of patients
Objectives—This study examined the scanpaths of patients with homonymous hemianopia while viewing naturalistic pictures in their original and also spatially filtered forms. Features of their scanpaths with respect to various saccade and fixation parameters were examined to determine whether they develop compensatory eye movement strategies. The eVects of various lesion parameters including loca...
متن کاملBilateral homonymous hemianopia.
Bilateral homonymous hemianopia occurred in 15 patients seen during a four-year period. Persons with this visual deficit had similarly shaped visual field defects on corresponding sides of the vertical midline for each eye, equal visual acuity which is generally normal, and normal pupil and fundus examinations. The most common causes of the bilateral posterior cerebral artery insufficency were ...
