An attempt was made to clarify whether the site of postchiasmal lesions affects subjective perception of homonymous visual field defects during stimulation with flickering random dot patterns (white noise-field). Out of 56 patients with homonymous hemianopia, 38 (68%) perceived scotomata in this situation, but 18 (32%) discerned none at all. Neuroradiologic superposition of cerebral lesions det...

OBJECTIVE This study sought to validate the use of the Self-Report Assessment of Functional Visual Performance (SRAFVP) as a measure of the severity of activity of daily living (ADL) limitations in people with homonymous hemianopia (HH). METHOD Thirty adults with HH from stroke rated their level of difficulty in completing the SRAFVP. RESULTS The Cronbach's αs of the SRAFVP and its three su...

Copyright © 2007 Massachusetts Medical Society. A 62-year-old man has sudden weakness of the left arm and leg and slurred speech. Except for untreated hypertension, his medical history is unremarkable. He is a current smoker with a smoking history of 45 pack-years. On arrival at the emergency department 1 hour 15 minutes after the onset of symptoms, he reports no headache or vomiting. His blood...

A 58-year-old man presented with a 6-month history of headaches, progressive left homonymous hemianopia, and right-sided paresthesias. MRI revealed bilateral parietal and occipital enhancing lesions (figure 1, A–C) suggestive of cerebritis or posterior reversible encephalopathy syndrome due to history of hypertension. Worsening vision prompted neuroimaging 18 months later, showing contrast-enha...

Methods: Forty-three participants with homonymous hemianopia were fitted with temporary press-on Fresnel peripheral prism segments of 40 prism diopters. Follow-up questionnaires evaluating functional benefits for mobility were administered in the office at week 6. Participants who continued wearing the prisms were interviewed again by telephone after a median of 12 months. Primary outcome measu...

INTRODUCTION Occipital lobe seizures are a recognized manifestation of diabetic nonketotic hyperglycemia, though not as common as focal motor seizures. Occipital lobe white matter T2 hypointensity may suggest this diagnosis. METHODS We present a case of a 66-year-old man with hyperglycemia-related occipital lobe seizures who presented with confusion, intermittent visual hallucinations, and ho...

Homonymous hemianopia (HH) is the most common cortical visual impairment leading to blindness in the contralateral hemifield. It is associated with many inconveniences and daily restrictions such as exploration and visual orientation difficulties. However, patients with HH can preserve the remarkable ability to unconsciously perceive visual stimuli presented in their blindfield, a phenomenon kn...

BACKGROUND Visual loss following stroke impacts significantly on activities of daily living and is an independent risk factor for becoming dependent. Routinely, allied health clinicians provide training for visual field loss, mainly with eye movement based therapy. The effectiveness of the compensatory approach to rehabilitation remains inconclusive largely due to difficulty in validating funct...

A 25-year-old man was admitted on June 17, 1967, with a right hemiplegia of sudden onset. Three episodes of pain, swelling, and red blotchy discoloration of both feet and legs, each lasting 2 to 4 weeks, had occurred over the preceding year. During this period, he noticed transient burning and tingling in his fingers. He was apyrexial and normotensive; pulse rate 90/ min.; atrial fibrillation w...
