BACKGROUND Homonymous hemianopia (HH) is an anisotropic visual impairment characterized by the binocular inability to see one side of the visual field. Patients with HH often misperceive visual space. Here we investigated how HH affects visual motor control. METHODS AND FINDINGS Seven patients with complete HH and no neglect or cognitive decline and seven gender- and age-matched controls view...

Introduction. Observation of open-ring enhancement in magnetic resonance imaging (MRI) is considered a specificity marker for diagnosing pseudotumoral multiple sclerosis (MS). This finding is of great value in the differential diagnosis of tumefactive lesions. Case Report. We describe a 55-year-old white woman, with previous history of ovarian cancer and recent history of fatigue and bilateral ...

A 41-year-old woman showed bilateral monocular polyopia and an incomplete, right-sided homonymous hemianopia following bilateral cerebral strokes confirmed by neuroimaging. She was tested with briefly-presented visual stimuli to determine whether her polyopic images varied with visual field position of stimuli which evoked them. Stimuli close to her scotoma elicited polyopic images at shorter l...

Purpose of the study was to compare Rarebit Perimetry (RP) with Standard Automatic Perimetry (SAP) in patients with ischemic retrochiasmal lesions. Seventeen patients with homonymous hemianopia underwent SAP and RP. Correlation between the two techniques was evaluated, congruent defects were quantified in the spared hemifield and residual vision areas were investigated in the blind hemifield. A...

The characteristics of stroke in baboons produced by transcranial occlusion of the middle cerebral artery were studied by clinical examination and serial cinematographic studies, the animals being maintained for three years following the stroke. The characteristic deficit in all animals was an initial, fairly dense faciobrachial weakness with, in a few instances, some accompanying leg weakness ...

A 73-year-old woman with a history of hypertension and a recent stroke presented with recurrent nonsensical speech and visual problems. One month prior, she had been diagnosed with a stroke, after sudden-onset speech and visual difficulties that resolved after a few hours. Thirteen days before, she had had a second episode of similar symptoms. She was seen in our institution after a few hours o...

PURPOSE To evaluate the progressive lesions affecting the visual system in a patient with subacute sclerosing panencephalitis (SSPE). METHODS The authors observed a 15-year-old boy with SSPE. Since the diagnosis was made before the appearance of ocular manifestations, the authors recorded the progressive ocular lesions using various ophthalmic examinations. RESULTS The patient showed no oph...

A 31-year-old woman with pure red cell aplasia presented with motor aphasia and right homonymous hemianopia due to a left temporal and parietal lobe infarction. Magnetic resonance angiography revealed an occlusion of the left anterior and middle cerebral artery, with the development of moyamoya vessels. She was diagnosed with quasi-moyamoya disease and subsequently underwent direct and indirect...

BACKGROUND Visual loss associated with thoracic surgery has been reported mostly after coronary angiography or bypass surgery. The position of video-assisted thoracic surgery (VATS) is usually lateral, thus not compressive to the globe. Visual loss after VATS has not been reported. Herein we report a patient without any cardiovascular risk factors who experienced transient cortical blindness af...
