PURPOSE: To describe the utility of microperimetry testing in the diagnosis of a bilateral occipital stroke. METHODS: Retrospective case report. RESULTS: A 57-year-old male with hypertension presented with complaints of bilateral blurred central vision and bilateral hypertensive retinopathy with cotton-wool spots. Automated perimetry demonstrated a central scotoma in both eyes that did not respect the vertical midline; however, microperimetry testing revealed a bilateral homonymous hemianopia that suggested cerebrovascular disease which was subsequently confirmed with magnetic resonance imaging...

Sturge-Weber syndrome (SWS) is a rare neurocutaneous syndrome characterised by facial naevus and leptomeningeal angiomatosis resulting in neurological and ophthalmological complications. In its rare variant, SWS type 3, the clinical hallmark of facial naevus is absent which poses a diagnostic challenge. Here, we present an interesting case of SWS type 3 where a child presented twice with prolonged severe unilateral headache mimicking migraine status followed on both occasions with focal seizures. He developed a dense right-sided homonymous hemianopia, and an urgent brain MRI scan was performed which pointed towards the diagnosis of SWS type 3...

Object agnosia is a rare symptom, occurring mainly after bilateral damage of the ventral visual cortex. Most patients suffering from unilateral ventral lesions are clinically non-agnosic. Here, we studied the effect of unilateral occipito-temporal lesions on object categorization and its underlying neural correlates in visual areas. Thirteen non-agnosic stroke patients and twelve control subjects performed an event-related rapid object categorization task in the fMRI scanner where images were presented either to the left or to the right of a fixed point...

INTRODUCTION: People with homonymous visual field defects (HVFD) often report difficulty detecting obstacles in the periphery on their blind side in time when moving around. Recently, a randomized controlled trial showed that the InSight-Hemianopia Compensatory Scanning Training (IH-CST) specifically improved detection of peripheral stimuli and avoiding obstacles when moving around, especially in dual task situations. METHOD: The within-group training effects of the previously reported IH-CST are examined in an extended patient group...

A 52-year-old woman was admitted to our hospital for acute right hemi-paresis, left homonymous hemianopia, and fever. Magnetic resonance imaging of the brain showed multiple cerebral infarctions and transesophageal echocardiography (TEE) revealed a vegetation on the posterior leaflet of her mitral valve. Mitral valve repair was performed under a diagnosis of infective endocarditis (IE). Further multiple cerebral infarctions occurred on the 11th postoperative day, resulting in left hemiplegia and dysarthria...

OBJECTIVE: To describe a rare sign of unilateral brain injury as a form of unwanted blink-associated contralateral eccentric saccades. METHODS: A 62-year-old patient who underwent an ischemic stroke affecting the entire right middle cerebral artery territory came to our attention 1 year after stroke, manifesting with transient contralateral conjugate gaze deviations associated with spontaneous blinking. We complemented the regular neurologic evaluation with brain MRI, study of evoked potentials, electroneurography of the facial nerve, and infrared video-oculoscopy...

Visual symptoms are frequently observed in posterior cortical atrophy compared to typical amnestic Alzheimer's disease (AD). We report the case of a patient with amnestic AD with long-lasting homonymous hemianopia. A 62-year-old woman, who was diagnosed in amnestic AD, complained of visual disturbance. She had left homonymous hemianopia in the perimetry test and left tactile extinction. Regardless of posture, retinotopically leftward error was observed on 21 cm line bisection test. Brain single photon emission computerized tomography (SPECT) showed bilateral temporoparietal hypoperfusion, which was more severe to the right than left side...

Homonymous hemianopia from stroke causes visual disability. Although some patients experience spontaneous improvement, others have limited to no change and may be left with a severe disability. Current rehabilitation strategies are compensatory and cannot restore function. Animal studies suggest that central nervous system plasticity could allow for redirection of lost visual function into undamaged areas of cortex. A commercial therapy system was developed, from which claims of visual field expansion were disputed by independent researchers...

A 27-year-old woman presented with anorexia, weight loss and psychiatric symptoms for the past 4 years. She did not have history of headache, visual disturbances or symptoms of raised intracranial pressure. She was sarcopenic with body mass index of 10.16 kg/m(2)Her systemic examination was normal except for temporal hemianopia suggesting a sellar/suprasellar lesion. Hormonal evaluation revealed pan-hypopituitarism with central diabetes insipidus. Subsequent neuroimaging revealed sellar-suprasellar mass lesion with intense contrast enhancement and leptomeningeal metastases...

We report a case of a 55-year-old man who developed acute-onset narrowing of his visual field. He showed right homonymous hemianopsia without any other neurological symptoms and signs. Brain CT and MRI showed localized hemorrhage (about 1.6 ml) in the left lateral geniculate body (LGB). A cerebral angiography showed no vascular anomalies of cerebral vessels, and the left anterior choroidal artery and left lateral posterior choroidal artery could be visualized well. He had hypertension, polycythemia and dyslipidemia and was a habitual smoker and an alcoholic...

Previous research found that a patient with cortical blindness (homonymous hemianopia) was able to successfully avoid an obstacle placed in his blind field, despite reporting no conscious awareness of it [Striemer, C. L., Chapman, C. S., & Goodale, M. A., 2009, PNAS, 106(37), 15996-16001]. This finding led to the suggestion that dorsal stream areas, that are assumed to mediate obstacle avoidance behaviour, may obtain their visual input primarily from subcortical pathways. Hence, it was suggested that normal obstacle avoidance behaviour can proceed without input from the primary visual cortex...

Studies suggest that a word-length effect of up to 160 ms/letter distinguishes hemianopic dyslexia from pure alexia. However, partial preservation of central vision is common in right hemianopia, but its effects on single-word reading are unknown. Eighteen healthy subjects read single words with a gaze-contingent right hemianopia simulation that varied the degree of central sparing. Mean reading onset time declined with small degrees of central sparing, but the word-length effect did not decrease until sparing exceeded 3...

We present a very rare case of suprasellar germinoma that spontaneously regressed before endoscopic biopsy. An 8-year-old boy was admitted to our hospital due to headache, polydipsia, and polyuria. Neurological examination performed on admission revealed bitemporal hemianopia. Enhanced MRI demonstrated a homogeneously enhanced tumor mass in the suprasellar region obstructing the foramen of Monro. Tests for all serum tumor markers were negative. Plain X-ray and CT scan were performed once and twice, respectively, for seven days between admission and endoscopic biopsy...

Stroke-like migraine attacks after radiation therapy (SMART) syndrome is a rare delayed complication of cerebral radiation therapy. A 53-year-old female initially presented with headache, confusion and left homonymous hemianopia. Her medical history was notable for cerebellar hemangioblastoma, which was treated with radiation in 1987. Her initial brain MRI (magnetic resonance imaging) revealed cortical enhancement in the right temporo-parieto-occipital region. She improved spontaneously in 2 weeks and follow-up scan at 4 weeks revealed no residual enhancement or encephalomalacia...

UNLABELLED: Pituitary abscess is a relatively uncommon cause of pituitary hormone deficiencies and/or a suprasellar mass. Risk factors for pituitary abscess include prior surgery, irradiation and/or pathology of the suprasellar region as well as underlying infections. We present the case of a 22-year-old female presenting with a spontaneous pituitary abscess in the absence of risk factors described previously. Her initial presentation included headache, bitemporal hemianopia, polyuria, polydipsia and amenorrhoea...
