Acute loss of vision and alcoholic intoxication suggests the possibility of methanol poisoning. In this report we describe an alcoholic patient who complained of blindness after recovering from alcoholic pancreatitis and delirium tremens. Visual acuity was severely impaired and fundoscopy revealed florid bilateral cotton wool spots and a cherry red spot at the right macula. Such appearances hav...

Papilledema and raised intracranial pressure have been reported in association with Guillain-Barre syndrome. Papilledema is usually asympotomatic or associated with mild visual field defects, without any visual loss. The cerebrospinal fluid protein is usually reported to be high. A case of a 35 year old lady is reported, who presented with headache, diplopia and progressive visual loss in both ...

Transient visual loss due to cerebro-ocular vascular disease is a common symptom. The purpose of this paper is to present a unified terminology of the monocular vs. binocular or homonymous types. Lack of proper identification may lead to mis-diagnosis and improper management of these entities. Monocular blurred vision must be investigated since its origin is so commonly due to atherosclerosis o...

While there have been numerous studies of the vestibular system in mammals, less is known about the brain mechanisms of vestibular processing in humans. In particular, of the studies that have been carried out in humans over the last 30 years, none has investigated how vestibular stimulation (VS) affects cortical oscillations. Here we recorded high-density electroencephalography (EEG) in health...

Cerebral blindness is defined as bilateral loss of vision secondary to disruption in the visual pathways posterior to the lateral geniculate nuclei [1]. Cortical blindness, a particular type of cerebral blindness, is defined as the total loss of vision in the presence of normal pupillary reflexes and in the absence of ophthalmological disease [2], resulting from bilateral lesions of the striate...

We present a case of a patient with Anton's syndrome (i.e., visual anosognosia with confabulations), who developed bilateral occipital lobe infarct. Bilateral occipital brain damage results in blindness, and patients start to confabulate to fill in the missing sensory input. In addition, the patient occasionally becomes agitated and talks to himself, which indicates that, besides Anton's syndro...

We report a patient with a bilateral optic anterior ischemic neuropathy as an extrahepatic complication of a chronic hepatitis C (HCV) infection. The patient presented with a bilateral visual acuity loss and bilateral optic disc oedema. The optic neuropathy was associated with a sudden increase in the viral HCV load after a recent liver transplantation. The stop of the calcineurin inhibitor had...
