Damage to the visual cortex or the geniculostriatal pathways could cause homonymous visual field (VF) defects at the contralateral side of the lesion. In clinical practice, it is known that the VF defects are gradually recovered over months on the cases. We report a case with recovered homonymous hemianopia following an infarction in the visual cortex by positron emission tomography (PET) with ...

Introduction. Embolization into the systemic circulation through persistent foramen ovale is known as paradoxical embolization. Coexistence of embolism with pulmonary thromboembolism rare and it requires detailed examination. The objective this study was to present an unusual case stroke that complicated by occurrence thromboembolism, thrombosis superior mesenteric artery, arterial infarction n...

A 2½-year-old girl developed a bilateral occipital infarct following severe gastroenteritis with bilateral vision of light perception. Evaluations for sickle cell anemia, hemolytic anemia and coagulopathies were negative. Cortical blindness is an uncommon but dramatic complication of gastroenteritis, hence the need of prompt hydration and other supportive measures to avoid irreversible visual l...

BACKGROUND Bilateral stroke following radiofrequency catheter ablation is an unusual complication and may result in bilateral altitudinal visual field defects. Bilateral altitudinal visual field defects usually result from prechiasmal pathology causing damage to both retinas or optic nerves and rarely from bilateral symmetric damage to the post chiasmal visual pathways. CASE PRESENTATION A 48...

BACKGROUND AND PURPOSE Decreased cerebral blood flow with an increased oxygen extraction fraction, the so-called misery perfusion syndrome, suggests a vulnerability to reduction in cerebral perfusion pressure and a tendency to develop cerebral infarction. It is uncertain, however, whether the infarct would occur in the brain region specifically exhibiting this condition. CASE DESCRIPTION We r...

OBJECTIVE To assess various aspects of visual function at school age in children with neonatal cerebral infarction. PATIENTS AND METHODS Sixteen children born at term, who had cerebral infarction of perinatal onset on neonatal magnetic resonance imaging (MRI) were assessed using a battery of visual tests. This included measures of crowding acuity (Cambridge Crowding Cards), stereopsis (TNO te...

purpose: to describe the clinical and photographic features of a patient who developed left homo-nymous hemianopia due to right occipital lobe hemorrhage after ingestion of sildenafil citrate (viagra). case report: a 63-year-old man was referred for acute blurred of vision in both eyes five hours after taking 50 mg viagra® (sildenafil citrate). visual field testing revealed left homonymous hemi...

Cortical blindness as a sequelae of trauma has been reported in the literature but its pathophysiology remains unknown. We report a case of transient post-traumatic cortical blindness as a result of bilateral occipital lobe infarcts in a multiply injured patient after a 6-storey fall from height. We discuss the possible aetiologies for our patient’s condition and reviewed the relevant literatur...
