From 120 patients with an homonymous hemianopia 16 experienced complex visual hallucinations in the hemianopic field. The brain lesion was located in the occipital lobe, though damage was not limited to this area. Complex hallucinations appeared after a latent period. They were weak in colour and stereotypical in appearance, which allowed differentiation from visual hallucinations of other caus...

• The optic tract syndrome is characterized by a contralateral, incongruous homonymous hemianopia, contralateral relative afferent pupillary defect (RAPD), and optic atrophy due to retrograde axonal degeneration. • Optic disc pallor often results in a pattern of bowtie atrophy of the eye with temporal field loss and atrophy of the upper and lower poles of the disc of the eye with nasal field lo...

INTRODUCTION Stroke frequently causes homonymous visual field loss. We previously found in a driving simulator that patients with complete homonymous hemianopia had difficulty detecting potential hazards on the side of the field loss. Here we measured the effects of limited paracentral homonymous field loss on detection performance. METHODS Three patients with paracentral homonymous scotomas,...

Posterior cerebral artery (PCA) strokes produce various symptoms. Therefore, the diagnosis is often delayed and patients arrive late for thrombolytic therapy. We report a case of acute isolated PCA occlusion that was successfully treated with endovascular clot aspiration. A 63-year-old man presented with right complete homonymous hemianopia. Diffusion-weighted image (DWI) showed a high-intensit...

PURPOSE To report a case of a 56-year-old male with right homonymous hemianopia. METHODS Retrospective descriptive study of a case report based on information from clinical records, patient observation and analysis of complementary diagnostic tests. RESULTS An asymptomatic 56-year-old male presented to our hospital for a routine ophthalmic examination. The best-corrected visual acuity was 2...
