Horizontal gaze paresis in hemispheric stroke.

Horizontal gaze paresis in hemispheric stroke.

Of 156 stroke patients prospectively and consecutively evaluated, one-third had a homonymous hemianopia. Of those 52 patients, 46% had a horizontal conjugate gaze paresis at the time of presentation. This gaze paresis was most commonly seen with large hemispheric stroke. The overall prognosis in patients with a gaze paresis was poor. The 30-day case fatality rate was 49% which was significantly...

An isolated horizontal-gaze paresis in a patient with pontine infarction.

Gaze related enhancement of hemispheric blood flow in a stroke patient.

OBJECTIVE A patient with a right posterior cerebral artery territory infarction and a left superior quadrantanopia exhibited improvement on various visual tasks including Goldmann perimetry during extreme right gaze. The phenomenon was investigated by functional imaging of cerebral blood flow. METHODS [(99m)Tc]HMPAO SPECT was carried out while the patient gazed to the right and to the left at...

Horizontal Gaze Palsy: Additional Issues

I read with interest the article by Gautam, et al. [1]. I agree that brainstem tuberculoma can cause nuclear gaze palsy and fascinating neuro-ophthalmological findings. However, I think further clarification regarding pathophysiological mechanism of the gaze palsy may be interesting for the readers. Particularly, two points I want to raise are: difficulty in differentiating pathological lesions...

Mesencephalic bilateral horizontal gaze palsies.

An 81-year-old man with diabetes developed dizziness and markedly limited lateral saccades in both directions (figure, A and C, and video 1 on the Neurology Web site at www.neurology.org), but preserved pursuit and vestibuloocular movements (VOR, accompanied with back-up saccades; videos 2– 4). Diffusionweighted MRI revealed a small high-signal lesion at the ventral paramedian midbrain between ...
