[Visual field defects in high myopic glaucoma compared with moderate myopic glaucoma].

Purpose: To demonstrate the visual field defects characteristic of high myopic glaucoma eyes.

Methods: Eighty-one high myopic glaucoma eyes (< or = -8 diopter(D)) and eighty moderate myopic glaucoma eyes(-3 D approximately -6 D) from patients under the age of 60 were enrolled in this study. Visual acuity, Mean Deviation (MD) of Humphrey visual field analyzer (HFA) central 30-2 program, and the pattern of central visual field defect especially at the early stage of glaucoma (MD > or = -10 dB) were compared between high and moderate myopic groups.

Correlation of angiographic circulation time and cerebrovascular reserve by acetazolamide-challenged single photon emission CT.

Background And Purpose: Although cerebral circulation time (CCT) is one of the main parameters in cerebral blood flow measurements, its clinical significance is controversial. To assess the importance of CCT by using a nondiffusible indicator, we studied the relationship between angiographic CCT and cerebrovascular reserve.

Methods: Twenty-eight patients, each with a unilateral occlusive lesion in the internal carotid artery or middle cerebral artery, were examined.

Imaging of distal internal carotid artery by ultrasonography with a 3.5-MHz convex probe.

Background And Purpose: Conventionally, carotid ultrasonography has been performed with a 7.5-MHz linear probe to evaluate the extracranial internal carotid artery (ICA). However, usually only the carotid bulb or proximal portion of the ICA can be evaluated.

Association of plasma homocysteine concentration with atherosclerotic carotid plaques and lacunar infarction.

Background And Purpose: Higher plasma total homocysteine (tHcy) levels have been associated with carotid atherosclerosis and cerebral infarction in whites. However, data regarding such associations are limited for Asians. This study examined associations between tHcy levels and severity of carotid atherosclerosis in Japanese subjects.
