We compared the capillary blood-cell velocity in the fingertips of 30 patients with high-tension glaucoma, 30 patients with normal-tension glaucoma, and 30 control subjects by nailfold capillaroscopy. There were no measurable differences in the morphologic findings. The blood-flow velocity, however, was reduced significantly in the patients with(More)
Previous studies indicated calcium channel blockers to be of some help for normal-tension glaucoma patients. The present study evaluates the effect of magnesium, a 'physiological calcium blocker', in 10 glaucoma patients (6 with primary open-angle glaucoma, 4 with normal-tension glaucoma). All patients had a digital cold-induced vasospasm. Magnesium (121.5(More)
In a number of patients with etiologically unexplained visual field loss, a vasospastic syndrome could be found with the help of a capillaroscopic local cooling test on the fingers. In the patients with proven vasospastic syndrome, the visual field defects were increased after a cold water test and decreased after a therapy with calcium entry blockers.(More)
It is assumed that the ocular circulation may be involved in the vasospastic syndrome and patients with vasospasm have visual field defects that are neither ophthalmologically nor neurologically explainable. A retrospective study showed that 20 mg sustained-release nifedipine treatment given orally may be helpful in these cases. There was a marked(More)
In a number of patients with etiologically unexplained visual field loss, a vasospastic syndrome was found with the aid of capillaroscopic local cooling test on the fingers. After therapy with calcium entry blockers the visual field of the patients with vasospastic syndrome underwent a marked and statistically significant improvement. The control group(More)
There is clinical and experimental evidence that both increased intraocular pressure and disturbed circulation are involved in the pathogenesis of glaucomatous damage. Among the many factors discussed, decreased blood pressure and vasospasm are the most important, and these factors may, at least in part, be therapeutically influenced. The basic underlying(More)
