Background: Systemic high dose application of magnesium leads to relaxation of vasospasm in small vessels. In normal pressure glaucoma patients vasospasm might be one of the major patho-genetic factors. Some investigations report on a neuroprotective action of oral magnesium. Aim of the present study was to examine the effect of oral magnesium on ocular blood flow and visual 相似文献

Introduction: The Confoscan 3 is a scanning slit corneal confocal microscope. The scanning slit principle allows only the light from a thin plane of the cornea to be focused on an extremely sensitive CCD camera. The non applanating 40X immersion objective produces corneal frames 340mm×255 mm wide and 5mm thick. The analysed area is small but the details provided, allows the in vivo study of the cellular and extra cellular structures. 相似文献

The cell morphology of corneal endothelium in 84 mice with experimental traumatic cataract was investigated with stained corneal buttons. In the experimental group, the boundaries between adjacent corneal endothelial cells were significantly distorted, some cell boundaries manifested degenerative changes that led to coalescence of the cells. The mean density and mean area of endothelial cells of the controls showed significant difference from those of the experimental group during the 12 weeks of observation. The density of endothelial cells decreased from 3312±337/mm~2 of the control group to 2944±418/mm~2 in the group of partially opaque lenses and 2713±472/mm~2 in the group of totally opaque lenses. Meanwhile, the area of endothelial cells and the coefficient of variation also significantly changed correspondingly, and the degree of damage in the corneal endothelium correlated with the degree of the lens opacity. 相似文献

Purpose: To discuss the value of a new method of grading quantitatively the amount of disc damage in patients with glaucoma Methods: The Disc Damage Likelihood Score (DDLS) employs 9 stages of damage based on the width of the neuroretinal rim or the circumferential extent of absence of rim, adjusted for the size of the optic disc. We report the results of studies regarding re- 相似文献

No considerable difference between efficiency of topical car-boanhydrase inhibitors was detected during comparison of their hypotensive effect after single usage in healthy volunteers and glaucoma patients (40 participants). Maximal hypotensive effect occurred in four hours after study started and average IOP decreasing was one percent from primary level. When using during 相似文献

Purpose: To compare endoscopic cyclophotocoagulation (ECP) and Ahmed drainage implant in the treatment of refractory glaucoma. Methods: 68 eyes with refractory glaucoma were randomized prospectively to either ECP or Ahmed tube shunt implantation, always performed by a single surgeon. Eyes that were included were pseudophakic with a history of at least one tra-beculectomy with an antimetabolite, and a visual acuity better 相似文献
