The aim of the study is to evaluate the relationship between Humphrey visual field progression and peripheral vascular endothelial function in patients with open-angle glaucoma (OAG), assessed by noninvasive endothelium-dependent flow-mediated vasodilation (FMD).Forty OAG patients, among which 22 had normal-tension glaucoma (NTG) and 18 had primary open-angle glaucoma (POAG) were enrolled. Each...

Purpose. To investigate blood pressure and heart rate variability in patients with primary open-angle glaucoma (POAG) to detect disturbed blood pressure regulation. Methods. Thirty-one patients with POAG (mean age 68 ± 10 years) and 48 control subjects (mean age 66 ± 10 years) were included in a prospective study. Continuous blood pressure and heart rate were simultaneously and noninvasively re...

The evolution and characteristics of diabetic rubeosis were studied in 33 eyes, and the following vascular abnormalities were found: (1) Dilated leaking capillaries around the pupil; (2) irregular or slow filling of the radial arteries; (3) superficial arborising newly formed vessels, usually starting in the chamber angle; and (4) dilatation and leakage of the radial vessels either before or af...

AIM To determine the prevalence of preglaucomatous angle-closure disease in central Myanmar. METHODS A population-based survey of inhabitants >or=40 years in the Meiktila District was carried out; 2481 subjects were identified, 2076 participated and 2060 underwent gonioscopy of at least one eye. Eyes with angles traditionally described as "occludable" were recorded as primary angle-closure su...

We present the therapeutic options and functional results in patients with plateau iris (syndrome or configuration) in consecutive case series. Material and method: Our study included newly diagnosed patients with acute angle closure by "plateau iris" (configuration or syndrome), between June 2016 and April 2017. Series of 8 consecutive patients met the inclusion criteria, all being females. Al...

background and objective: vascular endothelial growth factor (vegf) and its receptors (vegf-r1 and r2) are major regulators of angiogenesis. this study was designed to assess serum levels of vegf and vegf-r1 and their prognostic significance in newly diagnosed childhood acute leukemia. materials and methods: for this purpose, vegf and vegf-r1 were determined using enzyme linked immuno-sorbant a...

PURPOSE To determine whether cardiovascular risk factors distribution differ between primary open-angle glaucoma (POAG) and control subjects. To assess the strength of this association in POAG. To analyze the most frequent pathology in this group of patients for a better selection of medical treatment. METHODS Observational cross-sectional study in patients with a diagnosis of POAG. Fifty gla...

Introduction: Dynamic contrast-enhanced (DCE-) MRI has become a valuable tool in the assessment of tumors and in the evaluation of the effects of treatment. Kinetic modeling with two or three (including tumor vascular component vp) compartments is commonly used to measure the parameter K, a first order rate constant that describes tumor perfusion and vascular permeability. In its calculation, t...
