the investigation and determination of the significance of neovascularization in the progression of soft tissue sarcoma is currently of increasing clinical importance. microvessel density is the morphologic evidence of neoangiogenesis in the process of malignant progression of sarcomata. this brief review of the markers commonly used in clinical practice was undertaken to determine the validity...

purpose: to image leukocyte adherence to the vascular endothelium and extravasation into surrounding tissues in neovascularized corneas using acridine orange, a selective dna stain, in rats methods: corneal neovascularization was induced by placing two sutures in the cornea of one eye of 12 long-evans rats. one week later, acridine orange (4 mg/kg) was injected via the tail vein and the eyes we...

Ocular neovascularization is a pathological sequel of multiple eye diseases. Based on the anatomical site into which the abnormal neovessels grow, ocular neovascularization can be categorized into corneal neovascularization, choroidal neovascularization, and retinal neovascularization. Each category is intractable, and may lead to blindness if not appropriately treated. However, the current the...

This study investigated the potential role of sirtuin 1 in Müller glial cells in choroidal neovascularization. In the in vitro study, primary Müller glial cells were cultured and treated with resveratrol, a sirtuin 1 activator. Glial fibrillary acidic protein expression and angiogenesis-related gene expression were examined using quantitative polymerase chain reaction and phagocytosis, as a mar...

PURPOSE To investigate the effect of squalamine, an antiangiogenic aminosterol, in an experimental model of iris neovascularization. METHODS Iris neovascularization was created in cynomolgus monkeys by occluding retinal veins with an argon laser and inducing persistent hypotony with a central corneal suture. Twenty-four eyes were treated in three groups. In Group 1, four eyes were injected in...

CLINICAL CASE A patient had bilateral angioid streaks complicated by cicatricial degeneration in the left eye and subfoveal choroidal neovascularization in the right eye. Photodynamic therapy resulted in a favorable response with normalization of the visual acuity and angiographic resolution of the lesions. DISCUSSION The most serious complication of angioid streaks is choroidal neovasculariz...

Both choroidal neovascularization during pregnancy, and choroidal neovascularization following implantation of phakic intraocular lenses have been reported in the literature. To our knowledge, this is the first case reported of a gravid woman developing choroidal neovascularization in an eye with a phakic intraocular lens. A 31-year-old woman became aware of her pregnancy three weeks after plac...

PURPOSE To update the findings from the Choroidal Neovascularization Prevention Trial (CNVPT) with respect to resolution of drusen, incidence of choroidal neovascularization, and visual function. DESIGN A multicenter, randomized, controlled, pilot clinical trial. PARTICIPANTS The 120 patients enrolled in the CNVPT. Patients had signs of choroidal neovascularization or retinal pigment epithe...

GVHD and tumor relapse are fundamental problems in allogeneic HSCT. Recent research has linked neovascularization to GVHD, tumor growth, and graft-versustumor (GVT) activity. Damage of the endothelium by the conditioning regimen provides the initiation stimulus for recruitment of donor-derived endothelial cells and their progenitors. During the early inflammatory phase of GVHD there is consider...
