چکیده

The ultrastructure of old neovascular preretinal membranes was examined in both eyes of a patient with proliferative diabetic retinopathy treated in one eye with photocoagulation. Membranes in both eyes consisted of a matrix rich in mature collagen surrounding viable new vessels and "ghost vessels." Viable vessels of different calibers frequently showed endothelial fenestrae bridged by diaphragms. Occasionally tight junctions between endothelial cells appeared altered. Fenestrae and incompetent junctions may account for the characteristic "leakiness" of newly formed vessels.

Comparison of axial length of the eye in patients with diabetic retinopathy and non diabetics

Introduction: To compare the axial length of globe in patients with diabetic retinopathy with that in normal population and to evaluate its role in the progression of diabetic retinopathy. Methods: 150 patients with diabetic retinopathy in both eyes were compared with 150 age and sex matched non diabetic patients, referred to Motahari retina clinic of Shiraz, during fall 2000. The axial length...

Association of the VEGF gene with proliferative diabetic retinopathy but not proteinuria in diabetes.

Diabetic retinopathy and nephropathy cause significant morbidity in patients with diabetes. Vascular endothelial growth factor (VEGF) is a potent angiogenic and vascular permeability factor and is implicated in both of these diabetes complications. We previously reported transfection studies showing the VEGF -460 and VEGF +405 polymorphisms to increase basal VEGF promoter activity by 71% compar...

Association of CXCL12 and CXCR4 Genes Polymorphism with Proliferative Diabetic Retinopathy in Diabetic Patients

Introduction: Patients with diabetes are prone to develop complications related to the retina. So far, several genes have been reported in connection with the progression of retinopathy, and a group of these genes is genes involved in angiogenesis. CXCL12 and CXCR4 genes are among the most important genes in this path, which have been less studied and investigated. The aim of this study was to ...

VEGF localisation in diabetic retinopathy.

AIM To determine the staining pattern of vascular endothelial growth factor (VEGF) at different stages of diabetic retinopathy (including post-laser photocoagulation) and to compare staining in excised fibrovascular and fibrocellular (non-diabetic) preretinal membranes. METHODS Immunohistochemical localisation of VEGF, using antibodies raised against VEGF165 and VEGF121,165,189, was carried o...

Erythropoietin as a retinal angiogenic factor in proliferative diabetic retinopathy.

BACKGROUND Although vascular endothelial growth factor (VEGF) is a primary mediator of retinal angiogenesis, VEGF inhibition alone is insufficient to prevent retinal neovascularization. Hence, it is postulated that there are other potent ischemia-induced angiogenic factors. Erythropoietin possesses angiogenic activity, but its potential role in ocular angiogenesis is not established. METHODS ...
