Background:
Occlusion of the retinal vessels leading to retinal ischaemia and hypoxia is an important element in the pathophysiology of the major vision threatening diseases in the Western World. The hypoxic areas release vasodilating factors that induce vasodilatation in adjacent retinal areas in
Retinal nonperfusion drives vision-threatening complications such as pathological neovascularization, which can lead to neovascular glaucoma, vitreous hemorrhage, or tractional retinal detachments and macular edema in various retinal vascular diseases including diabetic retinopathy and retinal vein
To investigate the response of retinal vessel diameters to lucentis treatment in patients with BRVO and to correlate these changes with changes in functional outcome after 3 months.
Pilot study in patients scheduled for intravitreal anti-VEGF (Lucentis™) treatment with BRVO
30 patients with BRVO
Diabetes mellitus is the most common endocrine disease in developed countries, with prevalence estimates ranging between 2 to 5% of the world's population. Diabetic retinopathy and diabetic macular edema are common microvascular complications in diabetic patients and may lead to decreasing of visual
Introduction:
The endothelial growth factor (VEGF), was identified for the first time in the liquid of ascitis in Guinean pigs (6,7). It is a dimeric glycoprotein, naturally expressed in epithelial and tumor cells (1). It's over expression during retinal hypoxia (9), has been implied in the genesis
