Filter by:There is evidence from a variety of animal studies that choroidal blood flow is under neural control. Recent results in humans indicate that a light/dark transition is associated with a short lasting reduction in choroidal blood flow. Several observations indicate that the changes in choroidal perfusion are triggered at least in part by neural mechanisms. Particularly, we have shown that during unilateral dark/light transition both eyes react with choroidal vasoconstriction strongly indicating a neural mechanism for blood flow regulation. Investigation of changes in choroidal blood flow during light/dark transition may represent an interesting approach to study neural dysregulation at the level of the eye in patients with IDDM. Accordingly, the hypothesis of reduced choroidal blood flow responses to a light/dark transition in patient with IDDM will be tested. This response in choroidal blood flow will be correlated to parameters of diabetic neuropathy and diabetic retinopathy.
The purpose of this study is to determine whether systemic administration of darbepoetin alpha results in the progression or regression of diabetic macular edema.
To evaluate the effectiveness of study drug in improving visual acuity compared to laser treatment in the patients with diabetic macular edema
This is a randomized, open-label Phase II study evaluating the safety and efficacy of intravitreally administered ranibizumab 0.5mg in subjects with Proliferative Diabetic Retinopathy experiencing post- Panretinal Photocoagulation (PRP) macular edema.
The purpose of this study is to determine the safety and efficacy of Vitreosolve in diabetic retinopathy patients.
Background: to evaluate the 3-month efficacy of a single dose of intravitreal bevacizumab on the progression of severe non proliferative diabetic retinopathy, proliferative diabetic retinopathy and active photocoagulated diabetic proliferative by evaluation of ischemic areas and regression of retinal and disc neovasculrization. Methods: 40 patients were enrolled in a prospective, interventional study. Patients were treated with intravitreal bevacizumab 0.1ml (0.25mg). We evaluated visual acuity, neovascularization leakage points, capillary closure ischemic areas and macular edema by clinical examination and fluorescein angiography. A clinical examination was performed at baseline and days 1,14 and 30. Active leakage points were measured by fluorescein angiography at 30 days.
Laser photocoagulation has become the treatment of choice in PDR. Laser photocoagulation has become the treatment of choice in TMD. The aim is to destroy a substantial portion of the peripheral retina in order to reduce the angiogenic stimulus (decrease the difference between oxygen demand and the administration). Their effectiveness is determined by the extent of destruction of the retina (2.4).

The purpose of this study is to determine if treatment with infliximab improves macular edema which is refractory to laser photocoagulation in patients with diabetes.
Diabetic Retinopathy is the leading cause of blindness in the world. Previous studies have documented beneficial effects of physiologic administration of pulsatile insulin on a variety of diabetic complications such as nephropathy, hypertension, glycemic control, etc. Similar pathogenetic mechanisms have been postulated for diabetic retinal disease. This study examines the effect of pulsatile insulin on patients with varying stages of diabetic retinal disease.
