To provide use of Anecortave Acetate Sterile Suspension of 15mg for a series of five patients with rubeosis iridis. Rubeosis iridis refers to neovascularization of the iris. It is caused by a number of conditions which include, but are not limited to severe diabetic retinopathy, central retinal vein occlusion, chronic inflammation, and infection. Anecortave acetate is an angiostatic, experimental drug that is being tested to prevent the growth of blood vessels under the retina in patients with age-related macular degeneration (AMD). Therefore, it is logical to apply the usage of Anecortave to patient’s with rubeosis iridis in order to reduce the neovascularization stimulus and cause the regression of the abnormal iris vessels.
The purpose of this study is to provide compassionate use of anecortave acetate sterile suspension of 15 mg for a series of five patients as a means to control diabetic retinopathy.
The purpose of this study is to determine if intravitreal injection of Vitrase (ovine hyaluronidase) clears vitreous hemorrhage
The purpose of this study is to determine if intravitreal injection of Vitrase (ovine hyaluronidase) clears vitreous hemorrhage
The purpose of this study is to assess the efficacy of intravitreous injections of Vitrase to induce posterior vitreous detachment(PVD) in subjects with moderate to severe non-proliferative diabetic retinopathy.
To compare the progression of diabetic retinopathy in type 2 diabetic patients with mild-to-moderate diabetic retinopathy treated with insulin glargine vs NPH human insulin.
Phase III study comparing monthly octreotide i.m. in comparison to no additional treatment in patients with proliferative diabetic retinopathy after lasercoagulation.
Recurrent vitreous hemorrhage after vitrectomy for complications of diabetic retinopathy is a common occurrence. The hemorrhage may appear within the first few weeks after surgery or months later. This complication may delay visual rehabilitation significantly and sometimes requires additional procedures or surgery, jeopardizing previous successful operation. The causes of bleeding are diverse. While evidence suggests fibrovascular proliferation from the sclerotomy sites or in the vitreous base may be an important source of recurrent vitreous hemorrhage, other origins of hemorrhage exist including lysed clot from residual vitreous skirt, injured retinal vessels from surgery, and incompletely removed fibrovascular tissues. The latter three conditions may be the major sources of early postoperative vitreous hemorrhage. We have shown that peripheral retinal cryotherapy along with cryo treatment at the sclerotomy sites may effectively reduce the incidence of fibrovascular proliferation at the inner surface of sclerotomy sites and prevent the late-onset recurrent vitreous hemorrhage. However, many patients still experience disturbing vitreous hemorrhage within the first two to three weeks after post-operative transient clear-up of the vitreous. We hypothesize that gas bubble within the vitreous cavity may mechanically temponade the fragile retinal vessels, and concentrate the coagulation factors in the vitreous cavity, allowing the integrity of vessel walls gradually recovers and thus preventing the occurrence of early postoperative recurrent vitreous hemorrhage. To test this hypothesis, a clinical study was undertaken to investigate the effect of long-acting gas infused into the vitreous cavity at the end of diabetic vitrectomy in the prevention of recurrent vitreous hemorrhage.
The most common ocular disease in patients with diabetes, diabetic retinopathy, is present in approximately 40% of diabetic patients; about 8% of diabetic patients have vision threatening diabetic retinopathy. Although intensive control of blood glucose has been shown to reduce the development and progression of diabetic retinopathy, intensive control of glucose is usually not achieved in clinical practice.
