Filter by:The aim of this study is to develop a less risky, yet effective and more sustainable treatment for retinal vein occlusions than the current commonly used approach of repeated intravitreal triamcinolone acetonide (Kenalog) injections. The types of retinal vien occlusion that are being studied include central (CVRO), hemi-retinal (HRVO),and branch (BRVO) retinal vein occlusion. Niacin, (Nicotinic Acid, not Nicotinamide) a B-vitamin, has lipid lowering and vasodilating properties. The combination of Niacin and Prednisolone Acetate steroid eye drops as a non-invasive treatment approach was developed by the Principal Investigator. The Niacin dilates the retinal vessels, hopefully encouraging earlier collateral vessel formation aimed at bypassing the venous obstruction, thus restoring venous outflow. The Prednisolone Acetate steroid eye drops are aimed at reducing vascular leakage and therefore the macular edema in the eye while the Niacin is taking effect.
Natural evolution of severe central retinal vein occlusion with low visual acuity is very poor. A randomized clinical trial will compare troxerutin and platelet anti-aggregating agents (drug treatment) versus surgery and drug treatment. Surgery will include vitrectomy and radial optic neurotomy. The primary outcome will be vision measured 6 months after surgery.
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.
