Filter by:A prospective multicenter study comparing patients with CRVO amd secondary macular edema treated with ranibizumab versus sham. Safety and efficacy will be evaluated. Patients will be randomized in a 1:1 ratio to one of the two arms. 32 patients, 6 months follow up. There will be monthly visits with injection the first three months and subsequently new injection if present edema.
Treatment of macular edema secondary to central retinal vein occlusion is more effective with combined therapy of bevacizumab and triamcinolone than bevacizumab alone.
Growing evidence shows that altered blood flow plays a major role in many vision-threatening diseases including glaucoma, diabetic retinopathy, age-related macular degeneration, Central Retinal Vein Occlusion, and Branch Retinal Vein Occlusion. Optical coherence tomography, an established imaging technique use for eye exam in clinical ophthalmology, provides high-resolution cross sectional images of the retina and has increased our ability to understand many eye diseases.
The ROVO study is a prospective, placebocontrolled and randomised study designed to evaluate the effect of radial optic neurotomy in central vein occlusion, versus triamcinolone acetonide. 240 patients with a visual acuity < 0.5 Snellen will be randomised. Patients are treated with either RON, or a single intravitreal injection of 4 mg triamcinolone acetonide, or a placebo treatment - a "sham" injection of intravitreal triamcinolone. Patients will be examined regularly over a period of one year. Best corrected visual acuity for far and near, as well as clinical examinations, fluorescein- and indocyanine green angiograms, optical coherence tomography, and perimetry, are performed pre- and postoperatively.
The ATORVO study is designed to determine whether atorvastatin (Lipitor) can improve vision, when compared to placebo
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.
The purpose of this study is to determine whether ranibizumab will be effective in reducing if not eliminating the macular edema associated with the disease, central retinal vein occlusion (CRVO).
Patients with Central Retinal Vein Occlusion will undergo vitrectomy, a small needle of about 71 micron will enter a branch retinal vein and TPA will be injected into the obstracted vein.
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.
