Active clinical trials for "Retinal Vein Occlusion"

Purpose: To determine whether a fluocinolone acetonide sustained drug delivery implant is effective in the treatment of retinal vein occlusion that has caused persistent macular edema and decreased visual acuity. Hypothesis: A fluocinolone acetonide sustained drug delivery implant will be a safe and effective method to treat patients with macular edema and decreased vision from retinal vein occlusion.

The RAVE (Rubeosis Anit-VEgf) trial, utilizes monthly intravitreal Ranibizumab (Lucentis) injections for 9 months to see if total VEGF blockade will prevent neovascular glaucoma and eliminate the need for panretinal photocoagulation in patients with ischemic central retinal vein occlusion.

The purpose of this study is to determine whether Niacin, a B vitamin, may act as a vasodilator to encourage earlier formation of collateral blood vessels that may serve to bypass the obstructed vein in the eye. The topical steroid eye drops are aimed at reducing swelling in the retina, until the collateral vessels have a chance to develop.

This study will evaluate the safety and effectiveness of a new formulation of triamcinolone acetonide for the treatment of retinal blood vessel disorders. Triamcinolone is a steroid drug that decreases inflammation and scarring and is routinely used to treat eye inflammation or swelling. The commercially available form of this drug is associated with potentially harmful side effects thought to be due to preservatives in the preparation. This study will use a formulation that does not contain these potentially harmful preservatives. Preliminary findings from other studies suggest that injection of steroids in the eye can reduce retinal thickening and improve vision. However, they may also cause mild discomfort and lead to vision-threatening conditions. The effects of the drug on the conditions under study in this protocol are not known. Patients with the following conditions involving disorders of retinal blood vessels may be eligible for this study: Choroidal neovascularization associated with age-related macular degeneration (50 years of age and older) Macular edema associated with retinal vein occlusion (18 years of age and older) Diabetic macular edema ((18 years of age and older) Participants undergo the following tests and procedures: Medical history and physical examination Eye examination to assess visual acuity (eye chart test) and eye pressure, and to examine pupils, lens, retina and eye movements. The pupils will be dilated with drops for this examination. Fluorescein angiography to evaluate the eye's blood vessels. A yellow dye is injected into an arm vein and travels to the blood vessels in the eyes. Pictures of the retina are taken using a camera that flashes a blue light into the eye. The pictures show if any dye has leaked from the vessels into the retina, indicating possible blood vessel abnormality. Indocyanine green angiography to identify feeder vessels that may be supplying abnormal blood vessels. This procedure is similar to fluorescein angiography, but uses a green dye and flashes an invisible light. Optical coherence tomography to measure retinal thickness. This test shines a light into the eye and produces cross-sectional pictures of the retina. These measurements are repeated during the study to determine if retinal thickening is getting better or worse, or staying the same. Stereoscopic color fundus photography to examine the back of the eye. The pupils are dilated with eye drops to allow examination and photography of the back of the eye. Triamcinolone acetonide injection to treat the eye. A numbing eye drop, an antibiotic eye drop, and an injected antibiotic are put in the eye before triamcinolone acetonide is injected into the eye's vitreous (jelly-like substance inside the eye). After the injection, the patient lies on his or her back for 30 minutes. An antibiotic eye ointment is used for 2 days following treatment. Blood tests to measure liver and kidney function. Patients return to the clinic for follow-up visits 1, 4, and 7 days, and 1 month after the first treatment. Patients whose condition does not improve after 3 months do not receive any more injections, but return for eye examinations at least once a year for 3 years. Patients whose condition improves with treatment return for follow-up visits 6 and 9 months after the first injection and then every 6 months for 2 more years. At each visit, a determination is made whether another injection is needed. After each repeat injection, patients return for follow-up visits at 1, 4, and 7 days after the injection.

This prospective non-randomized open-label interventional study aimed to evaluate feasibility in regard to potential efficacy and safety of triamcinolone acetonide (TA) injected in the suprachoroidal space (SCS) as a promising therapeutic route that provides a better bioavailability, longer sustained duration of action, and thus improved patients' compliance for the treatment of macular edema due to retinal vein occlusion (RVO).

This is a Phase III, multicenter, randomized, double-masked, active comparator-controlled, parallel-group study evaluating the efficacy, safety, and pharmacokinetics of faricimab administered by intravitreal (IVT) injection at 4-week intervals until Week 24, followed by a double-masked period of study without active control to evaluate faricimab administered according to a personalized treatment interval (PTI) dosing regimen in patients with macular edema due to central retinal vein occlusion (CRVO) or hemiretinal vein occlusion (HRVO).

To investigate the efficacy of laser photocoagulation combined with ranibizumab intravitreal injection in macular edema (ME) secondary to branch retinal vein occlusion (BRVO) in long term.

In central retinal vein occlusion (CRVO) a blood clot blocks the venous outflow of the entire retinal circulation. This leads to retinal and vitreous hemorrhages, retinal edema and neovascularization. The development of a microneedle and surgical stabilizer made it possible to perform a prolonged (10 minutes) retinal vein cannulation with infusion of Ocriplasmin. Ocriplasmin has the advantage over tissue Plasminogen Activator (tPA) that it already is an active enzyme and a strong fibrinolyticum. This study aims to investigate the feasibility and safety of local intravenous Ocriplasmin for CRVO.

This is an open-label, multicenter, extension study of intravitreally administered ranibizumab in two cohorts. The first cohort (reported separately under FVF3426g, NCT00379795) enrolled subjects with primary or recurrent Choroidal Neovascularization (CNV) secondary to Age-Related Macular Degeneration (AMD) who completed the treatment phase of a Genentech sponsored study (FVF2598g (NCT00056836), FVF2587g (NCT00061594), or FVF2428g (NCT00056823)). The second cohort (reported here) enrolled subjects with macular edema secondary to Retinal Vein Occlusion (RVO) who completed the 6-month treatment and 6-month observation phases (12 months total) of a Genentech sponsored study (FVF4165g (NCT00486018) or FVF4166g (NCT00485836)). Patients were enrolled within 14 days of completion of the previous study.

The aim of the trial is to evaluate the efficacy and safety of intravitreal injections of ranibizumab for the treatment of macular edema due to BRVO if the re-treatment regimen is guided by morphological macular changes detected by OCT compared to re-treatment according to SmPC defined re-treatment criteria (in case of increase of CRT and concomitant decrease of BCVA).
