Filter by:The investigators hypothesize that a combination treatment with Avastin and Ozurdex will result in a more rapid improvement of visual acuity compared to the use of Avastin alone.
This study will assess the safety and utility of the new inserter for the administration of ILUVIEN in subjects with diabetic macular edema.
Purpose: To evaluate the effect of intravitreal triamcinolone acetonide (IVTA) on uveitis-associated cystoid macular edema (CME) using high resolution optical coherence tomography (SDOCT) in conjunction with thorough visual function testing. Methods: 28 patients with uveitis-associated CME were examined before intravitreal triamcinolone injection (IVTA) (v1) and at day 1 (v2), week 1 (v3) and month 1 (v4) after injection. Retinal anatomy was evaluated using Cirrus HD-OCT (Carl Zeiss Meditec). Visual function testing consisted of assessing ETDRS distance visual acuity (VA), reading acuity and reading speed using a standardized German-language test (Radner Reading charts), contrast sensitivity using Pelli-Robson Contrast Sensitivity charts and fundus-controlled microperimetry using the MP-1 Microperimeter (Nidek). Here we utilized a cartesian grid consisting of a central locus and three concentric box-shaped stimulation areas. The changes of retinal anatomy over time were compared to the respective outcome of visual function.
The specific aims of the study are to test the following hypotheses: - That there is a difference in change in visual acuity resulting from treatment with intravitreal bevacizumab compared with dexamethasone implant in eyes with advanced macular oedema - That there is a difference in degree of resolution of macular oedema resulting from treatment with intravitreal bevacizumab compared with dexamethasone implant in eyes with advanced macular oedema - That both intravitreal bevacizumab and dexamethasone implants have a manageable and acceptable safety profile in eyes with diabetic macular oedema
This study is designed to explore a more individualized treatment regime based on achievement of disease stability to define a personal optimal treatment interval with ranibizumab in patients with visual impairment due to diabetic macular edema.
The primary purpose of the protocol is to evaluate whether Trientine Hydrochloride, a copper chelator which is an agent that binds with and removes copper, will be effective in minimizing macular edema after cataract surgery in individuals with type 2 diabetes. It is our hypothesis that there will be a reduction in copper-attributed inflammation after surgery resulting a decrease in edema.
This is an open-label, Phase I/II study of intravitreally administered ranibizumab either 0.5-mg and/or 2.0-mg in subjects with clinical, angiographic, and ocular coherence tomography (OCT) evidence of diabetic retinopathy with associated diabetic macular edema following bevacizumab therapy. Thirty patients will be enrolled in this study. Consented, enrolled subjects will receive multiple open-label intravitreal injections of 0.5 mg ranibizumab administered every 30 days (±7 days) for 3 injections during the mandatory treatment phase (Day 0, Month 1, and Month 2). Subjects with complete resolution of diabetic macular edema after 3 intravitreal injections of 0.5 mg ranibizumab will be treated as necessary with 0.5 mg ranibizumab to treat recurrent macular edema for an additional 9 months (12 months from Day 0). The intent is to administer additional ranibizumab treatment if there is evidence of disease activity documented on OCT (e.g., intra-retinal fluid, subretinal fluid and/or cystic changes). Subjects with residual diabetic macular edema following 3 intravitreal injections of 0.5 mg ranibizumab will be receive 3 intravitreal injections of 2.0 mg ranibizumab administered every 30 days (±7 days) for 3 injections at the Month 3, Month 4, and Month 5 study visits. Beginning at the Month 6 study visit, subjects with complete resolution of diabetic macular edema following 3 intravitreal injections of 2.0 mg ranibizumab will treated as necessary with 2.0 mg ranibizumab injections only to treat recurrent macular edema for an additional 6 months (12 months from Day 0). Subjects with residual diabetic macular edema following 3 consecutive intravitreal injections of 2.0 mg ranibizumab will be treated as necessary with 2.0 mg ranibizumab to treat persistent or recurrent macular edema for an additional 6 months (12 months from Day 0). Focal photocoagulation or intravitreal triamcinolone may be administered at the physician's discretion as an adjunct to ranibizumab injections beginning at Month 6 through Month 12 of the study. All subjects will make monthly visits for 12 months for evaluation of safety and efficacy. All subjects will have their first injection of ranibizumab on Day 0 and undergo a safety visit one week (±2 days) after the first injection. At subsequent visits, the subject will have a safety evaluation at the monthly scheduled follow-up visit prior to any intravitreal injection. Subjects will be contacted by the site personnel 1-2 days after each injection to elicit reports of decreased vision or pain or unusual new ocular symptoms in the study eye.
The purpose of the study is to determine where a sustained steroid delivery system (Ozurdex,Allergan) is safe and effective to treat Cystoid Macular Edema in diabetic patients after Cataract Surgery
This was a Phase IV multicenter, randomized, open-label study, with masking of the vision examiner, of the efficacy and safety of intravitreal ranibizumab 0.5 mg in subjects with macular edema following Branch Retinal Vein Occlusion (BRVO) or Central Retinal Vein Occlusion (CRVO).
An epiretinal membrane is scar tissue on the retina that can cause blurring and distortion of vision and lead to swelling, or macular edema. Despite surgery to remove the scar tissue(membrane peeling), residual swelling of the retina may continue to interfere with vision. In this study the investigators will inject an implantable steroid device into the back, fluid-filled portion of the eye. Steroids have been found to decrease the swelling in the retina. Ozurdex™ is an implantable steroid. Once implanted, Ozurdex™ is slowly dissolved by the vitreous gel that fills the eye, releasing the steroid. The steroid drug delivery system in this study, known as Ozurdex™ has been FDA-approved by the US Food and Drug Administration (FDA) for decreasing swelling due to another condition in the eye. This study will help to find out whether or not this device Ozurdex™ is also effective for reducing the swelling of the retina in patients who have already had surgery to remove scar tissue on the retina.
