Filter by:A small percentage of patients with retinal degeneration accumulate fluid in the center of their retina. Previous studies using an oral form of treatment has been successful in decreasing this fluid which improves vision. This study will test the use of a topically applied form of this treatment to the eye to reduce the amount of fluid and improve or preserve vision.
Objective: Diabetic macular edema (DME) is a frequent manifestation of diabetic retinopathy, a leading cause of blindness in the United States. The only proven treatment for DME is laser photocoagulation. Sirolimus has been shown to inhibit the production, signaling and activity of many growth factors relevant to the development of diabetic retinopathy. Therefore, this study will investigate the safety and efficacy of multiple sirolimus injections in patients with DME. Study Population: Eligibility criteria include central macular thickening > 260 microns and visual acuity 20/32 or worse in one or both eyes. Design: Five participants will be enrolled into this open-label pilot study. After receiving a 20 μL (440 μg) subconjunctival injection in the study eye at baseline and Month 2, the participants will be re-evaluated every two months for at least one year for possible additional injections. During follow-up, participants will not undergo re-injection if they show significant clinical improvement or treatment success, defined as no intraretinal fluid or cysts present on optical coherence tomography (OCT) OR 100% reduction in excess retinal thickness over 260 microns on OCT OR no leakage on fluorescein angiography (FA). Beginning at Month 4, participants will be assessed for treatment failure, defined as loss of 15 or more letters of vision compared to baseline at two consecutive visits OR a 50% or greater increase in total retinal thickness as measured by OCT at two consecutive visits. Individual participants deemed treatment failures will continue receiving sirolimus injections, but will be allowed to receive focal laser therapy for any amenable leaking microaneurysms at Month 4. Beginning at Month 6, focal laser therapy will be permitted for both treatment failures and participants who do not meet the criteria of a treatment success. Participants will have the option of continuing treatment until a common termination date of one year. Outcome Measures: The primary outcome is the change in visual acuity in the study eye at six months compared to baseline. Secondary outcomes include changes in visual acuity in the study eye at one year as compared with baseline, changes in retinal thickness as measured by OCT and changes in fluid leakage in the macula as demonstrated by FA at six months, one year and throughout the study period in the study and fellow eyes. Safety outcomes include number and severity of systemic and ocular toxicities, adverse events and infections, and the number of participants withdrawn from study therapy.
The study is designed as a prospective cohort study to assess changes in visual acuity and retinal thickening and surgical complications in subjects undergoing vitrectomy for diabetic macular edema. The study also aims to identify subgroups in which there appears to be a benefit of vitrectomy and subgroups in which vitrectomy does not appear to be beneficial and to obtain data that can be used to plan a randomized trial. Subject will be followed through 2 years, with a primary outcome at 6 months post vitrectomy surgery. The vitrectomy procedure will be performed based on the investigators usual care and is not considered part of the research although the procedure performed will be collected.
Diabetic macular edema is a common cause of visual loss among diabetic patients. Studies have demonstrated the role of vascular endothelial growth factor (VEGF) in the pathogenesis of edema. This study designed to evaluate the effect of Intravitreal injection of a recombinant monoclonal anti-VEGF antibody, Bevacizumab, for treatment of diabetic macular edema.
To evaluate the effectiveness of study drug in improving visual acuity compared to laser treatment in the patients with diabetic macular edema
Injections of medicine into the middle of the eye (intravitreal injections) are commonly used in a multitude of retinal diseases. We are looking for new treatments that may be beneficial in treating retinal disease and improving patients' vision. Infliximab (Remicade) is a genetically engineered antibody against a molecule in the body called TNF-α. It neutralizes the effects of TNF-α by binding to it. Intravenous Infliximab has been used for inflammatory arthritic conditions and Crohn's disease since 1998. We do not know if infliximab injections into the eye are safe. We are performing this pilot study to determine if they can be safe.
This study will evaluate the treatment effect of three doses of the I-vation TA implant (MK0140) in diabetic patients with clinically significant macular edema.
CRFB002D2301: The core study was designed to confirm the efficacy and safety of ranibizumab (0.5 mg) as adjunctive therapy when added to laser photocoagulation and/or mono-therapy in patients with visual impairment due to diabetic macular edema. CRFB002D2301E1: A 24 month open-label extension study for participants who completed the 12 month core study evaluated the long-term safety and efficacy of ranibizumab (0.5 mg) as symptomatic treatment for visual impairment due to diabetic macular edema.
The development or worsening of macular edema following full scatter photocoagulation is a well recognized occurrence. However, there is limited literature in this regard. The purpose of this study is to determine the incidence and extent of macular edema following scatter laser photocoagulation surgery using optical coherence tomography (OCT) in eyes without macular edema prior to scatter laser photocoagulation and to explore whether the incidence and extent of macular edema varies according to the number of sittings included in the treatment regimen. Study eyes will receive one of two types of scatter photocoagulation with results compared through use of OCT and photography images, as well as visual acuity testing.
The purpose of this study is to evaluate the effect of choline fenofibrate on the regression of macular edema in eyes of subjects with type 2 diabetes mellitus (T2DM) presenting with diabetic macular edema (DME)
