Active clinical trials for "Macular Edema"

The purpose of this study is to determine whether denufosol tetrasodium (INS37217) Intravitreal Injection is well tolerated and has the potential to treat uveitis associated macular edema.

The purpose of this study was to evaluate the efficacy and safety of brolucizumab in treatment of patients with macular edema (ME) secondary to central retinal vein occlusion (CRVO).

To assess the biomarker profile in diabetic macular edema patients in response to intravitreal aflibercept injection. Patients with diabetic macular edema who meet study requirements will receive monthly intravitreal injections of aflibercept as approved by FDA for a period of 6 months. A small quantity of fluid will be removed from the vitreous at each injection for laboratory evaluation of biomarkers present before, during and after treatment with aflibercept.

This Phase 3, multicenter, randomized, masked, controlled, parallel group study is designed to demonstrate that suprachoroidal (SC) CLS-TA administered with intravitreal (IVT) anti-VEGF agent in subjects with treatment naive RVO is superior to IVT anti-VEGF agent used alone.

The PROTECT2 pilot study is a single cohort prospective study to gather pilot data and finalize operational details of the main study. The PROTECT2 main study is a prospective randomized controlled multi-center three group clinical trial. The primary endpoint is the percentage of participants in each study group obtaining a qualified eye examination within 12 months of their enrollment in the study.

This study is conducted to select the THR-687 dose level (Part A of the study) and to assess the efficacy and safety of the selected dose level compared to aflibercept (Part B of the study).

This Phase 3 study will evaluate the efficacy, durability, and safety of KSI-301 compared to aflibercept in participants with treatment-naïve DME.

The Early Treatment Diabetic Retinopathy Study (ETDRS) group founded guidelines for treating patients with clinically significant diabetic macular edema (DME) with focal/grid macular laser photocoagulation. Since then, macular laser, and steroids, were the main therapies for the treatment of DME until anti-vascular endothelial growth factors (anti-VEGF) drugs were developed after a growing body of scientific evidence implicated VEGF in the pathophysiologic process of DME. Anti-VEGF drugs have been implicated in the treatment of DME. VEGF has been shown to play an important role in the occurrence of increased vascular permeability in DME. VEGF levels are significantly higher in patients with DME and extensive leakage than in patients with minimal leakage. Many studies such as Diabetic Retinopathy Clinical Research [DRCR] Network studies, RESTORE Study, RISE and RIDE Research Group, and The BOLT Study have supported the use of anti-VEGF agents in the treatment of DME with better visual outcomes using anti-VEGF injections alone or in combination with other treatments. Several ocular complications of intravitreal anti-VEGF injections have been reported including endophthalmitis, cataract, and retinal detachment. The different effects on macular perfusion between different anti-VEGFs have yet to be fully concluded with mixed conclusions that it increases or decreases or has no effect on perfusion of the macula in response to Anti-VEGF treatment. In many of these studies, however, patients with more ischemic retinas were not included. Retinal ischemia is a vital factor determining the diabetic retinopathy progression and prognosis. Optical coherence tomography angiography (OCTA) detects blood flow by analyzing signal decorrelation between two sequential OCT cross-sectional scans at the same location. As it detects the movements of red blood corpuscles within the vessels, compared to the stationary retinal surroundings, which will result in signal disparity and imaging The split-spectrum amplitude-decorrelation angiography (SSADA) algorithm improves the signal to noise ratio. OCTA is considered a reliable tool in the detection and quantification of macular ischemia in diabetics. In this study, the investigators aim to compare the effect of repeated intravitreal injections of ranibizumab and bevacizumab on the perfusion of different capillary layers in the macula of diabetic patients using OCTA.

This study seeks to evaluate the effect of the intravitreal 0.7mg dexamethasone implant on central macular thickness and visual acuity in those patients with persistent macular edema after pars plana vitrectomy for epiretinal membrane.

The purpose of this study is to evaluate the effect of dexamethasone intravitreal implant (Ozurdex) in combination with pars plana vitrectomy and membrane peeling for idiopathic epiretinal membrane (ERM).
