Active clinical trials for "Diabetic Retinopathy"

The purpose of this study is to determine the efficacy and safety of intravitreous ranibizumab treatment versus sham injections for prevention of high-risk DR.

Panretinal photocoagulation (PRP) has been the standard treatment for Proliferative diabetic retinopathy (PDR) since the Diabetic Retinopathy Study demonstrated its benefit nearly 40 years ago,but PRP has inevitable adverse effects on visual function. Intravitreal injection of vascular endothelial growth factor(VEGF) can induce short-term regression of retinal neovascularization(NV). The purpose is to assess and compare the efficacy and safety between intravitreal injection of conbercept and PRP.

This is a study aiming to assess the efficacy and safety of Keluo Xin capsule in patients with moderately severe to severe nonproliferative diabetic retinopathy (NPDR). Two-thirds of participates will receive Keluo Xin capsules while other one third will receive placebo.

Retinal nonperfusion drives vision-threatening complications such as pathological neovascularization, which can lead to neovascular glaucoma, vitreous hemorrhage, or tractional retinal detachments and macular edema in diabetic retinopathy. Thus, decreasing nonperfusion area with aid of anti-VEGF agents might be a useful way to prevent deteriorating course of diabetic retinopathy. The main purpose of this study is to determine the efficacy of intravitreal aflibercept injection in improvement of retinal nonperfusion and identify associated factors in patients with nonproliferative diabetic retinopathy with moderate retinal nonperfusion.

Diabetes mellitus is a major and growing problem worldwide with many known micro and macrovascular complications. According to International Diabetes Federation, there were 285 million adults diagnosed with diabetes in 2010 and expected to increase to 439 million adult in 2030. It is a leading cause of chronic kidney disease (CKD) followed by hypertension, glomerulonephritis, and cystic kidney disease. Renal impairment patients metabolize and excrete drugs differently from patients with normal renal function and hence only limited number of oral hypoglycemic agent (OHA) available for them. One of the choices is sodium glucose co-transporter-2 inhibitor (SGLT2i) which is now widely used. Apart from its nephroprotective advantage, it also has additional benefit on cardiovascular and renal function based on EMPA-REG OUTCOME trial. One of the examples of SGLT2i is Empagliflozin (JARDIANCE) tablet, which has FDA U.S. Approval in 2014. It acts by reduces renal reabsorption of filtered glucose and lowers the renal threshold for glucose, thus increases urinary glucose excretion. It can cause osmotic diuresis, which may lead to intravascular volume contraction. Apart from its additional cardiovascular and nephroprotective effect, SGLT2 inhibitor might have additional protective effect to the eye. Nowadays, optical coherence tomography angiography (OCT-A) has emerged as one of a non-invasive methods to study the microvasculature of the retina and choroid. Many studies had discussed regarding-pre clinical changes present on OCT-A in patients without clinical diabetic retinopathy. These pre-clinical changes includes capillary dropout, microaneurysm, neovascularization, venous beading and enlargement of fovea avascular zone. However, there are minimal data and publications on different type of diabetic CKD with OCT-A parameters in diabetic patients. The purpose of this study is to determine the effect of short term SGLT2 inhibition on OCT-A parameters (fovea avascular zone (FAZ) size, vessel density and perfusion density) in diabetic CKD.

The purpose of the investigator's study is to evaluate the efficacy and safety profile of the pro re nata (PRN) regimen to 12 months by using intravitreal dexamethasone implant in eyes with treatment-naive diabetic macular edema patients.

The complicated schedules for administering topical steroid eye drops combined with forgetfulness and physical difficulties instilling the drops may compromise compliance; which in turn could increase the risk for secondary complications such as PME post-cataract surgery, especially in a high-risk diabetic population. Dextenza, a sustained- release steroid insert, could help preclude adherence difficulties and provide better bioavailability, being as effective as, or more effective than steroid drops in preventing PME. The aim of this study is to assess the incidence of PME in diabetic patients undergoing cataract surgery when comparing the Dextenza insert to topical prednisolone acetate 1% drops.

Laser photocoagulation has become the treatment of choice in PDR. Laser photocoagulation has become the treatment of choice in PDR. The aim is to destroy a substantial portion of the peripheral retina in order to reduce the angiogenic stimulus (decrease the difference between oxygen demand and the administration). Their effectiveness is determined by the extent of destruction of the retina (2.4).

Diabetic retinopathy (DR) is a common complication of diabetes mellitus that leads to loss of vision and blindness among working age adults. An ideal adjunctive agent for treating DR hence should be polymorphic and possess antiangiogenic, neuroprotective, anti-inflammatory, anti-oxidant as well as anti-ischaemic properties.Natureceuticals Sdn Bhd assessed the efficacy of core ingredient of Nuvastatic™, Lanctos 75™ for the treatment and management of the diabetic retinopathic condition.
