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.
Our aim is to compare patient comfort when using the 532 nanometer (green) wavelength laser to the 577 nanometer (yellow) wavelength laser during pan retinal photocoagulation to treat patients with diabetic retinopathy. Secondary outcome measures will be power (mW) required to achieve gray-white retinal burns and duration of treatment.
This is a prospective, randomized, active control, two-arm parallel, double-blind, monocenter phase IV clinical trial. The trial compares empagliflozin to glimepiride in patients with type 2 diabetes mellitus in addition to standard of care treatment. Patients with type 2 diabetes mellitus who are between 18 and 80 years of age will be recruited for the clinical trial and randomly allocated to either receive empagliflozin or glimepiride. The assumption of the study is that empagliflozin slows down diabetic retinopathy progression rate and thus a lower microaneurysm formation rate compared to subjects treated with glimepiride by substantially decreased cellular glucotoxicity will be achieved.
This study is a multi-armed protocol designed to evaluate the safety and efficacy of two different combinations of nutritional supplements (study drug) (Glauco-Health and Glauco-Select) chosen for their potential to protect retinal ganglion cells against oxidative stress, low-grade inflammation, and mitochondrial dysfunction in patients with open-angle glaucoma and diabetic retinopathy. Oxidative stress and retinal cellular dysfunction will be measured using a Retinal Metabolic Analyzer (RMA) in this randomized, single center, double masked study. Patients with glaucoma will be divided into three treatment arms randomized to receive either Glauco-Health, Glauco-Select, or placebo.
This is a phase I/II open label, randomized, interventional clinical trial. Study eyes will receive one preoperative intravitreal aflibercept injection (IAI) <21 days but >7 days prior to vitrectomy and one intraoperative IAI at end of surgery followed by randomization in a 1:1 ratio into either 4 mandatory postoperative q4weeks IAI followed by mandatory q8 weeks IAI for 52 weeks follow-up (q8 week Group) or 2 mandatory postoperative q4weeks IAI followed by mandatory q16 weeks IAI for 52 weeks follow-up (q16 week Group).
Diabetes affects 30.3 million people or 9.3% of the population of the United States. Results of a study by the Eye Diseases Prevalence Research Group reveal that 40% of diabetes patients have some degree of diabetic retinopathy (DR) and that as many as 8% have severe, vision-threatening forms of DR. Early laser photocoagulation in high-risk proliferative diabetic retinopathy (PDR) has been shown to decrease the relative risk of vision loss by as much as 52%. Injections of anti-VEGF agents preserve and improve vision in people with PDR and/or diabetic macular edema. Despite effective treatment however, tens of thousands of people with diabetes are going blind each year largely because they don't undergo annual screening for retinopathy. Currently, less than 50%-60% of people with diabetes have a yearly eye exam and there may not be enough eye specialists to see the balance. The IDx-DR System is intended for use by health care providers to automatically detect more than mild diabetic retinopathy (mtmDR) in adults (22 years of age or older) diagnosed with diabetes who have not been previously diagnosed with diabetic retinopathy. IDx-DR is indicated for use with the Topcon NW400.
To compare immediate laser pan-retinal photocoagulation (PRP) treatment of severe or very severe non proliferative diabetic retinopathy (NPDR) stage versus deferral of treatment until the appearance of any proliferative diabetic retinopathy (PDR) in rural and urban patients in China. Interview data from some patients and survey data from ophthalmologists in the study hospitals will help determine acceptability of early treatment, and how to overcome barriers to increased use of this option.
In Brazil 10% of the adult population has diabetes. Of these, 39.0% are undiagnosed, at risk for developing complications such as diabetic retinopathy (DR). Due to the increasing prevalence of diabetes and high percentage of patients with uncontrolled disease, cost-effective tools are needed with focused attention on diabetes prevention and management in the current health system. The automatic retinopathy detection can enlarge the screening, reducing the workload and costs compared to manual image graders.
The main objectives of this observational study were to describe outcomes, monitoring and treatment patterns of patients with diabetic macular edema in routine clinical practice who are either treatment naïve patients or previously treated patients. The total study population was evaluated as well as the two subgroups (previously treated patients and treatment naïve patients). This study was designated to answer French Health Authority (HAS Haute Autorité de Santé) requirements.
