CLEAR SIGHT: A Trial of Non-Mydriatic Ultra-Widefield Retinal Imaging to Screen for Diabetic Eye Disease

In this study, the investigators are addressing a significant and expanding "care-gap" question for patients with diabetes who are at risk for diabetic retinopathy (DR). DR is a major cause of impaired health-related quality of life in Ontarians through visual loss including blindness. Because the prevalence of DM in Ontario ...

Phase N/A

Day Regimes of CONbercept on CytokinEs of PDR Patients Undergoing Vitrectomy - Trial (CONCEPT)

Proliferative diabetic retinopathy (PDR), characterized by neovascularization and brous proliferation, is a severe and common complication of diabetes mellitus (DM). Persistent vitreous hemorrhage (VH) caused by neovascularization and tractional retinal detachment (TRD) caused by brous proliferation can lead to permanent vision loss or even blindness, which are the most common ...

Phase

Correlation Between Macular Ischemia and Peripheral Ischemia in Patients With Diabetes

The contribution of OCT- angiography (OCT-A) allows to consider, in a more or less long term, a drastic reduction in the use of fluorescein angiographies in diabetic retinopathy. The accuracy of the analysis of the vascularization of retinal layers of the posterior pole of the eye by the OCT-A , ...

Phase N/A

Diabetic Retinopathy: Effects of Melatonin Treatment on Visual Functions and Circadian Rhythm

This study evaluates the effect of melatonin 4 mg on circadian rhythm and visual function of patients with diabetes mellitus. Half of the patients will receive melatonin (arm-1) and the other half will receive placebo (arm-2), both groups in 3 weeks. After a week of washout, the patients will cross ...

Phase

Prevention of Macular Edema In Patients With Diabetic Retinopathy Undergoing Cataract Surgery

Diabetic retinopathy patients who are at risk of developing macular edema (defined as 30 % increase from pre-operative baseline in central subfield macular thickness) within 90 days following cataract surgery. Diabetic patients are defined as those who have either Type 1 or Type 2 diabetes. The patients must have either ...

Phase

Role of Obstructive Sleep Apnea Syndrome in the Occurrence of Diabetic Retinopathy in Type 2 Diabetes.

Diabetic retinopathy (DR) is the most common visual complication of diabetes. Risk factors for developing DR are diabetes duration, glycemic control, and hypertension. The prevalence ranges from 17 to 61% according to the diabetes duration. Obstructive sleep apnea syndrome (OSAS) is very frequent in Type 2 Diabetes population, reaching a ...

Phase N/A

Treatment of Diabetic Macular Edema With Aflibercept in Subjects Previously Treated With Ranibizumab or Bevacizumab

This study is an investigator initiated interventional study for subjects with diabetic macular edema that have been previously treated with bevacizumab or ranibizumab. Intravitreal aflibercept 2mg will be given until OCT (ocular coherence tomography) demonstrates an absence of fluid. Continued intravitreal aflibercept 2mg will then take place every 2 months ...

Phase

Perifoveal Vascular Network Assessed by OCT-Angiography in Type I Diabetes Mellitus

Diabetic retinopathy (DR) is the leading cause of blindness in type 1 Diabetes Mellitus (DM) patients, as a consequence of impaired blood flow in the retina. Optical coherence tomography angiography (OCT-A) is a newly developed, non-invasive, retinal imaging technique that allows detection of perfused and non perfused areas of the ...

Phase N/A

Genetic Markers and Proliferative Diabetic Retinopathy

In a previous study (2011), investigators demonstrated a statistically significant relation between the Endothelial Lipase(EL) c.584C>T polymorphism and the occurrence of diabetic retinopathy in 396 french patients with diabetes type 2 (DT2) with a longitudinal follow-up. Secondly (2014) in a subgroup of 287 DT2 patients, investigators showed the impact of ...

Phase N/A

Thermal Screening for Early Diabetic Peripheral Neuropathy (DPN)

This study focuses on further development and testing of a microvascular functional imaging system, a computer-based system for screening thermal video images, designed to detect biomarkers of diabetic peripheral neuropathy (DPN). Additionally, severity levels of diabetic retinopathy (DR) will be compared with those of DPN. All participants in this study ...
