Active clinical trials for "Diabetic Retinopathy"

To conduct a precision study to assess the microperimetry function of the Spectral OCT/SLO. The study will assess variability across measurements taken by three different operator-device configuration across clinical sites, variability between subjects within a given operator-device configuration, and variability within a subject for a single operator-device configuration.

To evaluate if intravitreal Ozurdex can reduce the incidence of recurrent vitreous hemorrhage after primary pars plana vitrectomy (PPV) in patients with proliferative diabetic retinopathy (PDRP).

Contrast sensitivity is a tool use to evaluate the visual function in all patients. It can be modified by different pathologies or by age. The purpose of this study is to identify the changes that could be in relationship with the course of diabetic retinopathy comparing with diabetic patient without retinopathy and in patients with diabetic macular edema so if it is a difference, research for therapeutic strategies to improve it in this patients.

The main objective of this study is to characterize and correlate diabetic macular edema (DME), i.e. increased retinal thickness, measured by Optical Coherence Tomograph (OCT), and retinal visual function. The secondary objectives of this study are the analysis and characterization of DME progression over time (between two visits), and the comparison of OCT data obtained with different devices. The results of this study will be used exclusively for scientific purposes.

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.

Macular hole in proliferative diabetic retinopathy with fibrovascular proliferation may have unique features. Internal limiting membrane peeling facilitates hole closure only in cases with shallow macular detachment. Final vision is associated with preoperative visual acuity and degree of macula elevation.

The purpose of this study is to validate and characterize phenotypes of diabetic retinopathy (DR) progression based on available clinical data (demographic, systemic and ophthalmic data).

To evaluate the relation of retinal microvascular characteristics to subclinical cardiovascular disease, clinical disease, and their risk factors in the Multi-Ethnic Study of Atherosclerosis (MESA) cohort.

The object of this study is to investigate the damage to the retinal nerve fiber layer (RNFL) and ganglion cell complex layer (GCL+) in diabetic patients without retinal microangioma as detected by fundus fluorescein angiography (FFA) and to determine the kind of nerve damage more likely to indicate early injury.

To present the clinical characteristics and rational treatment of macular hole (MH) after the diabetic vitrectomy (DV) in patients with proliferative diabetic retinopathy (PDR).
