DIABETIC MACULAR EDEMA


Study: Evaluation of Vitrectomy for DME

Sponsor: Diabetic Retinopathy Clinical Research Network

Number of sites: 29

Status: Recruiting

Purpose: To provide information on the following outcomes in eyes with DME that undergo vitrectomy: visual acuity, retinal thickening, resolution of traction (if present), surgical complications; to identify subgroups in which there appears to be a benefit of vitrectomy and subgroups in which vitrectomy does not appear to be beneficial; to obtain data that can be used to plan a randomized trial.
