Clinical Trial Summary

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.


Clinical Trial Description

China now has the world's largest number of diabetic persons. Population studies show that only 10% of Chinese rural-dwellers with DR receive therapy. The current standard approach to treatment of DR often requires patients to return for multiple examinations over years, before they reach trial-proven criteria for treatment. This long process is ill-suited to support good compliance with care in low-resource settings. Our recent published review suggests that earlier PRP treatment, which could reduce the burden of compliance, may be clinically effective and cost effective, but the current evidence base is insufficient to make a firm recommendation. ;
