Safety and Effectiveness Study of 532nm Laser Subthreshold Panretinal Photocoagulation for Severe NPDR

Overview

This randomized, parallel controlled, clinical-trial aims to evaluate the therapeutic efficacy of 532nm laser partially subthreshold panretinal photocoagulation with PASCAL endpoint management function for severe non-proliferative diabetic retinopathy.

This randomized, parallel controlled, clinical-trial aims to evaluate the therapeutic efficacy of 532nm laser partially subthreshold panretinal photocoagulation with PASCAL endpoint management function for severe non-proliferative diabetic retinopathy : (1)To evaluate therapeutic effect of 532nm laser partially subthreshold panretinal photocoagulation with PASCAL endpoint management function for severe non-proliferative diabetic retinopathy; (2)To compare side effect of 532nm laser partially subthreshold panretinal photocoagulation with PASCAL endpoint management function on retina with traditional visible endpoint panretinal photocoagulation.
