Summary

This randomized, parallel controlled, clinical-trial aims to evaluate the therapeutic efficacy and safety of 577nm micropulse laser photocoagulation for diabetic macular edema compared with 532 subthreshold laser photocoagulation.

Conditions

Interventions

DEVICE

577-MPL

Device for 577nm micropulse treatment of the diabetic macular edema with the following parameters:100 microns spot size,5% duty cycle of 0.2 seconds,power is tested on micropulse mode and then reduce power to 50% of visible

DEVICE

532-SLP

Device for 532nm subthreshold treatment of the diabetic macular edema, by decomposing a subthreshold short pulse, with 10 milliseconds, 100 microns, and power(100-1000mW) adjusted according to patient's diopter transparency and pigmentation
