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.

Detailed description

1. To evaluate the efficacy of 577nm micropulse laser photocoagulation with grid/focal treatment for diabetic macular edema. 2. To investigate influence of 577nm micropulse laser photocoagulation on structure and function of macula compared with 532nm subthreshold laser photocoagulation.

Conditions

• Diabetic Macular Edema

Interventions

Type	Name	Description
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
