[Comparative study of efficacy of focal photocoagulation in diabetic macular edema according to the wave length used]

Abstract

We have studied the efficacy of the different wavelengths in the treatment of focal macular edema of diabetic retinopathy. For this purpose, we evaluated the evolution of visual acuity and that of the eye fundus, six months after the treatment in 20 eyes of 20 patients treated with blue-green argon laser, in 20 eyes of 20 patients treated with monochromatic green argon laser and in 20 eyes of 20 patients treated with yellow dye laser. The best results were obtained in the group treated with yellow Dye laser after six months of follow-up (p less than or equal to 0.05). The efficacy on the reabsorption of exudates was similar for the three types of laser.
