Objective:
To assess the clinical effect of argon green laser photocoagulation on diabetic macular edema.
Methods:
Grid macular photocoagulation with argon green laser (lambda = 514 nm), 100-200 microns spot diameter and 0.1-0.2 s duration, was applied to 23 eyes of diabetic macular edema. Panretinal scatter photocoagulations, if needed, were carried out in the later therapy. The mean of the follow-up period was (9.3 +/- 4.1) months. Changes in macular edema and visual acuity as well were observed.
Results:
Complete and partial resolution of macular edema occurred in 21 out of the 23 eyes and visual acuity improved or remained unchanged in 19 out of the 23 eyes.
Conclusion:
Grid macular photocoagulation with argon green laser is effective and relatively safe in the treatment of diabetic macular edema.
