[Clinical observation on argon green laser in the treatment of diabetic macular edema].
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.


CONCLUSIONS
Grid macular photocoagulation with argon green laser is effective and relatively safe in the treatment of diabetic macular edema.
