Purpose:
|
The aim of the present study is to investigate the effect of subthreshold diode laser micropulse, in comparison with conventional laser photocoagulation, on the treatment of the diabetic macular edema
|
Methods:
|
Sixty-eight eyes from 68 patients were studied, and the patients were divided randomly into two groups. In the first group, subthreshold diode laser micropulse photocoagulation was employed to treat macular edema, while conventional laser photocoagulation was performed on the eyes of the second group. Central macular thickness, central macular volume, and best corrected visual acuity were measured before, 2 and 4 months after intervention, and the results were compared with each other
|
Results:
|
The mean of central macular thickness was 357.3 and 354.8 microns before the treatment in group 1 and group 2, respectively, and decreased significantly to 344.3 and 349.8 after 4 months. This decline was considerably different in both groups (P=0.001). The mean of central macular volume significantly dropped in group 1 (P=0.003), but it was similar to the pretreatment in group 2 (P=0.31) after 4 months. The best corrected visual acuity notably improved in group 1 (P?0.001), but it was constant in the other group (P=0.38).
|
Conclusion:
|
Subthreshold diode laser micropulse is more effective than conventional laser photocoagulation in reducing CMT and CMV and improving visual acuity in patients with diabetic macular edema. It can be a good substitute for the conventional laser photocoagulation, which is a more complicated laser therapy, in order to treat diabetic macular edema.
