prospective randomised controlled trial comparing sub-threshold micropulse diode laser photocoagulation and conventional green laser for clinically significant diabetic macular oedema
Comparison of masked tests conducted in two centers
Laser light condensation of threshold micro-pulse diode (MPDL)
Conventional green laser coagulation (CGL)
In the treatment of clinically significant diabetic edema (CSMO). Methods: Fifty-Three patients. 84 eyes)
CSMO with diabetes was randomly assigned to MPDL (nu200a=u200a44)or CGL (nu200a=u200a40)
Study on modified early treatment of diabetic kidney disease (ETDRS)protocol.
Treatment and re-treatment after baseline
If required, treatment is allowed at or after a 4 month visit.
The parameters for attention include the best corrected vision (BCVA)
, Color fundus photos using optical coherent tomography, central retinal thickness (OCT)
, Visual contrast sensitivity to the Pelli-Robson chart, and the presence of laser scars visible at baseline and 4 and 12 months.
The main result was BCVA at 12 months.
Results: all patients completed 12 months of follow-up
Increased after baseline treatment.
At 0, 4 and 12 months, there was no statistically significant difference in BCVA, contrast sensitivity, and retinal thickness between the two laser modes.
We found laser scars in the CGL than in the sub-
Threshold Method (MPDL).
Laser scars were found during the 12 months of 13 years. 9% of the MPDL-
Treated eyes compared to 59 eyes. 0% of the CGL-treated eyes (p
