- Primary Outcome Measures
Name Time Method Macular thickness changes after multispots patter photocoagulation in both groups.<br>Retinal thickness measurements are performed with SD-OCT (Spectralis; Heidelberg Engineering, CA, USA). Scans are performed in fast high resolution pattern, 1024 x 526 resolution. All scans will be reviewed for the accuracy and manually adjusted by one investigator.[6 months]
- Secondary Outcome Measures
Name Time Method Visual acuity changes after multispots patter photocoagulation in both groups.<br>Visual acuity will be recorded in ETDRS letters measured at 6-meter charts.[6 months]
