AIM:To compare the effects of yellow(577 nm)subthreshold micropulse laser(SML)and intravitreal(IV)anti-vascular endothelial growth factor(VEGF)treatment in patients with diabetic macular edema(DME)with relatively better visual acuity[best corrected visual acuity(BCVA)≤0.15 log MAR].METHODS:The medical records of 76 eyes of 47 patients underwent IV(0.5 mg)anti-VEGF injection or SML for the DME with relatively better BCVA were *** IV group received three consecutive monthly IV anti-VEGF injections,then were retreated as *** laser treatment group was treated at baseline and 3 mo,and then retreated at 6 and 9 mo if *** participants were followed up for one *** mean BCVA and mean central macular thickness(CMT)values changes over the follow-up were ***:Twenty-four and 23 patients were assigned to the SML and IV subgroups,*** mean number of treatments was 3.64±0.76 in SML group and 5.85±1.38 in IV group(P<0.05).The subgroups were similar with regard to the mean BCVA score at baseline and at the 1st and 3rd months,but the score of SML group was better than that of IV group at the 6th,9th,and 12th months(P<0.05).The decrease in the mean CMT values from baseline values was higher in SML group at the 6th,9th,and 12th months(P<0.05).CONCLUSION:Yellow SML treatment is superior to IV anti-VEGF injection in DME patients with relatively better BCVA for increasing visual acuity and decreasing CMT at 6,9,and 12 *** can be a good alternative first-line therapy for DME with BCVA≤0.15 log MAR.
