摘      要：BACKGROUND Non-proliferative diabetic retinopathy(NPDR)poses a significant challenge in diabetes management due to its microvascular changes in the *** photocoagulation,a conventional therapy,aims to mitigate the risk of progressing to proliferative diabetic retinopathy(PDR).AIM To compare the efficacy and safety of multi-spot vs single-spot scanning panretinal laser photocoagulation in NPDR *** Forty-nine NPDR patients(86 eyes)treated between September 2020 and July 2022 were *** were randomly allocated into single-spot(n=23,40 eyes)and multi-spot(n=26,46 eyes)*** outcomes,including bestcorrected visual acuity(BCVA),central macular thickness(CMT),and mean threshold sensitivity,were assessed at predetermined intervals over 12 *** reactions were also *** Energy levels did not significantly differ between groups(P0.05),but the multi-spot group exhibited lower energy density(P0.05).CONCLUSION While energy intensity and safety were comparable between modalities,multi-spot scanning demonstrated lower energy density and showed superior short-term improvements in BCVA and CMT for NPDR patients,with reduced laser-induced damage.
