Abstract:
Objective To compare the blood flow perfusion area in different retinal vascular plexuses between adults and children using swept-source optical coherence tomography angiography(SS-OCTA)and explore the correlation of the retinal blood flow perfusion area with spherical equivalent(SE)and axial length(AL).Methods A total of 112 partici-pants,including 58 children(116 eyes,aged 8-13 years)and 54 adults(108 eyes,aged 18-30 years),were recruited from Eye Hospital,Wenzhou Medical University from December 2020 to December 2024.Based on SE,these children and adults were further divided into the emmetropia(-0.50<SE ≤+0.50 D),low myopia(-3.00<SE≤-0.50 D),and moderate myopia(-6.00<SE≤-3.00 D)groups.SS-OCTA was used to acquire the perfusion area data across retinal vascular layers.The inner vascular network of the retina was subdivided into the peripapillary radial vascular network,su-perficial vascular plexus(SVP),middle vascular plexus(MVP),and deep vascular plexus(DVP).The blood flow perfu-sion areas across retinal vascular layers were compared between adults and children.Pearson correlation analysis was per-formed to assess the correlation of the blood flow perfusion areas across retinal vascular layers with AL and SE in adults and children,respectively.Results SE was negatively correlated with AL in both adults and children(r=-0.781 and-0.667,respectively;both P<0.001).The total inner retinal perfusion area was negatively correlated with AL in both adults and children(r=-0.239 and-0.299,respectively;both P<0.05).In children,the perfusion area in the peripapil-lary radial vascular network,SVP,and DVP was negatively correlated with AL(r=-0.443,-0.315,and-0.220,respec-tively;all P<0.05).In adults,the perfusion area in SVP,MVP,and DVP was negatively correlated with AL(r=-0.243,-0.230,and-0.364,respectively;all P<0.05).Adults with low/moderate myopia exhibited a significantly larger perfu-sion area in the peripapillary radial vascular network compared with children with corresponding myopia levels,and the differences were statistically significant(both P<0.001).Conclusion There were significant differences in the perfu-sion area of the peripapillary radial vascular network between adult and pediatric myopic patients.AL showed the strongest correlations with the perfusion area of the peripapillary radial vascular network in adults and the perfusion area of DVP in children,respectively,suggesting distinct effects of retinal vascular layers at different stages of ocular growth.
