Abstract:
Objective To observe the changes in the subfoveal choroidal thickness(SFCT)of children and adoles-cents with different refractive states using optical coherence tomography angiography.Methods A total of 171 children and adolescents were followed.They were divided into the lower primary school group(6-8 years old),upper primary school group(9-11 years old),and junior high school group(12-14 years old)according to their age at the time of en-rollment.Dioptric examinations(including best corrected visual acuity,diopter,intraocular pressure,corneal curvature,axial length and SFCT)were performed,data collection was conducted twice in half a year(initial examination and review after half a year),and the eyeball parameters and changes in eyeball parameters after half a year among all groups were compared.Results The axial length and SFCT of subjects had significant differences among all groups(both P＜0.05).In children and adolescents,the axial length gradually lengthened and SFCT gradually thickened with age,while intraocular pressure and corneal curvature were not associated with age(both P＞0.05).In the initial examination and review after half a year,there was no significant difference in intraocular pressure,corneal curvature and SFCT of subjects with differ-ent refractive states in all groups(all P＞0.05),while the axial length of myopic subjects was greater than that of non-my-opic subjects in all groups(all P＜0.05).In the review after half a year,the SFCT of non-myopic subjects in the lower pri-mary school group and upper primary school group was significantly thickened(P＜0.001,P=0.003),while there was no significant difference in SFCT of myopic subjects in all groups compared with the value half a year ago(all P＞0.05).The axial length of all subjects showed a positive correlation with the SFCT in the initial examination and review after half a year(r=0.354,0.228,P＜0.05).Conclusion Myopia affects the increase in SFCT in children and adolescents.
