摘　　要：目的:通过多光谱视网膜屈光地形图(MRT)测量4~10岁远视眼儿童周边视网膜相对屈光度(RPRE),并分析不同程度远视眼儿童RPRE分布的特点。方法:病例对照研究。连续性纳入2021年9月至2022年9月在长沙湘江爱尔眼科医院门诊就诊的4~10岁的远视眼儿童60例(120眼),根据睫状肌麻痹后的等效球镜度(SE)分为轻度远视组(LH,0.50 D≤SE<3.00 D)49眼,中度远视组(MH,3.00 D≤SE<5.00 D)46眼,高度远视组(HH,SE≥5.00 D)25眼。采用MRT测量每眼视网膜不同区域的RPRE并得出其平均值,结果记录包括:总离焦值(TRDV)、0°~15°离焦值(RDV-15)、15°~30°离焦值(RDV-30)、30°~45°离焦值(RDV-45)、上方离焦值(RDV-S)、下方离焦值(RDV-I)、鼻侧离焦值(RDV-N)、颞侧离焦值(RDV-T)。采用Pearson相关分析不同远视度数与视网膜周边屈光度的关系,通过单因素方差分析不同偏心度RPRE的差异,采用配对样本t检验分析对比上方及下方离焦值,鼻侧及颞侧离焦值。结果:从低度远视到高度远视,屈光度与TRDV呈负相关(r=-0.35,P<0.001)。3组间在0°~15°、15°~30°、30°~45°范围的离焦值差异均有统计学意义(F=6.51,P=0.002;F=6.14,P=0.003;F=6.83,P=0.002),其中0°~15°及15°~30°范围内,HH组离焦值均小于另外2组,即HH组的近视性离焦更大。4~10岁远视眼上方离焦值小于下方,均为近视性离焦,差异有统计学意义(t=-3.44,P=0.001);颞侧离焦值小于鼻侧,颞侧为近视性离焦,鼻侧为远视性离焦,差异有统计学意义(t=-4.01,P<0.001)。结论:4~10岁远视眼儿童视网膜总的离焦值为近视性离焦,且随着远视度数的增加,近视性离焦更大;在视网膜偏心度30°范围内,4~10岁高度远视儿童近视离焦值要大于中低度远视儿童;上方离焦量小于下方,颞侧离焦量小于鼻侧,鼻侧为远视性离焦。Objective:The relative peripheral refractive errors(RPRE)of hyperopic children aged 4-10 years were measured by multispectral refractive topography(MRT),and the characteristics of RPRE distribution in different degree hyperopic children were analyzed.Methods:In this case-control study,a total of 60 hyperopic children aged 4-10 years were included,which was conducted from September 2021 to September 2022 at the Changsha Xiangjiang Aier Eye Hospital.Based on the spherical equivalent(SE)after ciliary muscle paralysis,49 eyes were divided into the following groups:low hyperopia group(LH,0.50 D≤SE˂3.00 D),moderate hyperopia group(MH,3.00 D≤SE˂5.00 D)and high hyperopia group(HH,SE≥5.00 D).The mean values of RPRE in different regions of retina were measured by MRT.The results were recorded as follows:total refraction difference value(TRDV),0°-15°refraction difference value(RDV-15),15°-30°refraction difference value(RDV-30),30°-45°refraction difference value(RDV-45),superior refraction difference value(RDV-S),inferior refraction difference value(RDV-I),nasal refraction difference value(RDV-N),temperior refraction difference value(RDV-T).Pearson correlation was used to analyze the relationship between different degrees and peripheral retinal diopters,and the differences of different eccentricity RPRE were analyzed by univariate ANOVA.Paired sample t-test to analyze and compare superior and inferior refraction values,nasal and temperior refraction values.Results:There was a negative correlation between diopter and TRDV from low hyperopia to high hyperopia(r=-0.35,P<0.001).There were significant differences among 0°-15°,15°-30°and 30°-45°(F=6.51,P=0.002;F=6.14,P=0.003;F=6.83,P=0.002).In the range of 0°-15°and 15°-30°,the TRDV of the HH group was smaller than that of the other two groups,indicating that the myopic defocus of the HH group was the greatest.The superior defocus value of hyperopic eyes aged 4-10 years is smaller than the inferior defocus value,which is myopic defocus with a statistically
