To compare relative peripheral refraction (RPR) in Chinese school children with different refractive errors using multispectral refraction topography (MRT).
A total of 713 eyes of primary school children [172 emmetropia (E), 429 low myopia (LM), 80 moderate myopia (MM), and 32 low hypermetropia (LH)] aged 10 to 13y were analyzed. RPRs were measured using MRT without mydriasis. MRT results showed RPR at 0-15° (RPR 0-15), 15°-30° (RPR 15-30), and 30°-45° (RPR 30-45) annular in the inferior (RPR-I), superior (RPR-S), nasal (RPR-N), and temporal (RPR-T) quadrants. Spherical equivalent (SE) was detected and calculated using an autorefractor.
There were significant differences of RPR 15-30 between groups MM [0.02 (-0.12; 0.18)] and LH [-0.13 (-0.36; 0.12)] (<0.05), MM and E [-0.06 (-0.20; 0.10)] (<0.05), and LM [-0.02 (-0.15; 0.15)] and E (<0.05). There were also significant differences of RPR 30-45 between groups MM [0.45 (0.18; 0.74)] and E [0.29 (-0.09; 0.67)] (<0.05), and LM [0.44 (0.14; 0.76)] and E (<0.001). RPR values increased from the hyperopic to medium myopic group in each annular. There were significant differences of RPR-S between groups MM [-0.02 (-0.60; 0.30)] and E [-0.44 (-0.89; -0.04)] (<0.001), and LM [-0.28 (-0.71; 0.12)] and E (<0.05). There were also significant differences of RPR-T between groups MM [0.37 (0.21; 0.78)] and LH [0.14 (-0.52; 0.50)] (<0.05), LM [0.41 (0.06; 0.84)] and LH (<0.05), and LM and E [0.29 (-0.10; 0.68), <0.05]. A Spearman's correlation analysis showed a negative correlation between RPR and SE in the 15°-30° (=0.005), 30°-45° (<0.05) annular (=0.002), superior (<0.001), and temporal (=0.001) quadrants.
Without pupil dilation, values for RPR 15-30, 30-45, RPR-S, and T shows significant differences between myopic eyes and emmetropia, and the differences are negatively correlated with SE.
使用多光谱屈光地形图（MRT）比较不同屈光不正的中国学龄儿童的相对周边屈光（RPR）。
分析了10至13岁小学生的713只眼[172只正视眼（E）、429只低度近视眼（LM）、80只中度近视眼（MM）和32只低度远视眼（LH）]。在不散瞳的情况下使用MRT测量RPR。MRT结果显示在下方（RPR-I）、上方（RPR-S）、鼻侧（RPR-N）和颞侧（RPR-T）象限中0-15°（RPR 0-15）、15°-30°（RPR 15-30）和30°-45°（RPR 30-45）环形区域的RPR。使用自动验光仪检测并计算等效球镜度（SE）。
MM组[0.02（-0.12；0.18）]与LH组[-0.13（-0.36；0.12）]之间的RPR 15-30存在显著差异（<0.05），MM组与E组[-0.06（-0.20；0.10）]之间存在显著差异（<0.05），LM组[-0.02（-0.15；0.15）]与E组之间存在显著差异（<0.05）。MM组[0.45（0.18；0.74）]与E组[0.29（-0.09；0.67）]之间的RPR 30-45也存在显著差异（<0.05），LM组[0.44（0.14；0.76）]与E组之间存在显著差异（<0.001）。在每个环形区域中，RPR值从远视组到中度近视组增加。MM组[-0.02（-0.60；0.30）]与E组[-0.44（-0.89；-0.04）]之间的RPR-S存在显著差异（<0.001），LM组[-0.28（-0.71；0.12）]与E组之间存在显著差异（<0.05）。MM组[0.37（0.21；0.78）]与LH组[0.14（-0.52；0.50）]之间的RPR-T也存在显著差异（<0.05），LM组[0.41（0.06；0.84）]与LH组之间存在显著差异（<0.05），LM组与E组[0.29（-0.10；0.68），<0.05]之间存在显著差异。Spearman相关性分析显示，在15°-30°（=0.005）、30°-45°（<0.05）环形区域（=0.002）、上方（<0.001）和颞侧（=0.001）象限中，RPR与SE之间存在负相关。
在不散瞳的情况下，近视眼中的RPR 15-30、30-45、RPR-S和RPR-T值与正视眼之间存在显著差异，且这些差异与SE呈负相关。
