RPRs were measured using MRT without mydriasis. MRT results showed RPR at 0-15\u00b0 (RPR 0-15), 15\u00b0-30\u00b0 (RPR 15-30), and 30\u00b0-45\u00b0 (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.\nRESULTS: 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)] (P&lt;0.05), MM and E [-0.06 (-0.20; 0.10)] (P&lt;0.05), and LM [-0.02 (-0.15; 0.15)] and E (P&lt;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)] (P&lt;0.05), and LM [0.44 (0.14; 0.76)] and E (P&lt;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)] (P&lt;0.001), and LM [-0.28 (-0.71; 0.12)] and E (P&lt;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)] (P&lt;0.05), LM [0.41 (0.06; 0.84)] and LH (P&lt;0.05), and LM and E [0.29 (-0.10; 0.68), P&lt;0.05]. A Spearman\u2019s correlation analysis showed a negative correlation between RPR and SE in the 15\u00b0-30\u00b0 (P=0.005), 30\u00b0-45\u00b0 (P&lt;0.05) annular (P=0.002), superior (P&lt;0.001), and temporal (P=0.001) quadrants.\nCONCLUSION: 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.<\/jats:p>","DOI":"10.18240\/ijo.2024.08.13","type":"journal-article","created":{"date-parts":[[2024,7,24]],"date-time":"2024-07-24T06:19:12Z","timestamp":1721801952000},"page":"1477-1482","source":"Crossref","is-referenced-by-count":7,"title":["Relative peripheral refraction in school children with different refractive errors using a novel multispectral refraction topographer"],"prefix":"10.18240","volume":"17","author":[{"name":"Shenzhen Eye Hospital, Jinan University, Shenzhen Eye Institute, Shenzhen 518040, Guangdong Province, China","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hui-Ling","family":"Hu","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ai-Ying","family":"Feng","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"name":"Shenzhen Eye Hospital, Jinan University, Shenzhen Eye Institute, Shenzhen 518040, Guangdong Province, China","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hao-Xi","family":"Zhong","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"name":"Shenzhen Eye Hospital, Jinan University, Shenzhen Eye Institute, Shenzhen 518040, Guangdong Province, China","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jing-Feng","family":"Mu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"name":"Shenzhen Eye Hospital, Jinan University, Shenzhen Eye Institute, Shenzhen 518040, Guangdong Province, China","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mei-Zhou","family":"Liu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"name":"Shenzhen Eye Hospital, Jinan University, Shenzhen Eye Institute, Shenzhen 518040, Guangdong Province, China","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"7543","container-title":["International Journal of Ophthalmology"],"original-title":[],"link":[{"URL":"http:\/\/ies.ijo.cn\/en_publish\/2024\/8\/20240813.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2024,7,24]],"date-time":"2024-07-24T06:19:32Z","timestamp":1721801972000},"score":1,"resource":{"primary":{"URL":"http:\/\/ies.ijo.cn\/gjyken\/ch\/reader\/view_abstract.aspx?file_no=20240813&flag=1"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2024,8,18]]},"references-count":0,"journal-issue":{"issue":"8","published-print":{"date-parts":[[2024,8,18]]}},"URL":"https:\/\/doi.org\/10.18240\/ijo.2024.08.13","relation":{},"ISSN":["2222-3959","2227-4898"],"issn-type":[{"value":"2222-3959","type":"print"},{"value":"2227-4898","type":"electronic"}],"subject":[],"published":{"date-parts":[[2024,8,18]]}}}
