摘要 目的研究Welchallyn Suresight一代(SS1)和二代(SS2)对屈光不正进行测量的可重复性与一致性,评价SS1和SS2的临床应用价值。方法临床病例系列研究。对2013年10月至2014年3月在广州市妇女儿童医疗中心就诊的51例2~16岁(平均年龄10.26岁)屈光不正患者,排除其他眼疾。先在自然瞳孔状态下用SS1和SS2视力筛查仪,Topcon电脑验光仪进行检查,后用0.5%托吡卡胺滴眼液散瞳30—45 min,进行视网膜检影验光,记录屈光状态。可重复性研究采用个体分别测量,三次结果的组内相关系数(intraclass correlation coefficient,ICC)以及重复系数作为重复测量精确性的分析指标。SS1、SS2和Topcon电脑验光仪三组数据,和视网膜检影比较的95%一致性界限,作为一致性的指标。结果(1)在球镜(-5D至+5D)和柱镜度数测量方面,SS1、SS2和Topcon电脑验光仪三组与散瞳后检影结果的差值比较差异无统计学意义(P〉0.05),在球镜(-10D至+5D)和柱镜轴向测量方面,SS1、SS2和Topcon电脑验光仪三组与散瞳后检影结果的差值有统计学意义(P〈0.05)。(2)可重复性:SS1、SS2及Topcon电脑验光仪三者在球镜方面ICC均〉0.75,有很好的可重复性;柱镜度方面SS1的ICC为0.66,SS2和Topcon电脑验光仪ICC分别为0.88和0.99,SS2可重复性较SS1好;柱镜轴向方面SS1和SS2ICC分别为0.73和0.74,在除去柱镜度数小于0.5D的数据后SS1和SS2的测量可重复性有提高,分别为0.85和0.73。(3)95%一致性界限:SS1与视网膜检影法比较的95%一致性界限球镜(-5D至+5D)方面为(-3.09,1.94)D,柱镜方面为(-1.76,1.75)D,柱镜轴向(组内全部数据)方面为(-41.66,53.02)°,柱镜轴向(柱镜度数≥0.5D)方面为(-33.55,32.31)°;SS2与视网膜检影法比较的95%一致性界限球镜(-5D至+5D)方面� Objective To evaluate the repeatability and agreement of Welch Allyn Suresight 1 (ss1), Suresight 2 (ss2) autorefractor in measurements of refractive error as compared to the Topcon autorefractor and retinoscopy. Methods Data from 51 (2- to 16-year-old) cases with no ocular ab- normalities were reported. First, the refractive error was determined in each eye by the Welch Allyn SureSight 1, Suresight 2 autorefractor and Topcon autorefractor with noncycloplegia. Second, streak retinoscopy, measurements were performed approximately 30-45 min after cycloplegia induced by 0.5% tropicamide ophthalmic solutions. The intraclass correlation coefficient (ICC) and the 95% lim- its of agreement for statistical analysis were used. Results There were no statistically significant dif- ference (P 〉0.05) in measurements of sphere (range: -5D to +5D) and cylinder among SS1, SS2 and Topcon autorefractor. There were statistically significant differences (P 〈0.05) in measurements of sphere (range: -10D to +5D) and cylinder axis among SS1, SS2 and Topcon autorefractor. Repeat- ability: The intraclass correlation coefficient (ICC) were 0.97 sphere (range: -5D to +5D), 0.66 cylin- der, 0.73 cylinder axis (full) and 0.85 cylinder axis (abs (cyl) ≥ 0.5) for the SS1 and 0.95 sphere (range: -5D to +5D), 0.97 sphere (range: -10D to +5D), 0.88 cylinder, 0.74 cylinder axis (full) and 0.73 cylinder axis (abs (cyl) ≥ 0.5) for the SS2 and 0.99 sphere (range: -5D to +5D), 0.99 sphere (range:-10D to +5D), 0.89 cylinder, 0.83 cylinder axis (full) and 0.92 cylinder axis (abs (cyl) ≥ 0.5) for the Topcon autorefractor. The ICC of the three devices showed high repeatability. 3. 95% limits of agreement: The 95% limits of agreement were (-3.09, 1.94) diopter (D) sphere (range:-5D to +5D), (-1.76,1.75)D cylinder, (-41.66,53.02) degree cylinder axis (full) and (-33.55,32.31) degree cylinder axi
