Both eyes of 74 healthy 2-12-month-old human infants were refracted twice with the new Welch Allyn SureSight non-cycloplegic autorefractor. At least one reliable estimate of sphere and cylinder was obtained from both eyes of all babies attempted, and 88% of infants contributed two estimates from each eye. These measurements were collected in less than 2 min. Although spherical estimates changed little over the first year (mean = +1.78 D), cylindrical error appeared to decrease from a mean of about 1.4 D (at 6 months) to 0.9 D (at 12 months). Refractive estimates and variability agreed well with published infant data obtained with traditional cycloplegic retinoscopy. Repeatability was excellent for measurement of cylinder but for sphere, 17% of infants' estimates differed by at least 1.0 D between tests. However, given its simplicity and time-efficiency, the SureSight should be a good candidate for the relatively easy screening of significant refractive error in non-verbal paediatric patients.
使用新型Welch Allyn SureSight非散瞳自动验光仪对74名2至12个月大的健康人类婴儿的双眼进行了两次验光。在所有接受测试的婴儿中,双眼均至少获得了一次可靠的球镜和柱镜度数估计值,88%的婴儿每只眼睛提供了两个估计值。这些测量在不到2分钟内完成。尽管球镜估计值在第一年变化不大(平均值 = +1.78 D),但柱镜误差似乎从平均约1.4 D(6个月时)降至0.9 D(12个月时)。屈光估计值和变异性与通过传统散瞳视网膜检影法获得的已发表婴儿数据吻合良好。柱镜测量的重复性极佳,但对于球镜,17%的婴儿两次测试的估计值相差至少1.0 D。然而,鉴于其简单性和高效性,SureSight应该是对不会说话的儿科患者进行相对容易的显著屈光不正筛查的良好选择。
