To evaluate a newly developed, web-based system for at-home pediatric visual acuity testing and to compare results with standard in-office visual acuity test results.
Children aged 3-12 years with and without visual deficits were enrolled (N = 65; 130 eyes). Monocular visual acuity was tested in-office using the ATS-HOTV (ages 3-6) or E-ETDRS (ages 7-12) protocol. Each child's family was emailed a link to a web-based version of the same visual acuity test for at-home testing. Equivalence was evaluated by using a linear mixed model to estimate the mean difference between in-office and at-home visual acuity test results and the corresponding two-sided 95% confidence interval.
For children tested with the ATS-HOTV protocol, the mean difference between in-office and at-home visual acuity test results was 0.01 log MAR (95% CI, -0.06 to 0.09). For children tested with the E-ETDRS protocol, the mean difference was 0.04 log MAR (95% CI, -0.06 to 0.14).
At-home, web-based ATS-HOTV and E-ETDRS visual acuity test results had excellent concordance with in-office visual acuity testing. If the burden of travel is significant, at-home testing of children's visual acuity may provide the information needed to continue care when it might otherwise be discontinued or delayed.
评估一种新开发的、基于网络的家庭儿科视力测试系统，并将其结果与标准的门诊视力测试结果进行比较。
招募了有或没有视力缺陷的 3-12 岁儿童（N=65；130 只眼）。使用 ATS-HOTV（3-6 岁）或 E-ETDRS（7-12 岁）方案在门诊进行单眼视力测试。每个孩子的家庭都会收到一封电子邮件，其中包含一个链接，可以访问相同的视力测试的网络版，用于家庭测试。通过使用线性混合模型来估计门诊和家庭视力测试结果之间的平均差异及其相应的双侧 95%置信区间，来评估等效性。
对于使用 ATS-HOTV 方案进行测试的儿童，门诊和家庭视力测试结果之间的平均差异为 0.01 logMAR（95%CI，-0.06 至 0.09）。对于使用 E-ETDRS 方案进行测试的儿童，平均差异为 0.04 logMAR（95%CI，-0.06 至 0.14）。
家庭网络版 ATS-HOTV 和 E-ETDRS 视力测试结果与门诊视力测试具有极好的一致性。如果旅行的负担很大，那么家庭测试儿童的视力可能会提供必要的信息，以继续进行治疗，否则可能会中断或延迟。
