The purpose of this study was to assess the feasibility of testing binocular visual acuity using the automated acuity card procedure (AACP)-a new automated method that uses an eye-tracking system. We included participants aged 5 to 36 months old. Binocular grating acuity was tested using the AACP and Teller Acuity Cards (TACs) with a uniform testing distance (55 cm) in random order. Electronic stimuli in the AACP were similar in size and form to TACII and roughly equivalent to the printed TACII stimuli. The AACP tracked the participant's gaze from the recorded image sequences and automatically determined the grating acuity. Differentiation, correlation, and consistency were compared between the AACP and TACs. Ultimately, 77.11% (155/201) of participants completed both tests. Fewer participants failed the TAC test than the AACP (15 [7.46%] vs. 31 [15.42%]). The average duration of the AACP (median interquartile range [IQR] = 60 [IQR = 41] seconds) was significantly shorter than that of the TAC (median [IQR], 185 [IQR = 66] seconds, p < 0.001). AACP and TAC visual acuities were robustly correlated (r = 0.83, p < 0.001). Bland-Altman plots revealed a mean difference between AACP and TAC visual acuities of 0.10 cycles per degree (cpd; 95% limits of agreement = 7.70 cpd). Both the AACP and TACs indicated improved visual acuity with age progression (both, p < 0.001), with no significant differences between the tests. Electronic stimuli were presented using the AACP yielded clinically useful data on grating acuity in infants and toddlers. AACP performance was comparable to that of TACs, the current clinical gold standard for assessing infant vision regarding testability, reliability, and accuracy.
本研究旨在评估使用自动视力卡程序（AACP）测试双眼视力的可行性，这是一种使用眼动追踪系统的新自动化方法。我们纳入了 5 至 36 月龄的参与者。使用 AACP 和 Teller 视力卡（TACs）以统一的测试距离（55 厘米）随机顺序测试双眼光栅视力。AACP 中的电子刺激在大小和形式上与 TACII 相似，大致相当于印刷的 TACII 刺激。AACP 从记录的图像序列中跟踪参与者的注视，并自动确定光栅视力。比较了 AACP 和 TACs 的可区分性、相关性和一致性。最终，77.11%（155/201）的参与者完成了两项测试。与 AACP 相比，TAC 测试失败的参与者更少（15 名[7.46%]与 31 名[15.42%]）。AACP 的平均持续时间（中位数[四分位距（IQR）]为 60 [IQR = 41] 秒）明显短于 TAC（中位数[IQR]为 185 [IQR = 66] 秒，p<0.001）。AACP 和 TAC 视力均高度相关（r=0.83，p<0.001）。Bland-Altman 图显示 AACP 和 TAC 视力之间的平均差异为 0.10 个圆周/度（cpd；95%一致性界限=7.70 cpd）。AACP 和 TAC 均表明随着年龄的增长视力得到改善（均 p<0.001），且两种测试之间无显著差异。使用 AACP 呈现的电子刺激可在婴儿和幼儿中获得有关光栅视力的临床有用数据。AACP 的性能与 TACs 相当，后者是评估婴儿视力的当前临床金标准，在可测试性、可靠性和准确性方面均如此。
