Abstract

Purpose: The accuracy of mobile-based visual acuity testing in clinical practice is debatable. This study aimed to analyze the accuracy of mobile-based distant vision chart in comparison to the standard chart projector.

Methods: In this cross-sectional study, monocular distant best-corrected visual acuity (BCVA) in 571 eyes of 288 subjects was measured twice, using the Tumbling E vision chart by standard chart projector and repeated using mobile-based vision chart application with screen mirroring on a 22-inch monitor. The decimal results of BCVA were compared to analyze the accuracy of the mobile-based chart in comparison to the standard vision chart projector.

Results: The mean age of the studied patients was 29 ± 14 years. The most frequent refractive error was hyperopia (35.4%), followed by emmetropia (26.7%), myopia (22.9%), and astigmatism (14.9%). The mean BCVA in decimal form was 0.9 ± 0.2 and 0.91 ± 0.26 by the standard and mobile-based charts, respectively. An excellent agreement was reported between both tests as the intraclass correlation coefficient (ICC) was 0.976, with a confidence interval (CI) of 0.965-0.982. Bland-Altman analysis revealed that most visual acuity differences between both methods lie on the equality line or within the allowed difference zone.

Conclusions: The mobile-based vision chart is an economical, accessible, and accurate way for distant vision assessment, and its results are comparable to the standard chart projector in clinical practice.

在 COVID-19 大流行期间，基于移动设备的视力表在临床实践中的准确性。

目的：在临床实践中，基于移动设备的视力测试的准确性值得商榷。本研究旨在分析移动式远视力表与标准投影仪相比的准确性：在这项横断面研究中，对288名受试者的571只眼睛的单眼远距离最佳矫正视力（BCVA）进行了两次测量，分别使用标准图表投影仪测量Tumbling E视力表，以及在22英寸显示器上使用带屏幕镜像功能的移动视力表应用程序重复测量。对 BCVA 的十进制结果进行比较，以分析移动式视力表与标准视力表投影仪的准确性：研究对象的平均年龄为 29 ± 14 岁。最常见的屈光不正是远视（35.4%），其次是近视（26.7%）、近视（22.9%）和散光（14.9%）。标准视力表和移动视力表的十进制 BCVA 平均值分别为 0.9 ± 0.2 和 0.91 ± 0.26。两种测试结果的类内相关系数（ICC）均为 0.976，置信区间（CI）为 0.965-0.982，两者之间的一致性极佳。Bland-Altman分析表明，两种方法之间的视力差异大多位于相等线或允许的差异范围内：基于手机的视力表是一种经济、方便、准确的远视力评估方法，其结果与临床实践中的标准视力表投影仪相当。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
