Abstract

BACKGROUND/AIM: Acuity charts that follow the principle of logarithmic size progression (logMAR charts) are considered to be the gold standard for the assessment of distant vision. But it is not well accepted for routine eye examinations due to increased testing time and the complexity of scoring. This study was designed to check whether a modified logMAR chart with three optotypes would provide a reliable acuity assessment compared to standard logMAR charts for routine eye examination.

MATERIALS AND METHODS

Two versions of modified and standard logMAR charts were designed, constructed, and used to assess the visual acuity of 50 individuals drawn from a typical out-patient population. Timed test-retest variability and limit of agreement (95% confidence limit of agreement) of the modified chart are compared to the standard logMAR chart using Bland-Altman method. A comparison of the testing time was carried out using paired t-test.

RESULTS

The test-retest variability of the charts was comparable, with 95% confidence limit of the mean difference being ±0.08 for standard logMAR and ±0.10 for modified logMAR. Both the versions of modified logMAR charts produced the results which agreed well with those of the standard logMAR charts. The mean testing time required to complete the acuity measurements with the modified chart was significantly lesser compared to the standard chart (P < 0.001).

CONCLUSION

The outcomes of the current study demonstrates that the modified logMAR chart with three optotypes offers a comparable result to the standard logMAR charts for assessing distant visual acuity in routine clinical examination set up with a much lesser testing time.

摘要

背景/目的：遵循对数尺寸递增原则的视力表（对数视力表）被认为是评估远视力的金标准。但由于测试时间增加和评分复杂，它在常规眼科检查中未被广泛接受。本研究旨在检验与标准对数视力表相比，一种包含三种视标类型的改良对数视力表在常规眼科检查中是否能提供可靠的视力评估。

材料与方法

设计、制作了两种版本的改良对数视力表和标准对数视力表，并用于评估从典型门诊人群中抽取的50名个体的视力。使用Bland-Altman方法将改良视力表的定时重测变异性和一致性界限（一致性的95%置信界限）与标准对数视力表进行比较。使用配对t检验对测试时间进行比较。

结果

两种视力表的重测变异性相当，标准对数视力表平均差异的95%置信界限为±0.08，改良对数视力表为±0.10。两种版本的改良对数视力表得出的结果与标准对数视力表的结果高度一致。与标准视力表相比，使用改良视力表完成视力测量所需的平均测试时间显著更短（P < 0.001）。

结论

本研究结果表明，在常规临床检查中，包含三种视标类型的改良对数视力表在评估远视力方面与标准对数视力表结果相当，且测试时间更短。
