Abstract

PURPOSE

To validate the Democritus Digital Acuity and Reading Test (DDART) as a distance VA (dVA) test against a series of prevalent conventional distance vision charts.

SETTING

Ophthalmology Department, University Hospital of Alexandroupolis, Alexandroupolis, Greece; Ophthalmology Department, AHEPA University Hospital, Thessaloniki, Greece; and Ophthalmica Institute of Ophthalmology & Microsurgery, Thessaloniki, Greece.

DESIGN

Prospective multicenter validation study.

METHODS

The distance best spectacle-corrected visual acuity (dBSCVA) was compared in normal (NVG) and low (LVG) vision participants against 4 prevalent conventional distance vision charts (ETDRS, Snellen, Landolt C, and Tumbling E) by a predefined 2.5-symbol noninferiority margin and intraclass correlation coefficients (ICCs). DDART's test-retest (TRT) reliability was assessed with ICCs.

RESULTS

534 participants (471 and 63 with normal and low vision, respectively) were included in the study. The mean difference between dBSCVA measured with DDART and conventional charts ranged between -0.84 and +0.85 symbols, without exceeding the 2.5-symbol noninferiority margin. ICCs indicated an excellent level of agreement for all patient groups (from 0.848 to 0.985). TRT reliability indicated differences below 1 symbol both for the NVG and LVG, with ICCs ranging between 0.912 and 0.964 for the 4 DDARTs.

CONCLUSIONS

DDART was a valid web-based dVA test that provided reliable measurements in clinical and telemedical settings, both for normal and low vision patients.

摘要

目的

验证德谟克利特数字视力和阅读测试（DDART）作为一种距离 VA（dVA）测试，与一系列流行的传统距离视力表相比的有效性。

地点

希腊亚历山德鲁波利斯大学医院眼科系；希腊塞萨洛尼基 AHEPA 大学医院眼科系；希腊塞萨洛尼基眼科研究所眼科和显微外科。

设计

前瞻性多中心验证研究。

方法

通过预设的 2.5 个符号非劣效性边界和组内相关系数（ICCs），将正常视力（NVG）和低视力（LVG）参与者的最佳矫正距离视力（dBSCVA）与 4 种流行的传统距离视力表（ETDRS、Snellen、Landolt C 和 Tumbling E）进行比较。使用 ICCs 评估 DDART 的测试-重测（TRT）可靠性。

结果

本研究共纳入 534 名参与者（分别为 471 名和 63 名正常视力和低视力者）。DDART 测量的 dBSCVA 与常规图表之间的平均差异在-0.84 到+0.85 个符号之间，未超过 2.5 个符号的非劣效性边界。所有患者群体的 ICCs 均表明具有极好的一致性（从 0.848 到 0.985）。TRT 可靠性表明，对于 NVG 和 LVG，差异均低于 1 个符号，4 个 DDART 的 ICC 范围在 0.912 到 0.964 之间。
