dc.description.abstract | Purpose: To develop and validate a web-based reading test for normal and low vision patients. Methods: This is a prospective, comparative trial. The web-based Democritus Digital Acuity Reading Test (wDDART) was developed. wDDART introduces a series of advanced characteristics (advanced text calibration, computer-vision-based estimation of patient’s distance, and automatic calculation of patient’s reading times) that facilitate the overall examination procedure. wDDART’s reading parameters [reading acuity (RA), maximum reading speed (MRS), critical print size (CPS) and reading accessibility index (ACC)] were compared to the corresponding ones of its conventional Windows-based reading test (DDART) in a sample of normal and low vision participants. wDDART’s test–retest reliability for all reading parameters was evaluated in a 15-day time-window. Results: One hundred patients (normal vision group-NVG: 70; low vision group-LVG: 30 patients) responded to DDART and wDDART. Non-significant differences between the two reading tests were found for all parameters in NVG and LVG. Intraclass correlation coeffi-cients (ICCs) between the two tests demonstrated good or excellent correlation for RA, MRS, ACC and moderate correlation for CPS. Test–retest reliability was excellent for RA and ACC, while ICCs were 0.715–0.895 for MRS and CPS. Conclusion: The wDDART demonstrated sufficient validity and repeatability making it suitable for clinical and research settings.
