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 coefficients (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.Clinicaltrials.gov Identifier: NCT04618224.Keywords: presbyopia, reading speed, critical print size, reading acuity, computer vision distance estimation, automatic reading timing, internet, readingLabiris GPanagiotopoulou EKDuzha ETzinava MPerente AKonstantinidis ADelibasis KDove Medical Pressarticlepresbyopiareading speedcritical print sizereading acuitycomputer vision distance estimationautomatic reading timinginternetreadingOphthalmologyRE1-994ENClinical Ophthalmology, Vol Volume 15, Pp 3915-3929 (2021)
