“…It showed its reliability with a correct agreement with the Rossano-Weiss test (ICC 0.43), 95% correspondence for the best visual acuity and a mean difference in visual acuity of 0.06 logMAR between the two tests. These results are good compared to those of studies that have developed similar tests (12,13). The eMOVA test is reproducible (ICC 0.93) and simple.…”

Background Amblyopia is a major public health problem. Its screening and management require reliable methods of assessing visual acuity. Many tests are available, some of which are used as a reference and the advent of new technologies sees many others whose validity is not proven. The objective of our study was to develop a tablet-based visual acuity test adapted to the pediatric population: the eMOVA test (electronic Measurement Of Visual Acuity). Methods We did a study comparing the eMOVA test with the Rossano-Weiss test. All children aged 3 to 8 attending the ophthalmic and pediatric consultation between September 2016 and June 2017 were included. The results in terms of visual acuity were compared as well as the duration of each test, its comprehension, its acceptability and the attention of the child during the test. Results The eMOVA test overestimated visual acuity by 0.06 logMAR. This difference, statistically significant, was not clinically relevant. The duration of the eMOVA test was longer than the reference test, but it was less painful and more appreciated by children and their parents. Conclusion The e-MOVA test appears as a reliable method of assessing visual acuity that could be used both in consultation and on a larger scale in the context of screening as well as for the care of the most difficult children.

“…This last point is crucial, as tests must be must be simple, intuitive, and engaging if to be completed autonomously by patients, without the need for costly technicians. 41 There was no relationship between performance on the tablet tests, and scores on a test of cognitive function (Digit Span). This is encouraging, as it suggests that they are measuring genuine perceptual abilities, rather than general cognitive ability or effort.…”

“…They also defined cutoff points for what constitutes ‘normal’ performance, and showed that the tests could be performed easily by young adults, who, anecdotally, often regarded them as ‘games’ (in contrast to the vision screening ‘tests’ that preceded them).

“…The present work is timely, as a number of other tabletbased tests have recently been reported, designed to measure various more basic aspects of visual function, such as visual acuity, 15,41,43,44 contrast sensitivity, [45][46][47][48][49] visual fields, 12,50-56 stereopsis, 57 and colour vision. 58,59 What distinguishes the tests described in the present study is that they are intended to measure 'high-level' function on everyday tasks.…”

Purpose To describe, refine, evaluate, and provide normative control data for two freely available tablet‐based tests of real‐world visual function, using a cohort of young, normally‐sighted adults. Methods Fifty young (18–40 years), normally‐sighted adults completed tablet‐based assessments of (1) face discrimination and (2) visual search. Each test was performed twice, to assess test‐retest repeatability. Post‐hoc analyses were performed to determine the number of trials required to obtain stable estimates of performance. Distributions were fitted to the normative data to determine the 99% population‐boundary for normally sighted observers. Participants were also asked to rate their comprehension of each test. Results Both tests provided stable estimates in around 20 trials (~1–4 min), with only a further reduction of 14%–17% in the 95% Coefficient of Repeatability (CoR95) when an additional 40 trials were included. When using only ~20 trials: median durations for the first run of each test were 191 s (Faces) and 51 s (Search); test‐retest CoR95 were 0.27 d (Faces) and 0.84 s (Search); and normative 99% population‐limits were 3.50 d (Faces) and 3.1 s (Search). No participants exhibited any difficulties completing either test (100% completion rate), and ratings of task‐understanding were high (Faces: 9.6 out of 10; Search: 9.7 out of 10). Conclusions This preliminary assessment indicated that both tablet‐based tests are able to provide simple, quick, and easy‐to‐administer measures of real‐world visual function in normally‐sighted young adults. Further work is required to assess their accuracy and utility in older people and individuals with visual impairment. Potential applications are discussed, including their use in clinic waiting rooms, and as an objective complement to Patient Reported Outcome Measures (PROMs).

Development and testing of an automated computer tablet-based method for self-testing of high and low contrast near visual acuity in ophthalmic patients

Abstract: This study demonstrates the potential utility of the MAVERIC system for patients with ophthalmic disease to self-test their high and low contrast VA. The technique has a high degree of reliability and agreement with gold standard chart based measurements.
