Background

Our previous validation studies indicated that automated best corrected visual acuity (BCVA) testing using the DigiVis web application is comparable to standard testing.

Methods

Electronic records of children assigned follow up remote consultation with home DVA testing for their routine clinical care between March 2021 and October 2024 were reviewed.

n = 142 families

Results

91.2%

eye-vision testing at home gave usable results for most patients

n = 142 families

More results

205 remote consultation appointments with DVA testing were scheduled for children (aged 4-14, median 6 years).

DVA results were available for 192 (93.7%) RCs, with 166 (86.5%) tests undertaken without clinical supervision.

More results

The mean bias between serial BCVA and DVA was 0.005 logMAR (p < 0.001) with upper and lower limits of agreement of +0.182 (95%CI: 0.169 to 0.195) and -0.173 (-0.186 to -0.160) logMAR respectively.

116 (81.7%) of 142 families voluntarily completing Likert scoring rated the application good/excellent.

Conclusion

In this real-world evaluation, 91.2% of offered DVA tests were informative and contributed to clinical decision making. DVA correctly identified unexpected deterioration in 9 children supporting the utility of this innovative service model.
