Abstract

Purpose: To investigate the correlation of the visual function assessed using a smartphone and low-end virtual-reality (VR) device with test results of phoria and fusional vergence.
Methods: Twenty people, including nine men and eleven women, with a normal or corrected visual acuity of over 1.0 and an average age of 23.05 ± 1.05 years, were selected as participants. The ocular deviation and horizontal fusional vergence of the central and peripheral regions were measured using a VR device and compared with the horizontal phoria and fusional vergence results at near and distance, obtained using a phoropter.
Results: The horizontal ocular deviation obtained using the VR device relatively correlated with the phoria at near (p = 0.068, r = 0.416). Further, the total fusional vergence obtained using the VR device showed relatively significant correlations with the total fusional vergence in foveal and peripheral regions of the visual function at near (foveal: p = 0.030, r = ?0.487; peripheral: p = 0.063, r = ?0.424).
Conclusions: Measuring trends in the visual function with the use of smartphones and inexpensive VR devices is possible.
