Abstract

Purpose : To develop the mobile application runs on VR headsets for low vision aids

Methods : We developed the mobile application on VR device platform for low vision aids that can adjust the illumination, color, and size of the images. Inclusion criteria of this study were those of 20 years of age or older who met one of the following two criteria: 1) who has a visual acuity of less than 6/18 to light perception, or 2) who has a visual field less than 10 degrees from the point of fixation. We excluded patients who could not wear a virtual reality device or whose visual acuity could not be measured. Visual acuity and contrast sensitivity at distance and at near were measured with and without VR device. Visual performance was evaluated with reading speed (words per minute (WPM), letters per minute (LPM)) were also measured and compared.

Results : 10 patients with mean age of 26.0 ± 5.3 years were enrolled. Four patients were diagnosed with congenital optic atrophy and four patients were diagnosed with retinal pigment epithelium. Two patients were diagnosed with proliferative diabetic retinopathy. All patients used the VR device comfortably after 1 hour of training. Visual acuity at far and near showed at least three lines of improvement. Improvement of contrast sensitivity test at far and near distance were also observed at 3, 6, and 12 cyc/deg in each eye with VR device. With the VR device, both reading speed of printed paper and computer display were improved by 1.40 times faster (LPM: 211.00 ± 7.28 to 296.00 ± 9.38, WPM: 71.75 ± 5.40 to 99.50 ± 6.58). Only one case with congenital nystagmus had problem with finding the previous point of reading.

Conclusions : Low vision aids mobile application with VR headsets provided significant improvement in visual quality and performance. This application could be alternative to conventional low vision devices at affordable cost.
