Virtual reality-based digital defocus vision training may aid myopia in children
Virtual reality-based digital defocus vision training (DDVT) may be a promising adjunctive approach for pediatric myopia control, according to a study published online Aug. 27 in JAMA Ophthalmology.
A recent study published in JAMA Ophthalmology suggests that virtual reality-based digital defocus vision training (DDVT), when combined with single-vision spectacles, may help control myopia progression in children. In this randomized trial, 120 children aged 6 to 12 were divided into two groups: one receiving DDVT for 15 minutes daily along with spectacles, and the other receiving spectacles alone.
After six months, the DDVT group showed a 0.11 mm slower increase in axial length and a 0.23 D slower refractive progression compared to the SVS group. Additionally, visual acuity improved by 0.02 logMAR (Snellen equivalent of 20/18) in the DDVT group, while it improved by 0.01 logMAR (20/20) in the SVS group. These findings indicate that DDVT may offer an adjunctive approach to pediatric myopia control, but the long-term clinical relevance of these results remains uncertain. No adverse events were reported related to the training.
