Purpose: The Olleyes VisuALL-K is a pediatric videogame-based static threshold perimeter using a virtual reality headset. We determined normal threshold sensitivities for the 24-2 test locations using the virtual reality perimetry (VRP) and also tested patients on the Humphrey Field Analyzer (HFA). Patient satisfaction for the two instruments was compared.
Methods: This exploratory study tested 50 normal pediatric participants aged 8 to 17 years on the HFA and VRP. The main outcome measure was threshold sensitivity at the 24-2 test locations for the two instruments.
Results: The mean participant age was 13.0 ± 2.6 years; 50% were female. The threshold values for VRP are reported as measured on the device and after conversion to an HFA-equivalent scale. Age-adjusted thresholds showed a mean sensitivity of 31.8 ± 1.1 dB (46.1 ± dB HFA equivalent) diminution from the maximum light intensity in the VRP and 31.0 ± 1.5 dB diminution from the maximum light intensity in the HFA; interparticipant variability in mean threshold sensitivity was 2.7 ± 0.4 dB for the VRP and 2.7 ± 0.6 dB for the HFA. The HFA demonstrated decreased threshold sensitivity with increasing eccentricity, whereas the VRP threshold did not seem to vary with eccentricity. Mild age effects on threshold sensitivity were seen in the VRP and the HFA (R2 = 0.11, P < 0.001 and R2 = 0.05, P < 0.05, respectively). The mean time to completion for VRP and HFA was 7.6 ± 1.5 and 5.3 ± 0.9 min/eye, respectively (P < 0.0001). Patient satisfaction scores favored VRP (P < 0.01) despite the longer test duration.
Conclusions: The Olleyes game-based VRP and HFA can be used to map out the peripheral vision in normal children. The VRP has a higher patient satisfaction when used in children than the HFA. The portability of the test allows it to be performed in a myriad of environments, lending a flexibility that can benefit this population.
Translational Relevance: This virtual reality perimetry device provides an alternative to the Humphrey Field Analyzer for children.

The study aimed to determine if virtual reality (VR) games could enhance neuromuscular control and improve anticipatory and compensatory strategies in ball-kicking for soccer players. It was a single-blind randomized clinical trial involving 32 male soccer players with chronic ankle instability. Participants were divided into two groups: VR games and balance training.

Recent work has shown rapid microstructural brain changes in response to learning new tasks. These cognitive tasks tend to draw on multiple brain regions connected by white matter (WM) tracts. Therefore, behavioural performance change is likely to be the result of microstructural, functional activation, and connectivity changes in extended neural networks.

Background: This study aims to investigate the effect of a newly developed virtual reality task-oriented training (VR-TOT) video game on upper extremity fine motor function compared with conventional occupational therapy through leap motion in children with spastic hemiplegic cerebral palsy (CP).
Methods: In this double-blind randomized clinical trial, 30 children with spastic hemiplegic CP aged six to 10 years were included and randomly allocated into two groups. During six weeks, 15 patients in the intervention group received VR_TOT-based video game in addition to conventional occupational therapy, whereas 15 patients in the control group received only conventional occupational therapy.

Background: Simulation-based learning (SBL) and augmented reality (AR) /virtual reality (VR) are increasingly adapted and investigated globally to aid traditional teaching methods of clinical skills in several fields of clinical dentistry. This cross-sectional study was, therefore, aimed to assess the availability of such technology to Prosthodontics postgraduate trainees in Pakistan, as well as their introspective views regarding the effectiveness of adapting to simulation-based learning methods.
Method: Total population sampling yielded a sample of 200 participants.
