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.

目的

Olleyes VisuALL-K 是一种基于儿童电子游戏的静态阈值周边视野检查仪，采用虚拟现实头盔。我们使用虚拟现实周边视野检查仪（VRP）确定了 24-2 个测试点的正常阈值敏感度，并在 Humphrey 视野分析仪（HFA）上对患者进行了测试。比较了两种仪器的患者满意度。

方法

本探索性研究对 50 名 8 至 17 岁的正常儿科参与者在 HFA 和 VRP 上进行了测试。主要观察指标为两种仪器 24-2 个测试点的阈值敏感度。

结果

参与者的平均年龄为 13.0 ± 2.6 岁；50%为女性。VRP 的阈值值报告为设备上的测量值，以及转换为 HFA 等效标度后的测量值。年龄调整后的阈值显示，VRP 中的最大光强度降低了 31.8 ± 1.1 dB（46.1 ± dB HFA 等效），HFA 中的最大光强度降低了 31.0 ± 1.5 dB；VRP 的平均阈值敏感度的组间变异性为 2.7 ± 0.4 dB，HFA 的平均阈值敏感度的组间变异性为 2.7 ± 0.6 dB。HFA 显示阈值敏感度随离中心距离的增加而降低，而 VRP 阈值似乎不受离中心距离的影响。VRP 和 HFA 中均观察到轻度的年龄对阈值敏感度的影响（R2 = 0.11，P < 0.001 和 R2 = 0.05，P < 0.05）。VRP 和 HFA 的平均完成时间分别为 7.6 ± 1.5 和 5.3 ± 0.9 min/眼（P < 0.0001）。尽管测试时间较长，但患者对 VRP 的满意度更高（P < 0.01）。
