To assess the feasibility and performance of Vivid Vision Perimetry (VVP), a new virtual reality (VR)-based visual field platform.
Children 7-18 years of age with visual acuity of 20/80 or better undergoing Humphrey visual field (HVF) testing were recruited to perform VVP, a VR-based test that uses suprathreshold stimuli to test 54 field locations and calculates a fraction seen score. Pearson correlation coefficients were calculated to evaluate correlation between HVF mean sensitivity and VVP mean fraction seen scores. Participants were surveyed regarding their experience.
A total of 37 eyes of 23 participants (average age, 12.9 ± 3.1 years; 48% female) were included. All participants successfully completed VVP testing. Diagnoses included glaucoma (12), glaucoma suspect (7), steroid-induced ocular hypertension (3), and craniopharyngioma (1). Sixteen participants had prior HVF experience, and none had prior VVP experience, although 7 had previously used VR. Of the 23 HVF tests performed, 9 (39%) were unreliable due to fixation losses, false positives, or false negatives. Similarly, 35% of VVP tests were unreliable (as defined by accuracy of blind spot detection). Excluding unreliable HVF tests, the correlation between HVF average mean sensitivity and VVP mean fraction seen score was 0.48 (P = 0.02; 95% CI, 0.09-0.74). When asked about preference for the VVP or HVF examination, all participants favored the VVP, and 70% were "very satisfied" with VVP.
In our cohort of 23 pediatric subjects, VVP proved to be a clinically feasible VR-based visual field testing, which was uniformly preferred over HVF.
评估 Vivid Vision Perimetry（VVP），一种新的基于虚拟现实（VR）的视野平台的可行性和性能。
招募视力为 20/80 或更好的 7-18 岁儿童进行 Humphrey 视野（HVF）测试，以进行 VVP 测试，这是一种基于 VR 的测试，使用超阈值刺激来测试 54 个视野位置，并计算分数。计算 Pearson 相关系数以评估 HVF 平均敏感性与 VVP 平均分数之间的相关性。调查参与者的体验。
共有 23 名参与者的 37 只眼（平均年龄 12.9 ± 3.1 岁；48%为女性）被纳入研究。所有参与者均成功完成 VVP 测试。诊断包括青光眼（12 例）、青光眼疑似（7 例）、类固醇诱导性眼高压（3 例）和颅咽管瘤（1 例）。16 名参与者有之前的 HVF 经验，没有 VVP 经验，尽管有 7 名参与者之前曾使用过 VR。在进行的 23 次 HVF 测试中，由于固视丢失、假阳性或假阴性，有 9 次（39%）不可靠。同样，35%的 VVP 测试不可靠（定义为盲点检测的准确性）。排除不可靠的 HVF 测试后，HVF 平均平均敏感性与 VVP 平均分数之间的相关性为 0.48（P=0.02；95%CI，0.09-0.74）。当被问及对 VVP 或 HVF 检查的偏好时，所有参与者都更喜欢 VVP，70%的人对 VVP“非常满意”。
在我们的 23 名儿科患者队列中，VVP 被证明是一种可行的基于 VR 的视野测试，与 HVF 相比，它普遍受到青睐。
