目的-这项研究的目的是测试的便携式计算机驱动的，头戴式视野测试系统的能力，在他们的床边对患者进行自动视野检查，并将这些结果与“金标准”的床边检查，对抗visualfields. Methods-的Kasha视野系统是一个便携式自动周边，利用虚拟现实耳机。对37例神经外科病人进行了正视视野检查后，在床边进行了中央24度阈上检查。视野缺损的模式进行了分类，并与对抗testing.Results-A共完成了42场检查37例，平均测试时间为4.8分钟，双眼视野系统的结果进行比较。在对抗测试中被分类为缺陷的11个视野（100%）中的每一个都在头戴式视野检查中被类似地分类。26的31（84%）视野是正常的对抗和视野检查测试，而5的31个领域（16%），这是充分的对抗有视野缺陷的头戴式perimetry.Conclusion-The头戴式，自动视野检查系统被证明很容易便携，方便检查神经外科患者在围手术期的床边。该设备在检测视野缺陷方面表现出与构象视野测试方法相同的灵敏度，并提供了标准化、可量化测试的优势，并提供了用于后续检查的图形结果。
Aim-This study was designed to test the ability of a portable computer driven, head mounted visual field testing system to perform automated perimetry on patients at their bedside and to compare these results with the "gold standard" for bedside examinations, confrontation visual fields.Methods-The Kasha visual field system is a portable automated perimeter which utilises a virtual reality headset. 37 neurosurgery patients were examined at their bedside with a central 24 degree suprathreshold testing strategy after confrontation visual field testing. The patterns of visual field defects were categorised and compared with the results of confrontation testing.Results-A total of 42 field examinations were completed on 37 patients, and the average testing time for both eyes was 4.8 minutes with the perimetry system. Each of the 11 fields (100%) classified with defects on confrontation testing was similarly categorised on head mounted perimetry. 26 out of 31 (84%) visual fields were normal on both confrontation and perimetry testing, while five out of the 31 fields (16%) which were full on confrontation had visual field defects identified by head mounted perimetry.Conclusion-The head mounted, automated perimetry system proved easily portable and convenient for examining neurosurgical patients at their bedside in the perioperative period. The device demonstrated equal sensitivity to conformation visual field testing methods in detecting field defects and offers the advantage of standardised, quantifiable testing with graphic results for follow up examinations.
