視線追跡機能搭載型 VR ヘッドセットによる眼球運動検査装置の開発

Recording eye movement at a patient’s first visit to primary care is critical, because abnormal eye movement findings can disappear, accompanied by a lessening of symptoms. In addition, sharing such data with an expert institution can support a precise diagnosis. However, recording devices such as ENG and VOG are relatively expensive to introduce to private clinics. In addition, the series of eye movement examinations can take a relatively long time, potentially delaying other medical care. Recent advances in virtual reality (VR) technology have led to the development of VR goggles, which can project 3 D images and also record eye movements. This kind of device can be a useful tool for the development of a novel and affordable instrument for private clinics. We have been participating in the development of a VR goggle-based VOG. This device can record ordinary sequential examinations automatically, to save time. At the same time, we are also developing an advanced model for specialists. In this manuscript, we introduce our novel VOG equipment. In addition, we discuss the possibility of future applications.
