Eye tracker-based differentiation of causes of acute Vertigo: A mobile approach for faster and more accurate triage and diagnosis

Background Acute vertigo poses a significant detriment to the quality of life, stemming from a variety of causes that span from peripheral vestibular disorders to severe conditions like stroke. Swiftly identifying the root cause of vertigo is imperative for providing timely and appropriate treatment. Material and Methods Our study aimed to develop an innovative method facilitating the differentiation of vertigo causes through straightforward technical tools. We devised a protocol utilizing an eye-tracker and artificial intelligence, with the goal of accurately pinpointing the origin of vertigo, akin to the clinical neurological and ENT standard examination (HINTS exam). Using Microsoft HoloLens, voice-guided instructions dynamically instruct patients to perform specific eye movements while maintaining a steady head position. During other phases of the examination, patients are directed to move their heads while keeping their gaze fixed. While the analysis is currently executed using the HoloLens, there is future potential for application through a smartphone app. Results The HoloLens enables the identification of eye movement patterns, such as nystagmus and skew deviation. Through our meticulously designed test setup, patients experiencing vertigo can be distinguished from healthy individuals, and differentiation between central and peripheral vertigo is achievable. The development of the eye-tracker was a collaborative effort involving engineers, neurologists, and ENT specialists. Conclusion The eye-tracker exhibits promising potential for advancing the care of vertigo patients. By broadening access to a dependable and rapid analysis of vertigo causes, more individuals at risk of a stroke could be identified and treated within the critical lytic window.
