FushikiVOG vs HINTS Exam

This is a VOG (video-oculography) app that works on an iPhone. It records eye movements and analyzes the recorded video to display the eye movements as graphs. Visual targets for tests such as smooth pursuit and saccadic eye movements are displayed on the screen. At the same time, the iPhone camera records the eye movements as the user follows the target. The recorded video is then analyzed and displayed as graphs, allowing smooth pursuit and saccade tests to be performed easily.

This app was developed to enhance the HINTS exam by using a smartphone to better facilitate effective exam implementation and improve posterior CVA detection for enhanced patient outcomes within primary care, urgent care, and emergency care settings. This application allows for a streamlined screening process, with most full exams being concluded within five minutes from the start, and subjectively, being able to replay the exam video at half-speed allowed for a much easier and more confident assessment of nystagmus direction, skew deviation, and head impulse test corrective saccade with correct training and understanding of the exam's application. The smartphone application starts by taking the user through several screening questions to help determine if the application is appropriate or if a stroke workup is highly indicated. Videos are recorded for review and can be slowed down for optimal evaluation.
