HINTS Exam vs Eye Tracking Test

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.

The application records slow-motion video of eye movements while a user follows a visual target displayed on the iPhone screen. After recording, users can select a corneal reflection of the screen and a facial reference point to visualize eye movement changes as graphs. The recorded data can be used to review horizontal and vertical eye position and velocity changes for research and educational purposes.
