Eye Tracking Neurological Assessment (ETNA) is a family of science-based applications developed to aid with the evaluation and monitoring of neurological disorders. The ETNA-UPN-HC application is specifically designed for healthy control subjects for comparison with patients who suffer from neurological disorders that are known to affect eye movements. Using its patented eye-tracking technology, Innodem Neurosciences has developed an intuitive AI-powered mobile application to assist clinicians in monitoring disease status and progression in support of traditionally used evaluation tools. These applications make use of non-invasive eye-movement-based tests performed on an iPad and provide precious historical eye-tracking data to the physician who can thereby adapt treatment accordingly for better patient outcomes. Furthermore, patients can self-test in minutes in the comfort of their own homes.
