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-CRCI application is specifically designed for use in research-ethics-board (REB)-approved clinical studies where only approved study personnel and participants who have signed an REB-approved consent form will be able to use the application via a unique identifier code. The application is designed to record eye movements in patients with Cancer-Related Cognitive Impairment (CRCI) during visual tests presented on the iPad. To do so, the application makes use of Innodem Neurosciences patented eye-tracking technology using the iPads camera. The data collected by this application are being used to validate the application and its underlying algorithms within the context of REB-approved clinical studies. No data is currently being used to provide medical guidance to patients and/or medical professionals, and the application itself will not provide the user with any clinical or medical information following the completion of the visual tests.
