Oculomotor Reflexes as a Test of Visual Dysfunctions in Cognitively Impaired Observers

Abstract

We successfully developed and implemented a pilot battery of tests designed to diagnose various visual dysfunctions. The principal hardware and software components of data acquisition and analysis pipeline are in place now. The visual stimulation and data collection units were tested on 26 naive observers with normal vision. We used the collected data to design software filters for automatic detection of oculomotor reflexes. These results mostly complete the first phase of the project and allow us to start the next phase, which focuses on two goals: making the developed battery of visual tests adaptive, and testing a large number of normal subjects to establish the distribution of responses for people with normal (reference) visual functions.
