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

Abstract

We successfully developed and implemented a battery of visual tests designed to diagnose various visual dysfunctions by means of recording and objectively analyzing passive oculomotor reflexes. All hardware and software components of the data acquisition and analysis pipeline were finalized and tested in realistic experimental conditions on normal observers and several observers with visual dysfunctions. Observers received no instructions from us regarding their task except for attending to the screen. This passive viewing regime imitated experimental conditions for testing cognitively impaired patients. The project results indicate that the adopted paradigm has sufficient statistical power to successfully diagnose various visual dysfunctions, which validates the proposed approach.
