The study demonstrates mobile devices can accurately assess pupillary light reflex, indicating a new approach to neural function evaluation.
The present study provided preliminary evidence demonstrating that nascent technologies now available on mobile devices are capable of providing accurate and easy estimation of the PLR. The development of such technologies offers a cost-effective solution and expands the scope of PLR testing (as a measure of neural function) to a range of environments and situations not limited to laboratory or clinical settings.
