EyeKinetix

Checking pupils for RAPDs is an important part of the comprehensive eye exam and is recommended in the AAO’s Preferred Practice Patterns for POAG suspects and patients. However the swinging flashlight test is difficult for humans to do well, and even more difficult and time consuming to accurately quantify. Importantly, there is evidence that very small RAPD’s may be clinically significant.

EyeKinetix utilises a high-definition, machine-vision system under controlled infrared conditions to present monocular visual stimuli while recording binocular pupil responses. Unlike human observers that only see one eye response at a time, EyeKinetix simultaneously images both direct and consensual light responses. The power of the system is to collect a series of responses and average them into a consolidated response curve. Pupil testing is notoriously non-standardized, variable, and noisy. Response averaging significantly helps filter the noise inherent in the biological responses.
