Konan's RAPDx® product has enhanced the ability to view neuro-pupillary dysfunctions. In the 19th century pupil defect testing began but was difficult to perform and inconclusive until now. The notation "PERRLA-MG" regularly appears on patient records as a required part of standard eye exams, even if testing was performed and this can be inaccurate. The RAPDX® is a patented pupillograph that offers standardized, objective technology. It features infrared, HD, and machine-vision and can perform eye-tracking. The device automatically detects blinks and has stimulus rescheduling. The high-fidelity, digital technology is simulataneous and records both consensual and direct responses.
