AdaptDx Pro® Dark Adaptometer
The AdaptDx Pro, now made by OpZira (formerly MacuLogix and LumiThera), is a self-contained, head-mounted dark adaptometer that measures Rod Intercept (RI) time, a functional biomarker of age-related macular degeneration. Its onboard AI technician, Theia, guides the patient through the test with spoken instructions, so no dark room, external computer or dedicated technician is required, making it practical for multi-site clinical trial endpoints.
