PURPOSE To introduce a rapid and objective electrophysiological technique that can assess visual function in the magnocellular pathway, which is thought to be affected in early-stage glaucoma. METHODS Low-contrast bright or dark isolated-checks were luminance-modulated against a static background at 10 Hz in order to drive preferentially the magnocellular(More)
The Neucodia system is substantially equivalent to Roland Consult's RETI-Port-Scan (K023525) and LACE Elettronica's GLAID Ocular Electrophysiology Device (K043367). The Neucodia device features are substantially equivalent to the predicate devices with respect to the device's general design concept, operational procedure, data processing methodology, data(More)
