Konan Medical objectiveFIELD® Analyser (OFA)
Overview
The objectiveFIELD® Analyzer (OFA®) is the first and only truly objective perimeter FDA 510(k) cleared to assess visual field abnormalities — with no button for the patient to press. Using a novel method called multifocal pupillographic objective perimetry (mfPOP), it tests both eyes simultaneously and concurrently in as little as 90 seconds, making it ideal for patients who cannot reliably respond to conventional perimetry. Cortically mediated pupillary responses are recorded under infrared light, delivering four visual fields per exam — OD & OS sensitivity plus OD & OS delay.
Key Features
Truly objective — no button to press, no cognitive or motor response required from the patient
Bilateral testing — both eyes examined simultaneously, no eye patch needed
Test protocols as fast as 90 seconds for both eyes (30°, 24°, 15° and 10° protocols available)
OFA 30 protocol tests 24° and 30° fields simultaneously at no extra time cost
Measures both sensitivity (dB scale) and delay (ms) — providing information unavailable in any other perimeter
Novel mfPOP stimuli — less susceptible to refractive error, gaze error and lens brunescence from cataracts
Reports in classic format: greyscale and numeric maps, plus global VF indices (MD, PSD, SF, CPSD)
Clinically validated correlation of glaucomatous RNFL loss with visual field findings
