A supra-threshold test, used to screen patients with no known disease, measuring 2 levels of sensitivity (27 dB and 25 dB). Values are color coded in comparison with normative intervals. Typical duration (37 stimuli) is 2 min per eye.
A supra-threshold test, used to examine highly pathologic patients, measuring one level of sensitivity (0 dB). Typical duration (37 stimuli) is about 2 min per eye.
4 LEVELS FIXED:
A supra-threshold test, used to examine pathologic patients, measuring 4 levels of sensitivity (0 dB, 5 dB, 15 dB, 25 dB). Typical duration (37 stimuli) is about 3 min per eye.
FULL THRESHOLDl 4-2:
Test used to examine retinal sensitivity in detail. The average threshold (dB) is color coded in comparison with normative intervals. Typical duration (37 stimuli) is less than 6 min per eye.
Measures exactly the same locations with the same projection strategy as in the baseline test, independent of fixation shifts.
