Summary

• 78 subjects
• VEP and Psyc thresholds can be quite uncorrelated with glaucoma, the two types of thresholds contain independent information about glaucoma that could be usefully combined

Learnings

• psychophysical studies of contrast thresholds revealed that testing at temporal frequencies (TF) of 8–10 Hz and spatial frequencies (SF) B1 cpd had good sensitivity for glaucoma
• low SF stimuli modulated at somewhat higher TF, such that they displayed the frequency doubling (FD) illusion, were reported to provide improved ability to diagnose glaucoma
• low spatial frequencies (<0.25 cpd) and high temporal frequencies (20–23 Hz) have been reported to be somewhat non-monotonic
