Summary

• battery of vision tests was used to quantify visual defect
• static contrast sensitivity function appears to be the most sensitive method of measuring visual defect in glaucoma patients
• vertical sinewave gratings

Learnings

• general trend suggests that mechanisms at middle and high spatial frequencies may be more vulnerable in the early stages of the disease
• as the disease progresses the lower spatial frequencies become involved. Such a trend would help to explain why losses at low spatial frequencies (below 2 cpd) are not found consistently
