Year: 1984
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
