• Threshold isopters for five standard test stimuli of the Goldmann perimeter were determined in 148 eyes of 74 patients with varying degrees of cataractous lens changes. Threshold sensitivity was correlated with visual acuity levels to quantitate the extent of isopter depression for these test stimuli. Composite threshold patterns for each stimulus at each of seven different acuity levels were determined.
