Measuring Contrast Sensitivity in Specific Areas of Vision - A Meaningful Way to Assess Quality of Life and Ability to Perform Daily Activities in Glaucoma.

: To investigate: 1) the impact of reduced contrast sensitivity (CS) in specific areas of vision on subjective assessment of vision-related quality of life (VRQoL) and objective performance-based measures in patients with primary open-angle, primary angle-closure, and pseudoexfoliation glaucoma; and 2) correlations between measurements of contrast sensitivity (CS) in specific areas of vision and visual field (VF) tests. : The Spaeth/Richman Contrast Sensitivity Test (SPARCS) measured CS in the inferior, superior, and central areas, while the Pelli-Robson test measured central CS. Visual fields were tested in participants using standard-automated perimetry.
