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

摘要

Purpose: 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. Methods: 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. The National Eye Institute Visual Function Questionnaire (NEI-VFQ-25) assessed VRQoL, and the Compressed Assessment of Ability Related to Vision (CAARV) assessed vision-related performance. Results: Three hundred and twenty-two eyes of 161 participants were included in our analysis. Significant correlations were found between CS and VF scores in the inferior, central, and superior areas (P < .0001 for all). Significant correlations were found between SPARCS scores in the inferior areas in both eyes and most CAARV scores (P < .05). Significant correlations were also found between SPARCS scores in the inferior and superior areas in the worse eye and most NEI-VFQ ?25 scores (P < .05). Conclusion: Contrast sensitivity and VF scores significantly correlated in all tested areas. Reduced CS in the inferior areas of both eyes affected most performance-based measures. Measurement of CS areas using SPARCS is a meaningful way to assess VRQoL and ability to perform daily activities in participants with glaucoma.
