TL;DR

This cross-sectional study of 133 eyes from visually impaired patients found significant correlations between colour vision test scores and other visual function measures like visual acuity, contrast sensitivity, and photostress recovery time across various underlying eye diseases.

This cross-sectional study examined 133 eyes from 133 visually impaired patients to explore correlations between colour vision tests (K-colour, HRR, Ishihara) and other psychovisual parameters: visual acuity, contrast sensitivity, and photostress recovery time (PSRT). The authors suggest colour vision tests could serve as a useful clinical surrogate for functional vision assessment.

ABSTRACT

Abstract Background: To investigate the correlation of colour vision, visual acuity, contrast sensitivity, and photostress recovery time test scores in visually impaired patients. Materials and methods: A total of 133 subjects were enroled and 133 eyes were examined. The pathological group consisted of 76 (57.1%) males with an average age of 68.0 (SD=13.2) and 57 (42.9%) females, with an average age of 68.1 (SD=15.2), Mann–Whitney U test was used to evaluate the differences in K-colour tests, HRR, visual acuity, Contrast Sensitivity test and photostress recovery time test between two different groups of severity. Results: Correlations were found among colour vision tests, visual acuity, contrast sensitivity, and photostress recovery time scores in eyes with age-related macular degeneration, with diabetic retinopathy, with optic nerve diseases, and various other retinal diseases ( P <0.05). In patients with moderate-visual impairments. Conclusions: The colour vision test scores correlate with the scores of visual acuity, contrast sensitivity, and photostess recovery time test. It may be a useful clinical surrogate for functional vision. Keywords: colour vision test, contrast sensitivity, K-colour test, PSRT test, visual impairement
