dcterms.abstract | Purpose: To explore whether subtle changes in visual quality can be detected using different measures of visual function against the quick contrast sensitivity function test (quick CSF). | - |
dcterms.abstract | Methods: Sixty participants, aged 17 to 34 years, were enrolled. Participants’ vision was degraded by 0.25 D undercorrection (0.25 D), 60% neutral density filter brightness reduction (60% ND), and 0.8 Bangerter foil optical diffusion (0.8BAN). Visual function tests including visual acuity and contrast sensitivity (CSV-1000E and quick CSF) were measured with participant’s best-corrected vision and under simulated visual degradation conditions. Test sensitivities in detecting differences were compared. | - |
dcterms.abstract | Results: Statistically significant visual acuity degradation was observed in the 0.8BAN condition only (Pcorrected < 0.001). With CSV-1000E and outliers removed, significant CS degradation was observed in all spatial frequencies, area under log CSF (AULCSF) in the 0.8BAN condition (Pcorrected < 0.001 for all), medium and high spatial frequencies and AULCSF in the 60%ND condition (Pcorrected, 6cpd = 0.002, Pcorrected, 12cpd = 0.005, Pcorrected, 18cpd = 0.001, Pcorrected, AULCSF < 0.001) and the 0.25 D condition (Pcorrected, 6cpd = 0.011, Pcorrected, 12cpd =0.013, Pcorrected, 18cpd =0.015, Pcorrected, AULCSF <0.001).With the quick CSF, significant CS degradation was observed in all simulated visual conditions in all spatial frequencies, cutoff frequency and AULCSF (Pcorrected < 0.001 for all). Test-retest reliability of the quick CSF method was high; coefficient of repeatability ranged from 0.14 to 0.18 logCS. | - |
dcterms.abstract | Conclusions: Compared with visual acuity and chart-based CS tests, the quick CSF method provided more reliable and sensitive measures to detect small visual changes. | - |
dcterms.abstract | Translational Relevance: The quick CSF method can provide sensitive and reliable measures to monitor disease progression and assess treatment outcomes. | - |
