Shortened Measurement Time of Functional Visual Acuity for Screening Visual Function

Table 1

Comparison of the parameters of the functional visual acuity (FVA) test between the standard test and the short-version test (n = 28).

Parameters	Standard method (mean ± standard deviation)	Short-version method (mean ± standard deviation)	value
Distance-corrected FVA (logMAR)	−0.147 ± 0.030	−0.146 ± 0.035	0.931
Maximal visual acuity (logMAR)	−0.174 ± 0.022	−0.176 ± 0.019	0.785
Minimal visual acuity (logMAR)	−0.048 ± 0.062	−0.079 ± 0.069	0.036
Visual maintenance ratio	0.99 ± 0.02	0.98 ± 0.02	0.508
Average response time (seconds)	1.22 ± 0.12	1.22 ± 0.12	0.927

Wilcoxon signed-rank test; logMAR = logarithm of the minimal angle of resolution.
