Table 2 Mean values for the disturbance index and pupil size for groups with BrAC ≤0.25 mg/l and BrAC > 0.25 mg/l.

From: A visual test based on a freeware software for quantifying and displaying night-vision disturbances: study in subjects after alcohol consumption

  BrAC ≤ 0.25 mg/l BrAC > 0.25 mg/l
  PRE- POST- PRE- POST-
VDI monocular 0.22 ± 0.10 0.30 ± 0.16 0.27 ± 0.17 0.44 ± 0.25
VDI binocular 0.16 ± 0.08 0.20 ± 0.11 0.16 ± 0.09 0.27 ± 0.17
Pupil size (mm) 5.2 ± 0.9 5.4 ± 1.0 5.3 ± 0.9 5.7 ± 0.9
  1. Mean values for the visual disturbance index (VDI) and for the pupil size before and after alcohol consumption for the two groups: BrAC≤0.25 mg/l and BrAC>0.25 mg/l. Standard deviation included. Statistical analysis: paired-sample t-Test for means.
