Abstract
|
|
|
Purpose: This study was aimed to investigate effects of breath alcohol concentration (BrAC) increase on visual field and readable visual field.
Methods: 23 males in 20s (average age 21.17±2.19 years, body mass index (BMI) 22.09±2.16) were selected and administered the amount of alcohol to reach 0.05% and 0.08% BrAC calculated by BAC (blood alcohol concentration) Dosing Software program. Then, visual field and readable visual field test with Vision Disk were conducted.
Results: Visual field are measured as 74.41±15.97o, 64.98±17.93o, and 58.33±19.01o (p=0.000) and readable visual field as
21.93±12.71o, 17.41±11.36o, 14.26±9.93o (p=0.006) in 0.00%, 0.05% and 0.08% BrAC respectively. As breath alcohol concentration increased, both visual field and readable visual field decreased.
Conclusions: BrAC increase with drinking could be the cause of safety accident by decreasing visual field and readable visual field, it is necessary to raise awareness.
