Abstract

|
|
Purpose: To study the relationship between temporary refractive errors and changes in optical components in eyes after alcohol ingestion.
Methods: Sixteen men of 23.8±2.2 years ingested the alcohol (0.70 g/kg body weight). Refractive errors, corneal thickness, corneal eccentricity, corneal curvature, pupil size, intraocular pressure, and length of ocular axis were measured at 1 h, 4 h, and 24 h after alcohol ingestion, and all values were compared with those of before ingestion.
Results: At 1 h after alcohol ingestion, refractive errors showed more myopic (p<0.001), corneal curvature increased, and both pupil size and intraocular pressure decreased significantly (p<0.05, p<0.01). Length of ocular axis was longer than before alcohol ingestion.
Conclusions: Alcohol ingestion can temporarily induce the more myopic errors through changes of corneal curvature and length of ocular axis compared with non-alcoholic condition.
