Abstract
|
|
|
Purpose: This study was designed to investigate the changes of vision and ocular functions induced by increase of blood alcohol level.
Methods: Blood alcohol level, vision, refractive errors, near point convergence, heterophoria, and relative convergence were measured at 1h, 4h, and 24h after acute alcohol ingestion of 0.7g per kg body weight.
Results: At 1h after alcohol ingestion, myopization and ocular functions which measured near point convergence, positive and negative convergences, and degree of heterophoria remarkedly worked a changes accompanied with the maximum value of blood alcohol level. But at 24h after that, all of ocular functions were recovered to degree of 90~99% compared with non-alcoholic normal conditions.
Conclusions: As the increase of blood alcohol level is able to induce the significant changes of visual acuity and ocular functions, opticians have to understand thoroughly the patient’s conditions by alcohol ingestion before refractive test and ocular examinations.
