This study recorded the effects on ocular pressure of drinking a half liter of water in 5 min. Of the 324 subjects, treated or nontreated, presenting an ocular pressure greater than 18, the results after 15 min were as follows: a pressure rise between 3 and 4 points in 28.5% of the cases; a rise of between 5 and 6 points in 13.5% of the cases and, in 8% of the cases, a rise of more than 6 points. These figures were approximately the same for all ages and, to a lesser degree, for subjects at risk with normal ocular pressures. This transitory variation in pressure which recurs with the ingestion of liquids during meals might play an aggravating role in cases of glaucoma-induced nerve head ischemia with or without high ocular pressure.
本研究记录了5分钟内饮用半升水对眼压的影响。在324名眼压高于18的受试者（无论是否接受治疗）中，15分钟后的结果如下：28.5%的病例眼压升高3至4个点；13.5%的病例眼压升高5至6个点；8%的病例眼压升高超过6个点。所有年龄段的这些数据大致相同，眼压正常的高危受试者的数据差异较小。用餐时摄入液体后反复出现的这种短暂眼压变化，在伴有或不伴有高眼压的青光眼性神经乳头缺血病例中可能起加重作用。
