While considerable study and clinical speculation has been given to tear pH, almost no attention has been paid to the buffering capacity of this fluid. Responses of tears to an alkaline challenge test as a measure of their buffering capacity are described here for a series of patients. The magnitudes of those resulting shifts, and the probable mechanisms influencing them are commented upon.
虽然对泪液pH值已进行了大量研究和临床推测，但几乎没有人关注这种液体的缓冲能力。本文描述了一系列患者泪液对碱性激发试验的反应，以此作为其缓冲能力的一种衡量指标。对这些变化的幅度以及影响它们的可能机制进行了评论。
