The effects of varying hydrostatic pressure on the thinning rate of preswollen de-epithelialized or de-endothelialized corneas has been determined in the specular microscope. The appropriate membrane was removed, the cornea given access to Ringer to swell, and then fluid exchange at that surface blocked with oil. De-epithelialized corneas thin more slowly as hydrostatic pressure on the posterior surface is increased, until fluid movement ceases at 60 to 70 mm. Hg. Fluid movement can occur, therefore, against a considerable hydrostatic pressure. De-endothelialized corneas thin at a higher rate as hydrostatic pressure is increased; this effect is probably a mechanical one with increasing pressure forcing fluid out across the epithelium.
在镜面显微镜下已测定了不同静水压力对预肿胀的去上皮或去内皮角膜变薄速率的影响。去除相应的膜，使角膜接触林格液以肿胀，然后用油封闭该表面的液体交换。随着后表面静水压力的增加，去上皮角膜变薄的速度更慢，直到在60至70毫米汞柱时液体流动停止。因此，液体可以在相当大的静水压力下流动。随着静水压力的增加，去内皮角膜以更高的速率变薄；这种效应可能是一种机械效应，压力增加迫使液体穿过上皮流出。
