Corneal swelling.
This article is also accessible online at: http://BioMedNet.com/karger Dear Sir, A recent study of corneal swelling by Aakre and Doughty [1] found two regimes in the time course of tissue fluid imbibition. We are pleased to note that this confirms our discovery made over 10 years ago at the University of New South Wales, Sydney [2, 3]. We first reported these results in 1986–1988 to meetings of...
متن کاملStromal acidosis modulates corneal swelling.
PURPOSE Studies have shown that stromal acidosis reduces the rate of corneal thickness recovery after induced edema, providing the first human in vivo evidence that corneal pH can influence corneal hydration control. This finding raises the question of the possible effect that pH may have on induced corneal swelling. To explore this question, the corneal swelling response to hypoxia was measure...
متن کاملCorneal swelling at low atmospheric oxygen pressures.
Corneas of 28 human subjects were exposed to oxygen partial pressures, in a gas goggle, of either 6.9, 17.1, or 22.2 mm Hg, and the corneal swelling was measured by pachometry for 4 hr. Following an initial rise, the swelling stabilized after about 3 hr; in many subjects it was reversed, indicating an adaptation process. The average corneal swelling after 4 hr for the three oxygen partial press...
متن کاملUneven swelling of the corneal stroma.
The surface V3 of the denuded corneal stroma was separated into the anterior and posterior segments; the swelling ratio of each was compared under zero pressure. In the rabbit, cat, and bovine corneas, the anterior segment was less hydrophilic than the posterior one, in both the central and peripheral regions. In the rabbit cornea, the swelling ratio of the posterior segment was significantly l...
متن کاملCorneal swelling at low atmospheric oxygen pressures
both cornea and conjunctiva occurred as early as 15 min after bacterial inoculation. By 1 to 3 hr after bacterial inoculation, shrinkage of corneal epithelial cells was pronounced (Fig. 5, a and b). Fewer microvilli were seen on the shrunken regions of these affected cells, and the cell surfaces appeared roughened and irregular. Additionally, intercellular junctions were dilated to 1.0 fim in d...
