Acute ocular hypertension disrupts barrier integrity and pump function in rat corneal endothelial cells.

ABSTRACT: Acute ocular hypertension (AOH) frequently compromises corneal endothelial cell (CEC) function in clinical practice. This type of stress induces corneal oedema and a decrease in the corneal endothelial cell density (ECD). The anterior chamber of the right eye of Sprague-Dawley rats was irrigated with Balanced Salt Solution (BSS) for two hours, and the left eye served as a control to determine the time-dependent effects of AOH on endothelial cell morphology and function. The average intraocular pressure (IOP) increased to 82.6 ± 2.3 mmHg (normal range: 10.2 ± 0.4 mmHg) during anterior irrigation. Very soon after initiating irrigation, corneal oedema became evident and the cornea exhibited a significant increase in permeability to FITC-dextran. The peripheral ECD was significantly reduced, a
