Abstract

The ability of fluorophotometry to measure the time course of changes in aqueous humor flow in rabbits was evaluated by measuring the effect of intravenous carbonic anhydrase inhibitors on aqueous humor flow determinations. The abrupt changes in aqueous humor flow which were found by fluorophotometry agreed well with the expected changes in aqueous humor flow calculated from the time course of the intraocular pressure. Therefore, it was concluded that fluorophotometry could measure the time course of changes in aqueous humor flow in rabbits. Furthermore, it was suggested that the initial abrupt changes in aqueous humor flow after the administration of a carbonic anhydrase inhibitor were induced by the base content of the drug, followed by a more gradual decrease in aqueous humor flow caused by the direct effect of the drug on aqueous humor formation.
