Studies of aqueous humor dynamics in man. I. Measurements in young normal subjects.

Abstract

Aqueous humor dynamics can be defined in terms of intraocular pressure, episcleral venous pressure, true facility, pseudofacility, and aqueous flow through the eye. With the use of cooperative subjects, the measurements can be made repetitively and are reproducible with small standard errors. In addition, good agreement between right and left eyes allows examination of pharmacologic agents on one eye as compared with the other eye. Application of this technique to a study of the mechanism of the topical steroid response of intraocular pressure indicated that the elevated intraocidar pressure is related only to a significant reduction in true outfloio facility.
