MEASURING AQUEOUS HUMOR OUTFLOW

摘要

Technologies are provided to estimate in vivo aqueous humor outflow for a subject. The method can include: preparing a virtual casting of the outflow network of the subject by use of background subtraction and contrast enhancement; tracing network terminal branches in said reduced virtual casting; obtaining Doppler data for at least some of the terminal branches, to calculate a fluid velocity within each of such terminal branch; then pairing each fluid velocity for each such terminal branch with a measurement of cross-sectional area for that terminal branch, thereby to provide a plurality of volumetric flow values; and integrating over the plurality to obtain a volumetric estimate of aqueous humor outflow for the subject.

1. A method for estimating in vivo aqueous humor outflow for a subject, comprising the steps of:
(A) preparing a virtual casting of the outflow network of said subject by use of background subtraction and contrast enhancement; (B) tracing network terminal branches in said virtual casting; (C) obtaining Doppler data for at least some of said terminal branches, to calculate a fluid velocity within each of such terminal branches; then (D) pairing each fluid velocity for each of such terminal branches with a measurement of cross-sectional area for that terminal branch, thereby to provide a plurality of volumetric flow values; and (E) integrating over said plurality to obtain a volumetric estimate of aqueous humor outflow for said subject.
