Topically applied (eyedrop) H 2 17 O (10% enrichment) was used in magnetic resonance studies to quantify intraocular water dispersion in vivo . The rate of H 2 17 O removed from the aqueous chamber is in the order of 0.1 ml/min/ml of tissue. Similar results are obtained with either proton imaging or 17 O spectroscopy. Parallel experiments of direct injection of H 2 17 O into the aqueous chamber supported the topical data. Proton MR imaging of H 2 17 O dissipation from the aqueous chamber with clinical imagers, coupled with eyedrop application. suggerts clinical possibilites. © 1991 Academic Press, Inc.
