Best practice treatment algorithm for primary open-angle glaucoma: implications for U.S. ophthalmology practice.

Abstract

The objective of this study was to develop a "best-practice" treatment algorithm for the management of primary open-angle glaucoma in patients receiving initial medical therapy, to serve as a consideration for future ophthalmology practice. For comparison, a baseline, "common-practice" treatment algorithm was also created that reflects current ophthalmology practice patterns. Survey instruments were developed based on a comprehensive review of relevant literature, along with input from a general ophthalmologist. A panel of eight ophthalmologists subspecialized in glaucoma management was surveyed. Consensus was achieved using a modified Delphi technique. A comparison of common- and best-practice treatment algorithms suggests that in contrast with expert opinion, nonselective beta blockers are currently used more often, and alpha-2 agonists less often, as first-line therapy for the treatment of primary open-angle glaucoma.
