PRECIS: Hemoglobin Video Imaging (HVI) provides a noninvasive method to quantify aqueous outflow (AO) perioperatively. Trabecular bypass surgery (TBS) is able to improve, and in some cases re-establish, conventional AO. PURPOSE: The purpose of this study was to use HVI to illustrate and quantify effects of TBS on AO through the episcleral venous system. DESIGN: This is a prospective observational cohort study. PARTICIPANTS: Patients were recruited from Sydney Eye Hospital, Australia. The study included 29 eyes from 25 patients, 15 with glaucoma and 14 normal controls. TBS (iStent Inject) was performed on 14 glaucomatous eyes (9 combined phacoemulsification/TBS and 5 standalone TBS). Cataract..View full abstract
