In a prospective, double-blind, randomized, clinical trial, glutathione bicarbonate Ringer’s (GBR) intraocular irrigation fluid was compared with Ringer’s solution in 80 consecutive vitrectomies, with a mean follow-up of 5.8 months. No differences could be found with regard to visual acuity, corneal edema, anterior chamber flare, postoperative intraocular pressure ≥ 30 mm Hg or phthisis bulbi. In this study, the superiority of GBR solution over Ringer’s solution demonstrated in vitro could not be confirmed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
