Purpose
We evaluated the efficacy of topical brimonidine in visual field preser vation and/or improvement in eyes undergoing controlled glaucoma.
Methods
Seventy eyes of patients were trained with two different visual field test strategies: The Octopus Tendency Oriented Perimetry (TOP) G1 and the Frequency Doubling Technology (FDT) 30°. Following 2–4 months of brimonidine treatment, there were significant improvements in visual field, as assessed using the TOP G1 strategy (p = 0.003). The FDT 30° test revealed no statistically significant differences.
Conclusions
These data support the results of other studies, which indicate that brimonidine may increase mean sensitivity in visual field tests. Since it is known that the control of intraocular pressure does not fully protect glaucomatous eyes from visual field loss, it is possible that the neuroprotective qualities of brimonidine may contribute to visual field preservation in glaucomatous eyes.
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.
