Participants were recruited between September 2013 and March 2015 from the Glaucoma Center of Excellence at the Wilmer Eye Institute, Johns Hopkins University to participate in the Falls in Glaucoma Study (FIGS). The research followed the tenants of the Declaration of Helsinki. Informed consent was obtained from study participants after an explanation of the nature and potential consequences of the study, and the research was approved by the Institutional Review Board at Johns Hopkins Hospital. Inclusion criteria were: (1) age 57 or older; (2) glaucoma suspect or diagnosis of primary open angle glaucoma, primary angle closure glaucoma, pseudoexfoliation glaucoma, or pigmentary glaucoma; (3) residence within a 60-mile radius from the Wilmer Eye Institute; (4) ability to perform VF testing; and (5) ability to complete at least 1 balance test. Glaucoma suspects, in addition to patients with a glaucoma diagnosis, were included in the study to determine the relationship between VF damage and balance over the full spectrum of VF loss (with suspects capturing balance in persons with little to no VF loss). Glaucoma diagnoses were determined by a glaucoma specialist following a comprehensive eye exam, including best corrected visual acuity, slit-lamp biomicroscopy, dilated fundus exam, VF analysis (Humphrey Field Analyzer II; Carl Zeiss Meditec, Inc., Dublin CA), and optical coherence tomography (Cirrus HD-OCT; Carl Zeiss Meditec). We reported baseline data obtained before collection of falls assessment data.
