Factors associated with visual field or structure progression occurring first in a prospective study on patients with untreated open-angle glaucoma with normal intraocular pressure

Background/Objectives To identify factors associated with disc/retina deterioration in stereo fundus photographs preceding that of the visual field (VF), as determined with a Humphrey Field Analyzer (HFA) (Structure First deterioration) and factors associated with the latter preceding the former (Field First deterioration) in open-angle glaucoma (OAG) with lower normal intraocular pressure (IOP). Subjects/Methods Prospective cohort study. Ninety eyes of 90 patients with OAG and a baseline IOP
