متن کاملThe Relationship Between Visual Acuity and the Reproducibility of Visual Field Measurements in Glaucoma Patients.
PURPOSE The purpose of this study was to investigate the association between visual acuity (VA) and reproducibility of test-retest visual field (VF) measurements in glaucoma patients. METHODS Subjects were comprised of 627 eyes of 627 open-angle glaucoma patients. The reproducibility of two Humphrey VFs (24-2 or 30-2 Swedish Interactive Threshold Algorithm tests) examined twice within the per...
