Relationship between Preferred Sleeping Position and Asymmetric Visual-field Loss in Open-angle Glaucoma Patients – Accepted Manuscript
Abstract: Purpose: To investigate the relationship between preferred sleeping position and asymmetric visual-field (VF) loss in open-angle glaucoma (OAG) patients.Design: Retrospective, cross-sectional study.Methods: Six hundred and ninety-two (692) patients with bilateral normal-tension glaucoma (NTG) or high-tension glaucoma were consecutively enrolled.
