Although it has been suggested that glaucoma is associated with circadian misalignment, sleep disorder, anxiety, and depression, these comorbid conditions have not received much attention. This study provides evidence for a significantly higher prevalence of depression, trait anxiety, and sleep disturbances in patients with progressed glaucoma, as compared with glaucoma patients with no or minor visual field defects (VFD). Logistic-regression analyses suggest that severe VFD constitute a significant predictor of depression, trait-anxiety, and sleep disturbance. Results indicate the necessity of regular screening and psychochronobiological treatment in glaucoma patients.
