The relationship between visual field loss in glaucoma and health-related quality-of-life
Eye , Volume 24 - Issue 12 p. 1759- 1769
Purpose: To investigate the relationship between visual field loss and health-related quality-of-life (HRQOL) in patients with ocular hypertension (OHT) or primary open-angle glaucoma (POAG). Methods: We conducted a cross-sectional study among 537 OHT and POAG patients from seven hospitals in The Netherlands. Clinical information was obtained from medical files. Patients completed a questionnaire, containing generic HRQOL instruments (EQ-5D and Health Utilities Index mark 3), vision-specific National Eye Institute Visual Functioning Questionnaire (VFQ-25), and glaucoma-specific Glaucoma Quality-of-Life questionnaire (GQL-15). The impact of visual field loss on HRQOL scores was analysed with multiple linear regression analyses. Results: A relationship between mean deviation (MD) and HRQOL was found after adjusting for age, gender, visual acuity, medication side effects, laser trabeculoplasty, and glaucoma surgery. We found interaction between MD in both eyes for GQL and VFQ-25 scores. The relationship between MD and utility was non-linear, with utility only affected at MD-values below 25 dB in the better eye. Visual acuity, side effects, and glaucoma surgery independently affected HRQOL. Binocular MD and MD in the better eye had similar impacts on HRQOL, whereas MD in the worse eye had an independent effect. HRQOL was affected more by binocular defects in the inferior than in the superior hemifield. Conclusion: Visual field loss in progressing glaucoma is independently associated with a loss in both disease-specific and generic quality-of-life. It is important to prevent progression, both in early and in advanced glaucoma, especially in patients with inferior hemifield defects and severe defects in either eye.
