Comparison of vision-related quality of life in primary open-angle glaucoma and dry-type age-related macular degeneration.

PurposeTo compare quality of life (QoL) in patients with primary open-angle glaucoma (POAG) and dry-type age-related macular degeneration (AMD) with similar best-corrected visual acuity.MethodsAge-, sex-, and visual acuity-matched POAG and dry AMD patients were included in the study. Each patient performed 24-2 and 10-2 SITA standard visual field tests. Contrast sensitivity was evaluated with CSV-1000 HGT instrument. The 25 item National Eye Institute Visual Function Questionnaire (NEI-VFQ-25) was used to analyze QoL. Overall and subscale scores were converted to scores between 0 and 100, the higher scores indicating better vision-related QoL.ResultsOverall NEI-VFQ-25 scores were 86.44 and 84.66 in glaucoma and AMD groups, respectively (P=0.244). The highest scores were obtained in 'vision-related dependency' subgroup in glaucoma and 'color and peripheral vision' in AMD group, whereas the lowest scores were noted 'in peripheral vision' in both glaucoma and AMD patients. Glaucoma patients had significantly lower scores in ocular pain, color vision, and peripheral vision subgroups compared with the AMD group, whereas AMD patients had lower scores in near and distance vision activities, vision-related social activity, and dependency subgroups. Contrast sensitivity results and mean defect values showed correlation with NEI-VFQ-25 scores in both groups.ConclusionsGlaucoma and AMD patients with similar visual acuity experienced similar overall impairment in QoL. However, glaucoma patients described more difficulty with peripheral vision and ocular pain, whereas AMD patients complained more about near and distance vision and dependency items.
