Impact of Visual Impairment on Vision-Specific Quality of Life among Older Adults Living in Nursing Home. (March 2014) - Dev, Mahesh Kumar
Abstract Background: Visual impairment (VI) has a significant negative impact on quality of life (QoL) amongst older people living in nursing homes. The purpose of this study was to determine the prevalence of VI and blindness and to explore the association between severity of VI and vision-specific QoL among older people living in nursing homes of Kathmandu, Nepal. Methods: This cross-sectional study involved 158 residents aged 60 years or older residing in seven nursing homes of Kathmandu Valley, Nepal. Near acuity, presenting and the best corrected distance visual acuity (VA) were assessed in each eye and considered in the better eye after adequate refraction. A complete anterior and posterior segment examination was carried out. Face-to-face interviews were conducted using a 57-item Nursing Home Vision-Targeted Health-Related Quality of Life (NHVQoL) questionnaire. Results: The mean age of residents was 75.60 ± 7.12 years and the majority were female (66.46%). The prevalence of VI and blindness was 45.57% and its leading cause was cataract, which was followed by age-related macular degeneration, corneal opacity, glaucoma and macular scar. The mean composite score of NHVQoL questionnaire was 52.22 ± 12.49. There was a consistent overall deterioration in the mean composite score as well as each subscale score of NHVQoL questionnaire with a worsening of VA. Conclusion: VI and blindness are highly prevalent among older people living in nursing homes. VI has a significant negative impact on vision-specific QoL. Vision-specific QoL is reduced, and the reduction in the QoL bears a positive association with severity of VI among older people living in nursing homes.
