The Prevalence of Visual Impairment in People with Dementia (the PrOVIDe study): a cross-sectional study of people aged 60-89 years with dementia and qualitative exploration of individual, carer and professional perspectives

National Institute for Health Research, July 2016

This study aims to measure the prevalence of eye conditions causing visual impairment in people with dementia and to identify/describe reasons for under-detection or inappropriate management.

The study concludes that prevalence of visual impairment is disproportionately higher in people with dementia living in care homes. Almost 50% of presenting VI is correctable with spectacles, and more with cataract surgery. Areas for future research are the development of an eye-care pathway for people with dementia; assessment of the benefits of early cataract surgery; and research into the feasibility of specialist optometrists for older people.
