The risks of developing dementia and visual impairment both increase with age. However, prior to the PrOVIDe study, there was limited data about the prevalence of visual impairment in people with dementia in the UK.
The PrOVIDe study was designed to better understand how prevalent visual impairment is in people with dementia, and compare this to levels within the wider population of older people. It also aimed to identify the extent to which visual impairment is undetected or inappropriately managed in people with dementia and how eye care can be improved for them. This study included people with dementia who live in their own home as well as those in care homes.
