Model Answer Unit 4, Activity 3.3, Step A, Visual Pathways
We noted down the following key findings of the study. Your notes might be different.
32.5% of people with dementia had visual acuity (VA), which refers to clarity of vision, worse than the legal standard for driving and 16.3 per cent had VA worse than the commonly used international standard for defining when someone is 'visually impaired'.
Almost 50% of those with VI were no longer classified as visually impaired when wearing their up-to-date spectacle prescription.
VI was approximately 2-2.5 times more common in those living in care homes than for those living in their own homes, even after age and gender had been controlled for.
Cataract and age-related macular degeneration (AMD) were the primary causes of VA.
16% of participants could not read standard newspaper-size print with their current spectacles, however almost two thirds of these participants could read this print wearing a prescription given following a dementia-friendly sight test.
