AnnotationThe prevalence of severe visual impairment increases from 14.3% for those aged 65 to 75, to 27.5% for those aged 85 and over. By age 75, almost 95% of the population requires some optical correction to maintain visual function, and more than 25% of over 85s has severe visual impairment. Such patients present special challenges in both evaluation and in working to maximise their usable vision. Performance on most common vision measures is affected by cognitive function, with ability to perform visual tasks at least partly resulting from the severity of the impairment. Although sensory loss is a well-known concomitant of ageing, its role as a determinant of patients' functioning is too often overlooked. Adequate assessment of vision is a first step toward understanding the role played by vision in the functioning of patients with cognitive impairment. (RH).
