Abstract
Objective: To estimate the magnitude of serious eye disorders and of visual impairment in a defined elderly population of a typical metropolitan area in England, and to assess the frequency they were in touch with, or known to, the eye care services. Design: Cross sectional survey using two stage cluster random sampling. Setting: General practices in north London. Subjects: Random sample of people aged 65 and older, drawn from a defined population of elderly people registered with 17 general practice groups. Main outcome measures: Proportions and population prevalence estimates were determined for visual acuity, assessed with the person's own spectacles (if any), classified into four categories: prevalence of cataract, age related macular degeneration, and refractive error causing visual impairment and of definite primary open angle glaucoma; and status of contact with eye services. Results: 1547 of 1840 (84%) eligible people were examined. The population prevalence of bilateral visual impairment (visual acuity Conclusions: Untreated visual impairment and eye disorders affect a substantial proportion of people aged 65 years and older. These findings should contribute to the setting up of future strategies for preservation of sight and eye health services in general. Data have not been adequate to reliably estimate the extent of visual impairment and serious eye disease in metropolitan areas in Britain Data from north London shows that 30% of a sample of the population aged 65 or older are visually impaired in both eyes More than 72% of the bilateral visual impairment was potentially remediable by surgery or glasses, nearly one in three people had visually impairing cataract, and 88% of these people were not in touch with eye services Eye problems were more prevalent in people living in relatively underprivileged areasKeywords
