Individuals eligible for National Health Service (NHS) sight tests who are unable to attend a community optical practice unaccompanied due to disability are entitled to NHS General Ophthalmic Services (GOS) domiciliary eye examinations. The numbers of domiciliary NHS sight tests have increased substantially in recent years, and this trend may continue with the ongoing ageing of the UK populace. Patients receiving domiciliary eyecare are a vulnerable group, many of whom will have significant healthcare needs, and some adaptations to routine practice are required for the successful provision of mobile optometric services. This article will review recent national data linked to housebound individuals and the ageing population, before exploring the topic of preventable visual impairment in the UK and approaches to delivering a high standard of care to this diverse patient group.
