Estimating the cost of sight loss and blindness is essential if their socioeconomic impact is to be fully understood. Prevalence estimates relied on dated epidemiological studies and may not capture recent advances in treatment, or the substantial increase in the prevalence of age-related sight-impairing conditions due to demographic ageing, and associated increases in their costs.
Importantly, this study takes account of new data to update the understanding of the economic impact of sight loss and blindness in the UK, enabling international comparison and an estimate of the change over the five years between and Finally, this study highlights the need for population-based studies that track the prevalence of sight-impairing eye conditions and treatment effects over time.

Associated Data Data Availability Statement The data sets supporting the results of this article are available to the public from various government sources. Abstract Background To quantify the economic impact of sight loss and blindness in the United Kingdom UK population, including direct and indirect costs, and its burden on health. Methods Prevalence data on sight loss and blindness by condition, Census demographic data, data on indirect costs, and healthcare cost databases were used.
Results Sight loss and blindness from age-related macular degeneration AMD , cataract, diabetic retinopathy, glaucoma and under-corrected refractive error are estimated to affect 1. Conclusions The large prevalence of sight loss and blindness in the UK population imposes significant costs on public funds, private expenditure, and health. Electronic supplementary material The online version of this article Background Sight loss and blindness cause a considerable amount of health burden globally.
Methods The costing methodology used in this study is based on a prevalence approach to cost measurement [ 9 ]. Health care system expenditure- direct costs Direct health system costs were determined using a combination of a top down and bottom up approach. Indirect costs: There are two types of indirect costs of sight loss and blindness: the financial costs associated with lower productivity from premature mortality, lower workforce participation and absenteeism, and the cost of informal carers, aids and modifications and deadweight losses; and the non-financial costs from loss of healthy life, that are analysed in terms of disability adjusted life years DALYs.
Results Prevalence In , there were an estimated 1. Open in a separate window. Burden of disease Using disability weights from the global burden of disease project for comparison with the estimates and older international studies, the YLDs lost due to sight loss and blindness were estimated as , , to , DALYs in the UK in Conclusion Estimating the cost of sight loss and blindness is essential if their socioeconomic impact is to be fully understood.
