The epidemiology, economics and quality of life burden of age-related macular degeneration in France, Germany, Italy and the United Kingdom

Age-related macular degeneration (AMD) is a major public health issue, but little is known about the economics of the disease. This contribution describes the epidemiology and the economics of AMD in four European countries: France, Germany, Italy and the United Kingdom (UK). We reviewed published information on AMD, including guidelines, official statistics, and local literature and interviewed AMD experts. All available health-related quality of life studies (HRQoL) on AMD were also reviewed. Data collection focused on epidemiology, medical management and resource use (both medical and non-medical items). Prevalence of AMD among persons older than 65 years is 8% and increases with age. There are two forms of the disease: atrophic (80-85% of AMD cases) and exudative, which is characterised by choroidal neovascularisation (CNV; 15-20% of AMD cases). No treatment for the atrophic form is available. Laser photocoagulation is the mainstay of treatment for CNV, although less than 30% of persons with CNV can benefit from it. Photodynamic therapy (PDT), a new treatment for CNV, reduces the risk of vision loss in forms with predominantly visible lesions. Several other new procedures are also under development. Rehabilitation and low-vision aids are useful palliative interventions when there is a residual visual acuity. The yearly budget impact of AMD was found to be between 51.3 and 101.1 million euros in the four countries studied. Information on social services and resource use was scant and little is reported on the impact of AMD on HRQoL. Economic studies of AMD should be conducted in order to assist public health decision making.
