Leading cause of irreversible blindness and severely impaired eyesight age-related macular degeneration (AMD) for short is expected to affect 77 million Europeans by 2050
Number of people with the leading cause of blindness will increase by 10million in Europe by 2050 because people are living longer, reports a new study. The findings of the study are published in the British Journal of Ophthalmology.// The leading cause of sight loss could affect 77 million Europeans by 2050, researchers have said. This will require considerable extra healthcare resource and careful planning for decades to come, particularly as most cases will be in people aged 70+, warn the researchers.
AMD occurs when the small central portion of the retina, the light-sensing tissue at the back of the eye (macula), deteriorates with age. When advanced, it can be treated, but not cured.
To try and come up with an accurate estimate of the likely demands placed on healthcare services by AMD, the researchers calculated the numbers of existing (prevalent) and new (incident) cases across member states of the European Union (EU) up to the year 2050.
To do this, they pooled data from 22 prevalence (existing disease) studies involving 55,323 people, aged, on average, between 60 and 81, and from four incidences (new cases) studies from across Europe. The resulting analysis showed that the number of existing cases is projected to rise by 15%, while the number of new cases is projected to rise by 75% up to 2050.
By that date, the estimated projections show that one in four older adults in the EU will have AMD, ranging from just under one in 10 of those younger than 65 to just under 27% of those over the age of 75. And the proportion of those with advanced AMD will be just under 2.5% for all older ages combined; the calculations show.
To calculate the figures for new cases of advanced AMD, the researchers pooled the data for 7223 study participants from the four incidence studies.

Based on these figures, they estimate that 77 million people in the EU will have AMD by 2050, compared with 67 million as of 2015.

And the numbers of new cases of advanced AMD will increase from 400,000/year to 700,000 by 2050, with the highest numbers of such cases in Germany.
The researchers caution that most of the included studies came from Western Europe, so the findings may not be applicable to Eastern European countries. And the periods during which new cases were identified varied across the included studies, which may have affected the precision of the estimates they calculated.
Nevertheless, they estimate that both existing and new cases of all stages of AMD will steadily increase in Europe until 2050.
"This will require considerable additional healthcare service and resource allocation, which should be considered already today in all European healthcare systems," they warn.
