A new study has revealed a stark warning for the future of eye health in the UK. Researchers predict that the number of people living with glaucoma, the leading cause of irreversible blindness worldwide, will rise to 1.6 million by 2060 – a staggering 60% increase from current estimates.
The sharp rise will be driven by the country’s ageing population and a growing proportion of higher-risk ethnic minority groups, highlighting the urgent need for expanded eye health services to meet the expected demand. Currently, it is estimated that over 1 million people in the UK have glaucoma, representing 3% of the population over 40. However, this figure is projected to rise to 4% among people of African descent and a concerning 11% in those over 85.
“Glaucoma is a common cause of blindness, but it isn’t symptomatic until its later stages, so regular tests are important for early diagnosis,” explained Professor Paul Foster, the study’s lead author and a researcher at UCL Institute of Ophthalmology. “Previous studies have estimated that half of glaucoma cases are undiagnosed, and this is even higher among some ethnic minority groups who are more likely to experience delays in diagnosis.”
Late diagnosis is a significant issue, as it comes with a higher risk of sight loss and increased costs of care. Over 40% of glaucoma patients in the UK experience vision loss that could have been prevented with earlier diagnosis and treatment, such as eye drops or surgery.
Joanne Creighton, the chief executive of Glaucoma UK, which commissioned the research, warned that this “demographic timebomb” requires urgent action. “Many of the 1 million adults estimated to have glaucoma would not know they had the condition, and potentially lose sight that they would never be able to recover,” she said.
The findings underscore the need to expand ophthalmology services and ensure people have access to specialist eye care. Awareness campaigns encouraging regular eye checks are also crucial, particularly in reaching underserved and hard-to-reach populations.
“Our findings show that there will be a large increase in glaucoma cases in the UK, so there’s a growing need to expand eye health services to meet this demand, including specialist care and diagnostic capacity,” said Professor Foster.
For those in midlife and beyond, the message is clear: get your eyes checked annually by an optician to detect changes that haven’t yet caused any symptoms. Early detection and treatment are key to preventing irreversible vision loss from this insidious condition.
