Glow in the dark eye drops to save your sight: New test could detect glaucoma ten years before symptoms appear

  • New test could potentially save the sight of millions of people
  • The technology detects dying nerve cells in the eye
  • Uses fluorescent compound that makes the back of the eye ‘glow’

Scientists are developing a new test that could detect glaucoma ten years before symptoms appear – and potentially save the sight of millions of people.

The technology, which detects dying nerve cells in the eye, has the potential to identify other neurological conditions at an early stage, such as Alzheimer’s and Parkinson’s.

Glaucoma is the leading cause of preventable blindness in the world and affects 500,000 in Britain, though experts warn many more could be undiagnosed.

The test, which is being trialled for the first time in humans at the Western Eye Hospital in London, uses a type of fluorescent compound that makes the back of the eye ‘glow’ if glaucoma is present.

Glaucoma is caused when drainage tubes in the eye become blocked and fluid starts to build up in the eyeball. This leads to high pressure, causing damage to the optic nerve (which carries signals from the eye to the brain) and irreversible blindness……….
