An LED technique that identifies molecules within the eye that occur during the formation of cataracts has been developed by scientists at Heriot-Watt University in Edinburgh.
Using new biochemical information, the technique allows clinicians to examine a florescence signal from proteins in the eye.
By documenting the changes to the photochemistry of the eye during cataract formation, an objective scale for diagnosis can be created which could save global health services millions annually.
Head of the institute for biological chemistry, biophysics and bioengineering at Heriot-Watt University Professor Rory Duncan said: ‘Rather than waiting for the condition to appear, it could be possible to diagnose and monitor cataract before it forms, allowing preventative measures to be taken where possible.’
Scientists from Heriot-Watt University worked with Edinburgh Biosciences LTD, clinical experts from Edinburgh University and partner organisations in Sweden and Denmark to develop the technique.
Research co-founder Professor Des Smith said: ‘This research brings us one step closer to developing a non-invasive treatment for cataracts.’
The team are in the process of raising further funds to transfer the technology into clinical trials, which would determine whether non-invasive cataract treatment is feasible.
