Researchers developing eye tests to evaluate diabetic neuropathy receive global recognition

Researchers from QUT's Institute of Health and Biomedical Innovation (IBHI) developing eye tests to assess diabetic neuropathy and pave the way for earlier treatment are key partners in a consortium awarded $US1.1 million from the leading American medical research agency.

The US National Institutes of Health is the largest source of funding for medical research in the world. The grant for this project supports a research collaboration involving six universities worldwide, including QUT.

Professor Nathan Efron from IHBI's School of Optometry and Vision Science, who leads the QUT research team with Dr Nicola Pritchard, said the funding would link them with other leading laboratories to share knowledge and further advance the development of eye tests to identify diabetic neuropathy, a painful condition experienced by up to 50 per cent of people with type one diabetes.

"We will work with researchers from around the world to find out if we can examine the nerves in the front of the eye with specialised examination equipment to identify/predict diabetic nerve damage long before it becomes apparent in other parts of the body," said Professor Efron who has also just been awarded the prestigious Kenneth W Bell Medal from the Cornea and Contact Lens Society of Australia (CCLSA).

"The project involves QUT and institutions in Canada, the US, UK and Qatar and brings together researchers from optometry, ophthalmology, endocrinology, neurology and histology.

"This is an exciting project as one of the key aims is to pool research data from the participating centres so that information from over 600 diabetic patients world-wide can be assembled to help answer some key questions relating to the performance of these new eye tests.

"This research will accelerate the development of these novel eye tests for diabetes, and may result in the widespread deployment - perhaps within the next 5 years - of highly specialised instruments around Australia that can be used to take these measurements."

Professor Efron said typical symptoms of diabetic neuropathy can include numbness, pins and needles, tingling, discomfort, or weakness, which usually begin in the hands or feet and spread up the arms and legs. For many it results in significant pain and discomfort, especially at night, and can also cause balance problems and damage and deformity to feet.

"Early diagnosis can reduce complications and help with pain management, and some of our recent data suggests that regrowth of damaged nerves is possible under certain conditions" he said.
