New tool may spot eye diseases early

A new tool may enable people to diagnoses eye disease early, often before symptoms have even developed, according to experts.

Specialists at the Massachusetts Eye and Ear Infirmary, Department of Ophthalmology at Harvard Medical School in Boston showed that they have created a noninvasive tool that detects signs of disease at early molecular stages before symptoms can be seen using traditional methods.

Dr Ali Hafezi-Moghadam, co-author of the study, said that its use may well extend to other areas of the body in the future, and it may also give physicians a more precise way of evaluating the effectiveness of therapies.

"Quantitative knowledge of the dynamic molecular changes in health and disease will not only advance our understanding, but also change the way medicine will be practiced in the future," he said.

It follows a study by Dr J William Harbour, an ophthalmologist at Washington University School of Medicine in St Louis, Missouri, who has been implanting radioactive discs in the eyes of children with a rare cancer in an attempt to save their sight and eyes.
