A new low-cost and non-invasive eye test could detect Parkinson’s disease before symptoms including tremors and muscle stiffness develop, according to new research in rats led by scientists at UCL.
Researchers at the UCL Institute of Ophthalmology have discovered a new method of observing changes in the retina which can be seen in Parkinson’s before changes in the brain occur and the first symptoms become evident.
Using ophthalmic instruments that are routinely used in optometrists and eye clinics, the scientists were able to use the new imaging technique to observe these retinal changes at an early stage.
