A simple and economical eye test could soon be able to detect and diagnose major neurological diseases such as Alzheimer's, much before than is currently possible, according to new research by UCL scientists.

Led by Professors Francesca Cordeiro and Stephen Moss, the study puts forward a new technique that enables retinal, and therefore brain cell death, to be directly measured in real time. The method, which was demonstrated in an animal model, could not only refine diagnosis of neurodegenerative disorders and help track disease progress, but it could also aid the assessment and development of new treatments.

The technique uses fluorescent markers that attach themselves to the relevant cells and indicate the stage of cell death. The retina is then observed using a customised laser ophthalmoscope. Until now, such technique has only been used in cells in the lab, rather than in live animals. (Lees meer...)
