Earlier Diagnosis of Glaucoma – and Possibly Many Neurodegenerative Diseases – By Retinal Examination? (BBC News / NHS Choices / Brain)


A fluorescent dye injected into the bloodstream may, in future, provide a convenient method of detecting glaucoma earlier – perhaps a decade before more overt symptoms and damage have had the opportunity to develop – by identifying changes in the retina during routine eye examinations.

This new imaging technique, termed Detection of Apoptosing Retinal Cells (DARC), shows early promise as a convenient biomarker for a range of other neurodegenerative diseases, possibly offering a non-invasive means of earlier diagnosis and improved monitoring of disease progression for dementia, Parkinson’s Disease, multiple sclerosis etc.
