Biomarker indicating neurodegeneration identified in the eye

A new study indicates a well-known biomarker that serves as a marker for earlier diagnosis of neurodegenerative diseases is now detectable in the eye. Neurofilament light chain, a protein previously detected in cerebrospinal fluid and blood that is being explored as a biomarker to detect neurodegeneration, has now been identified in the vitreous humor, or fluid within the eye.
