Measuring retinal nerve fiber layer thickness (RNFLT) at specific locations will allow for early detection of cognitive decline and early treatment.
Why this matters
RNFLT in the eyes can allow for early detection of central nervous system (CNS) degeneration, such as dementia, using optical coherence tomography (OCT).
RNFLT has been shown to decrease with age in healthy individuals, as well as those with poorer cognitive abilities.
Currently, therapeutic options for dementia are very limited; therefore, screening via RNFLT is important to detect dementia at an early stage.
