The relationship between retinal nerve fiber layer thickness and cognitive performance

Takeaway

  • 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.
