Frontotemporal Dementia and Eyes
Frontotemporal dementia (FTD) can affect the eyes, by causing outer retinal thinning. Retina is a layer at the back of the eye which sends visual signals to the brain. Research suggests that retinal thinning also happens in other neurodegenerative diseases, not only FTD. In addition, patients experience worse visual acuity - a reduced ability of the eye to differentiate between shapes and details at a given distance. These could potentially serve as disease biomarkers to diagnose FTD [1]. However, no specific ocular changes have been identified in the eyes of individuals with FTD postmortem. More research is needed to fully understand the impact of FTD on the eyes [1, 2].
