Photoreceptor cells in Parkinson's Disease represent an emerging area of research focusing on visual system involvement in neurodegenerative disorders. While Parkinson's disease (PD) is primarily characterized by motor symptoms, growing evidence indicates that visual disturbances are common non-motor manifestations, often preceding motor diagnosis by years.

The retina provides a unique window into the brain, and photoreceptor cells—rods and cones—have been increasingly studied in the context of Parkinson's disease. Research has revealed that:
