Introduction

Retinal Ganglion Cells In Neurodegeneration is an important component in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.

Retinal ganglion cells (RGCs) are the final output [neurons](/entities/neurons) of the retina, transmitting visual information to the brain. Their accessibility makes them important biomarkers for neurodegenerative diseases, as changes in RGC structure and function can reflect broader CNS pathology.
