The ganglion cell layer is a vital component of the retina, responsible for transferring information from the photoreceptor cells to the optic nerve. Other synonyms for this crucial layer of cells include ganglion cell nerve fiber layer, GCL, and simply the ganglion layer. While it's easy to overlook the importance of the ganglion cell layer, it's an essential part of our visual system that helps us to perceive images and interpret the world around us. Defects or damage to this layer can result in vision problems or even blindness, making it crucial to understand the function and structure of this key component of the retina.
