Arachnoid Cells (AC)

Arachnoid cells, also known as müller cells, are a type of cell in the eyeball. They have many important physiological and metabolic functions, including supporting retinal neurons, clearing dead cells and metabolites, maintaining the normal function of retinal blood vessels, and regulating the entry of light into the eye. They are the support and protector of the retina, and also one of the reasons for the emergence and development of some diseases in the eyes. Arachnoid cells have many special structures and functions. Their collagen fibers are rich in branches that pass through the retina to achieve true scaffolding. During development, arachnoid cells can promote normal retinal growth and neuronal development. After retinal injury, arachnoid cells can quickly clear injured and dead cells and metabolites, helping the retina recover quickly. There is a clear correlation between arachnoid cells and the occurrence and development of many retinal diseases. For example, in adolescent myopia and age-related macular degeneration, the retina undergoes changes, and the number and structure of arachnoid cells also change. In addition, arachnoid cells also play an important role in neonatal retinal injury, optic neuritis, and vitreous diseases. Therefore, a deep understanding of the structure and function of arachnoid cells is of great significance for the treatment and prevention of retinal diseases.
