The nervous system is divided into the peripheral nervous system and the central nervous system. Fortunately, damaged peripheral nerves can regenerate after injury. However, the optic nerve and the spinal cord are in the central nervous system, and unfortunately cannot regenerate after injury.This is thought to be a result of inhibitory factors that are produced by cells that normally support the nerve fibers.n goldfish, the optic nerve can regenerate after injury. Molecular factors involved in structural support, gene regulation, and nerve fiber growth are produced in the goldfish optic nerve after injury.
Summary of  Glaucoma and optic nerve repair..
