Abstract : Injuries of the mammalian central nervous system (CNS), which includes the axons of the retinal ganglion cells, result in axonal degeneration and irreversible loss of function. This is the reason for the failure to transplant neuroretina or other parts of the CNS, and also explains the permanent disablement resulting from injuries to the brain and spinal cord. The use of low-energy helium-neon (He-Ne) laser irradiation has recently attracted attention concerning the treatment of nerve injury. Studies in the rat optic nerve have yielded several key observations which support the notion that treatment with low-energy laser is beneficial to injured rat optic nerves, provided that all parameters are well-calibrated and optimal. Below is a summary of our major results in two major aspects: (i) in delaying degeneration or rescuing marginally injured nerves; and (ii) in supporting regrowth when combined with an additional treatment modality. pg4.
