Paper Abstract

The use of low-energy helium-neon 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. Irradiation employing a nonoptimal parameter could have either a devastating effect or no effect at all. Most laser irradiation studies using calibrated parameters have employed an electrophysiological setup in which measurements of compound action potential are carried out 2 weeks after injury. After this time period the electrophysiological activity of the injured treated nerve itself is very low, so that any beneficial effect resulting from any treatment is detectable.
