Low energy laser effects on the visual system

Research output: Contribution to journalConference articlepeer-review


Low energy laser irradiation at subthershold energies has various effects on the eye and other body systems. The known bioeffects in the visual system are manifested mostly in retinal and other ocular tissues morphology. The only ophthalmic low energy laser irradiation effect which has been adequetely and thoroughly studied and analysed is its degeneration postponing activity on the crushed rodent optic nerve. This bioeffect, which demonstrates typical dose-response relationship is of temporary nature. There are many descriptions of low energy laser irradiation curing various eye diseases. None of these claims is scientifically and medically substantiated and all low energy laser therapies must by considered experimental at best.
