[Energy metabolism in structures of the visual analyzer and neurons of the sympathetic ganglion after irradiation of the eye with low-intensity infrared laser radiation in the near-spectrum region]. / Sostoianie énergeticheskogo obmena v strukturakh zritel'nogo analizatora i neironakh simpaticheskogo gangliia posle oblucheniia glaza nizkointensivnym infrakrasnym lazernym izlucheniem blizhnei oblasti spektra.

After irradiation of one eye by low-intensive infrared laser with near spectral region within 5 and 20 min an increase in aerobic oxidation (activation of glutamate- and succinate dehydrogenases, decrease in activity of lactate dehydrogenase and in content of lactate) as well as alterations in the antioxidant activity were observed in structures of both eyes (irradiated and untreated), in visual cortex of both hemispheres and in neurocytes of upper cervical sympathetic ganglions. These results suggest that generalized metabolic reactions are developed in a body in response to laser irradiation. Mechanism of these reactions appears to involve not only the neuro-reflex pathways but it related also to the direct effect of the radiation on structures of eye and brain. The low-intensive laser radiation penetrated into brain through eye retrobulbar tissues and bones.

It has been established in a study on animals and human cadavers that light can penetrate the brain through the intact skin and eyes. Quantitative optical characteristics of the brain and internal organs are presented.
