Experimental modeling of oxidative stress was conducted by creating circulatory brain hypoxia, accompanied by development of free radical processes leading to genome instability through an example of anterior epithelial layer of rat cornea. We studied the influence of infrared low-level laser radiation (ILLLR) in the therapeutic dose and mode (pulse power 8 W, λ=0.89 μm). Exposure of animals with circulatory brain hypoxia (ischemia) to ILLLR reduced the level of chromosome aberrations in corneal epitheliocytes and led to change in the mitotic index. Correction of the damaging effects of ischemia in the experiment in the absence of mutagenic effect of ILLLR in therapeutic dose and mode of exposure indicates the possibility of applying this physical method for correcting after-effects of oxidative stress during progression of degenerative eye diseases in ophthalmic practice.
