[The morphogenesis of the retinal neural layer and of the optic nerve in the normal white rat and under the action of large doses of x-ray irradiation during prenatal ontogeny].

Development of retina nerve layer and optic nerve were studied in 50 embryos and fetuses of albino rat in normal embryogenesis and in 55 embryos affected by large doses of X-ray irradiation (2.24 Cy) on d 10-14 of pregnancy (second critical period-a period of placentation and organogenesis). Main regularities in the development of the structures studied were demonstrated in intact fetuses. In the experiment the progeny subjected to X-ray irradiation showed basically bilateral abnormalities in development of retina nerve layer, optic nerve and its coats.
