Effect of X-radiation on the morphogenesis and histogenesis of the developing retina of the chick embryo

Morphological and histological studies were done on the retina of 10, 12 and 15 days chick embryos which were exposed to X-irradiation [1000 R at 200 k.v.] 48 hours after incubation. Retardation of growth of the retina was observed in 10 and 12 days treated chick embryos as evidenced by reduction of the size of the retina associated with disappearance of some layers of the retina. The retina of irradiated embryos showed signs of incomplete regeneration when these embryos were examined on the 15th day of incubation
