Rabbit corneas were irradiated with larger doses of beta rays than the minimum prescribed in the use of Dedermann's ophthalmic Sr/sup 9//sup 0/ applicator SAI type 3. After an incubation period, inflammatory opacity and edema of the corneas were observed, followed by vascularization, vesicle forma- . tion, ulceration, necrosis, and perforation. With irradiation of not more than 54000 r for 360 min, the opacity was absorbed leaving a slight corneal scar, but with irradiation of over 36000 r for 420 min, severe damage, including perforation, occurred in the majority of cases. Individual differences were observed in sensitivity to beta rays, even in normal corneas. No abnormality of the lens was observed. At the same time as, or before, the appearance of keratitis, various signs of inflammation were present in the iris and conjunctiva. In an extreme case, hemorrhage was observed, but it disappeared as time progressed. (Abstr. Japan Med., 1: No. 8, 1961)
