Abstract:

Ruby laser flashes of 5-250 joules energy and 1 msec duration were focused by external optics into the eyes of seven monkeys, illuminating a retinal area of 78 sq mm. Temporary pitting of the corneal epithelium was seen at all energy levels, but cleared within 24 hours. Above 5 joules, the animals lens were destroyed as a result of the light being focused into the lens. The retina was gray, without a light reflex, and the central area often manifested acute hemorrhage. Peripheral vessels were blackened as were the central artery and vein. At energy levels above 10 joules, large gas bubbles present in the anterior chamber precluded further gross examination.
