Low Level Infrared Irradiance Ocular Effects.
Abstract
The ocular lenses of checker rabbits were exposed to infrared radiation at 1064 nm. Exposures were made with a cw laser with exposure times varying up to 3000 seconds. Exposures were repeated at weekly intervals with power levels chosen such that no retinal lesions were produced. Documentation of retinal and lenticular effects was provided by fundus and slit lamp photography. Opacities were observed on the posterior poles of the rabbit lenses. Following the exposure sequences, the lenses were removed and the capsule, cortex and nucleus separated. The components were homogenized and subjected to polyacrylimide gel electrophoresis. In addition, measurements of intralenticular light scattering and posterior pole opacity size were made. However, the cortex of irradiated lenses contained more insoluble material than did the cortex of non-irradiated lenses. Opacity size and density may have been a function of both irradiation and anesthesia usage.
