Effects of Coherent and Incoherent Light on Ocular Tissues and Visual Function in Non-Human Subjects, Annual Progress Report for October 1, 1980-September 30, 1981

摘要

One micron and thin sections from additional blocks of tissue from both eyes of animal N-403 & N-239 were submitted to this contractor for sectioning and interpretation. These showed no artefact-free evidence of the effects of coherent light upon the retinas nor were ultrastructural differences detected between the treated and untreated eyes (for further details see pages 1, 2, & 3 of report 1 dated Oct. 1980). Blocks of retina tissue were submitted to the contractor from both eyes of animal LA-1. Designation of which eye was exposed to coherent light and which eye was not, was withheld from the contractor until the contractor completed sectioning and interpretation of the submitted tissue. The animal did not show electrophysiological evidence of diminished spectral sensitivity in the treated eye. Fixation and embedding artefact was less than in blocks obtained from animals N-403 and N-239. No ultrastructural evidence of tissue alteration attributable to coherent light was found and no differences were detected between sections prepared from comparable areas of each retina.
