Abstract
Considerable information is now available concerning chorioretinal burns produced by atomic flash.1-4 The purpose of the present research was to determine the threshold conditions for the production of such lesions and the course of healing in such a threshold burn. Since the ocular media transmit a relatively narrow spectral band, the source of energy used is not important, as long as its spectral emission covers the range from 0.3μ to 1.3μ (Fig. 1). However, since species may be an important factor and since human volunteers are not readily available, it was necessary to use several mammalian species in order to establish a basis for generalization to the human eye. Apparatus The light source used in this study was a U. S. Army searchlight, 24 in., Model 1942. The light from the carbon arc is focused by a reflector into a fairly intense beam with uniform flux-density within about 5 mm.
