Since laser radiation consists of essentially parallel rays, the wavelengths to which the ocular media is relatively transparent are focused by the eye at or near the fundus, greatly concentrating the energy in the process. Because retinal damage can result, the differential effects in terms of wavelength and power levels is of considerable importance. In this study damage to the rabbit retina was induced by irradiation with neodymium, ruby, and frequency-doubled neodymium lasers. The neodymium laser wavelength 10,600 angstroms produced the smallest lesions and least damage. The ruby 6943 A and frequency-doubled neodymium 5300 A lasers caused lesions similar in size and seven day post-irradiation histo-pathology, except for inter-layer adhesion differences.
