The retinas of pigmented, grey chinchilla rabbits were exposed to the visible, and, to the visible and near infrared parts of the spectrum to determine the retinal burn threshold. The study included the variation of four primary parameters: the rate of delivery of energy, the retinal image size, the exposure time, and the spectral characteristics of the source. Analysis of the data indicated the following: for a given irradiance, the dose necessary to produce a threshold burn increased with the size of the retinal image, for equal total irradiance a higher dose was necessary when the near infrared was included in the spectrum than when the visible alone was present, and for a given retinal image, the threshold dose is determined as a function of the irradiance.
