Abstract : Small foveal lesions produced by single, Q-switched (532 nm) pulses were difficult to detect both morphologically and behaviorally. These lesions were produced by pulses significantly above the ED 50 and their effects changed over time as perhaps edema and repair mechanisms proceeded. The initial deficits in visual functions were often slight and variable. As additional pulses were presented, the variability decreased while the visual deficit increased. Computer analyses of funds changes in grey scale taken from exposed retinae also change over time and correspond to our behavioral data. Keywords: Laser damage; Ocular hazards; Foveal acuity Losses; Q-switched laser pulses; Rhesus monkeys; Minimal diameter spot; Fundoscopic changes; Retinal lesions; Light induced damage; MPE; ND:YAG.
