Abstract : Maximal visual acuity and normal color vision are closely associated with foveal receptor function. When the fovea is destroyed or altered by intense laser light, severe and often permanent losses in visual sensitivity ensue. In this report we have shown that the threshold for long-term functional alterations is determined not only by the wavelength and corneal exposure power of the laser flash but also by the types of performance criteria used to assess visual sensitivity. Effects of minimal diameter spots were also examined in one subject exposed to Argon light.
