Seven Cynomolgus Fasciculata who had graded laser lesions placed in one eye only 6 years previously were evaluated by electro-physiological recording techniques. All animal recordings were performed under IACUC approved protocols. The single q-switched pulses from a neodymium-YAG laser produced lesions of 4 types at the time of placement no visible change, minimal visible lesions, white dot lesions localized circumscribed retinal blanching and red dot lesions contained retinal hemorrhage. Single exposures had been made both foveally and at 5 degrees eccentricity in the parafovea superiorly, inferiorly and temporally. The multifocal perimetric electiroretinogram was recorded from specialized contact lenses through hospital grade amplifiers.
