Abstract : The ERG of the mangabey was found to be altered by a single laser pulse of low energy density (0.2 J/cm2) which irradiated a large retinal area. ERG's recorded 6 or more days post-exposure showed a depression or absence of the third oscillatory potential. The implicit time of the b wave was significantly shorter (p <. 001) post-exposure. Replication of the study with testing at 6-10 days and 6 months post-exposure revealed statistically significant post-exposure ERG changes persisting up to 6 months. (Author)
