The electroretinogram (ERG) vs perfusion pressure relation was studied in anesthetized rabbits during mechanically induced changes in mean arterial pressure (MAP). After 1 hr of dark adaptation, ERGs were obtained at perfusion pressures from 10 to 95 mmHg with each pressure held for 30-60 sec, and at three levels from 15 to 75 mmHg with each pressure held for 5 min. The slopes of the b-wave amplitude vs perfusion pressure data were not significantly different from zero during either the brief or longer manipulations of perfusion pressure. However, the b-wave was nearly extinguished 5 min after death. The results indicate that the rabbit ERG is maintained over a wide range of perfusion pressure.
