[An experimental study of ocular contusion in rabbits: the changes in electroretinography].
In rabbits, the amplitude of a-waves and b-waves in the ERG declined following ocular contusion; however, the oscillatory potentials did not change markedly. In the anisodine therapeutic group, the amplitude of a-waves recovered higher than did that in the control group at the 2nd and 4th week post-traumatic, while all a-waves recovered at the 6th week in both groups. The amplitude of b-waves was restored to normal in 72 hours for all eyes. Since the a-wave was sensitive to contusion, it monitored the severity of damage and objectively evaluated the therapeutic effect of treatment.
