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.
在家兔中，眼挫伤后视网膜电图（ERG）的a波和b波振幅下降；然而，振荡电位没有明显变化。在山莨菪碱治疗组中，创伤后第2周和第4周时，a波振幅恢复得高于对照组，而两组在第6周时所有a波均恢复。所有眼睛的b波振幅在72小时内恢复正常。由于a波对挫伤敏感，它可监测损伤的严重程度并客观评估治疗效果。
