| 摘 要： | 以３．５７Ｊ能量挫伤兔眼后，闪光视诱发电位（Ｆ－ＶＥＰ）峰时值延迟，振幅下降，至伤后１０周不能恢复正常。并致暗视视网膜电图（Ｄ－ＥＲＧ）ａ、ｂ波振幅下降，其中ｂ液下降明显，４周恢复。视网膜电图振荡电位（ＯＰｓ）的总和波幅下降程度不及ＥＲＧ严重。以上电生理改变均于伤后当时及３周明显。

| Abstract: | After 3.57 J power injury on rabbit eyes, the latent peak value in F-VEP defered and the amplitude declined following ocular contusion in rabbits, and did not recover to normal at the tenth post-traumatic week. The amplitude of a-waves and b-waves in D-ERG declined and recovered at the 4th week. The declined degree of OPs's total amplitude was less than ERG. The changes in electrophysiolohy were remarkable immediately after trauma and the 3th posttrau-matic week. |
