To evaluate the prognostic value of ERG in cases of central retinal vein occlusion (CRVO) regarding the development of neovascularisation (NV), we studied 20 patients with unilateral CRVO. Half of them were allocated in the perfused group and the other 10 finally developed NV and were allocated in the non-perfused group. Flash ERG was recorded from all patients. Our findings suggest that b-wave latency is the most reliable parameter in predicting NV, followed by the a-wave latency. The b/a wave amplitude of ERG ratio does not seem to be suitable for clinical use.
为评估视网膜电图（ERG）在视网膜中央静脉阻塞（CRVO）患者中对新生血管形成（NV）发展的预后价值，我们研究了20例单侧CRVO患者。其中一半被分配到灌注组，另外10例最终出现NV并被分配到非灌注组。对所有患者进行了闪光ERG记录。我们的研究结果表明，b波潜伏期是预测NV最可靠的参数，其次是a波潜伏期。ERG的b/a波幅比值似乎不适用于临床。
