title: The a- and b-wave latencies as a prognostic indicator of neovascularisation in central retinal vein occlusion.
abstract: 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.
