| 摘 要： | 我们选择不同的刺激条件，对32例早期视网膜中央静脉阻塞(central retinal vein occlusion,CRVO)患者进行视网膜电图(electroretinogram,ERG)的检测．缺血型CRVO13例的a、b波潜伏期延长，b波振幅明显下降：非缺血型CRVO19例的a、b波潜伏期延长，b波振幅表现为轻度降低、升高或正常．提示b波振幅和b/a是区分缺血型与非缺血型CRVO的最敏感指标．我们还探讨了ERG在早期CRVO分型中的应用价值。（中华眼底病杂志，1994，10：7-10） |

| Abstract: | By using the different light stimuli, the flash ERG of 32 cases of central retinal vein occlusion(CRVO) (13 of ischemic type,19 of non-ischemic type) during acute phase were examined. The results showed that the a-wave and b-wave latency of CRVO elongated,while the b-wave amplitude of ischemie type decreased and that of non-ischemic type varied in different stimulus: decreased,increased or normal.Therefore,b-wave amplitude and b/a ratio,and selection of suitable ERG condition of stimulus are thought to be important in differetiating ischemic from non-ischemic CRVO.(Chin J Ocul Fundus Dis,1994,10:7-10） |
