| 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（ｃｅｎｔｒａｌｒｅｔｉｎａｌｖｅｉｎｏｃｃｌｕｓｉｏｎ，ＶＲＶＯ）患者进行视网膜电图（ｅｌｅｃｔｒｏｒｅｔｉｎｏｇｒａｍ，ＥＲＧ）的检测。缺血型ＣＲＶＯｌ３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值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。 |

| Abstract: | By using the different light stimulus , 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,Theresults showed that the a-wave and b-wave latency of CRVO elongated, while the b-wave amplitudeof ischemlc 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 ERGcondition of stimulus are thought to be important in differentiating ischemic from non-ischemicCRVO. |
