ERG与视功能预后的关系进行探讨。方法　139例 14 6眼 RD患者检测其 ERG,通过散大瞳孔直视眼底监控固视状态 ,记录分析 a波、b波与振荡电位 ( oscillatorypotentials,OPs)各项成分。结果　与对照组相比 ,ERG的 a波、b波与 OPs波的异常率 :<1周组分别为 16 .0 0 %、16 .0 0 %、10 .0 0 % ;1～ 2周组为 35.0 0 %、4 5.0 0 %、50 .0 0 % ;2～ 4周组为 4 6 .80 %、 56 .2 5%、 6 2 .50 % ;4～ 8周为76 .0 0 %、 84 .0 0 %、 88.0 0 % ;8周以上组则为 86 .96 %、91.30 %、95.6 5% .a波与 b波在脱离时间 <1周组与对照组无明显差异 ;1～ 2周组 a波与 b波开始有明显降低 ( P<0 .0 5) ,随着发病时间的不断延长 ,b波的下降较 a波更为迅速 ,2～ 4周则具有显著意义 ( P<0 .0 1) ;b/ a值在早期 RD病变表现正常或轻度异常 ,伴随病程增加有降低趋势 ,4～ 8周即出现显著性降低 ( P<0 .0 5)。结论　 ERG对<em><Abstrcat>ObjectiveTo understand the sites and characteristics of macular dysfunction in retinal detachment (RD) by evaluating components of electroretinogram(ERG).MethodsERG was recorded in 146 eyes of 139 patients of retinal detachment by using a handheld stimulator with direct visualization of the funlus through dilated pupils.ResultsCompared to controls ,the patients showed losses of awave and bwave and oscillatory potentials(OPs) amplitudes .The abnormality ratios of awave and Dwave and OPs in RD affected time:<1week were 1600%,16.00% and 10.00%;1~2weeks were 35.00%,45.00% and 5000%;2~4weeks were 46.80%,56.25% and 62.50%;4~8 weeks were 76.00%,84.00% and 88.00%;>8weeks were 8696%,91.30% and 9565% respectively. On average ,bwave decreased quicker than awave ,and b/a tended to decrease with the course of disease .The results showed awave ,bwave and OPs decreased in the RD eyes with macular detachment (P<005).Conclusion ERG is an important indicator for prognosis of the functional recovery of the attached eye after corrective surgery.</em></p><p class='subject'><strong>关 键 词：</strong><a href='/zk/search.aspx?key=K%3d%5b%e8%a7%86%e7%bd%91%e8%86%9c%e8%84%b1%e7%a6%bb%5d' title='视网膜脱离'>视网膜脱离</a> <a href='/subject/article.aspx?id=2178152' target='_blank'><b class='type_ico_id'></b></a><a href='/zk/search.aspx?key=K%3d%5b%e8%a7%86%e7%bd%91%e8%86%9c%e7%94%b5%e6%b5%81%e5%9b%be%5d' title='视网膜电流图'>视网膜电流图</a> <a href='/subject/article.aspx?id=1415975' target='_blank'><b class='type_ico_id'></b></a><a href='/zk/search.aspx?key=K%3d%5b%e6%8c%af%e8%8d%a1%e7%94%b5%e4%bd%8d%5d' title='振荡电位'>振荡电位</a> <a href='/subject/article.aspx?id=2172458' target='_blank'><b class='type_ico_id'></b></a><a href='/zk/search.aspx?key=K%3d%5b%e8%a7%86%e8%a7%89%e9%9a%9c%e7%a2%8d%5d' title='视觉障碍'>视觉障碍</a> </p><p class='class'><strong>分 类 号：</strong><a href='/zk/search.aspx?key=C%3dR774.12' title='R774.12'>R774.12</a>[<a href = '/domain/article.aspx?id=507' >医药卫生—眼科</a>] </p> </div> <div id="content_wzxg" name="wzxg" class="article-graph"> <object width="695" height="250" classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" id="FlashID"> <param value="../flash/relation.swf" name="movie"> <param value="high" name="quality"> <param value="opaque" name="wmode"> <param value="6.0.65.0" name="swfversion"> <param value="dataUrl=/ajax/articlerelativegraph.ashx?id=6902506" name="flashVars"> <embed width="695" height="250" src="../flash/relation.swf" type="application/x-shockwave-flash" quality="high" wmode="opaque" flashvars="dataUrl=/ajax/articlerelativegraph.ashx?id=6902506"> </embed> </object> </div> <div class="article-relate-list"> <div class="relate-list"> <p id="ckwx_br"> </p> <h2 name="ckwx" id="ckwx">参考文献：</h2> <div id="listckwx"> <p class='submit'> <img src='/images/loading.gif' width='16' height='16' /> 正在载入数据... </p> </div> </div> <div class="relate-list"> <p id="2jckwx_br"> </p> <h2 name="2jckwx" id="2jckwx">二级参考文献：</h2> <div id="list2jckwx"> <p class='submit'> <img src='/images/loading.gif' width='16' height='16' /> 正在载入数据... </p> </div> </div> <div class="relate-list"> <p id="ohwx_br"> </p> <h2 name="ohwx" id="ohwx">耦合文献：</h2> <div id="listohwx"> <p class='submit'> <img src='/images/loading.gif' width='16' height='16' /> 正在载入数据... </p> </div> </div> <div class="relate-list"> <p id="yzwx_br"> </p> <h2 name="yzwx" id="yzwx">引证文献：</h2> <div id="listyzwx"> <p class='submit'> <img src='/images/loading.gif' width='16' height='16' /> 正在载入数据... </p> </div> </div> <div class="relate-list"> <p id="2jyzwx_br"> </p> <h2 name="2jyzwx" id="2jyzwx">二级引证文献：</h2> <div id="list2jyzwx"> <p class='submit'> <img src='/images/loading.gif' width='16' height='16' /> 正在载入数据... </p> </div> </div> <div class="relate-list"> <p id="tbywx_br"> </p> <h2 name="tbywx" id="tbywx">同被引文献：</h2> <div id="listtbywx"> <p class='submit'> <img src='/images/loading.gif' width='16' height='16' /> 正在载入数据... </p> </div> </div> <div class="relate-list"> <p id="xgqklw_br"> </p> <h2 name="xgqklw" id="xgqklw">相关期刊文献：</h2> <div id="listxgqklw"> <p class='submit'> <img src='/images/loading.gif' width='16' height='16' /> 正在载入数据... </p> </div> </div> </div> </div> <div class="article-about"> <div class="about-box"> <h5 class="name">相关的主题<tt><a class="hide" href="#"></a></tt></h5> <div class="about-list"> </div> </div> <div class="about-box"> <h5 class="name">相关的作者对象<tt><a class="" href="#"></a></tt></h5> <div class="about-list" style="display: none;"> </div> </div> <div class="about-box"> <h5 class="name">相关的机构对象<tt><a class="" href="#"></a></tt></h5> <div class="about-list" style="display: none;"> </div> </div> </div> </div> </div> <script type="text/javascript" src="/scripts/articlerelation.min.js"></script> <script type="text/javascript" src="/scripts/articlerightrelation.min.js"></script> <script type="text/javascript" src="/scripts/articledown.min.js"></script> <div class="layer-box download" id="downloadlayer" style="display: none"> <div class="close"> <a onclick="closedown()" href="javascript:void(0)"> <img src="/images/layer-close.png" width="21" height="21" alt="" /> </a> </div> <h5 class="layer-title">下载全文</h5> <div id="downloadinfo"></div> </div> <div class="layer-box download" id="downloadlayer2" style="display:none;min-height:100px;width:500px;"> <p> <img src="/images/loading2.gif" width="64" height="64"> <span style="font-size:20px;vertical-align:middle;padding-bottom:50px;">正在链接到云南高校图书馆文献保障联盟下载...</span> </p> </div> <script id="bdshare_js" data="type=tools&uid=0" type="text/javascript"></script> <script type="text/javascript"> $(function () { var rd = GetQueryString("rd");
