简介:血管生成素(angiopoietin,Ang)是特异性作用于血管内皮细胞的生长因子,主要由Ang-1和Ang-2组成;Tie2(tyrosinekinasethatcontainsimmunoglubin-likeloopsandepidernalgrowthfactor-similardomains2)是其共同受体.Ang-1促使血管成熟,维持血管稳定.Ang-2则拮抗Ang-1的作用,始动病理性新生血管形成.在眼部新生血管形成过程中Ang/Tie2受体途径起重要作用,抑制Ang/Tie2受体途径可以抑制眼部新生血管形成.
简介:患者,男,51岁,2004年8月因“左眼颈椎手术后视物不见2个月”至本院就诊。左眼:视力无光感,眼球各方向运动中度受限,屈光介质透明,瞳孔散大,直接对光(-),间接对光反应迟钝,视网膜灰黄色,血管变细,视乳头苍白,脉络膜背景污秽色,眼底无出血渗出。右眼:无阳性体征。现病史:患者2004年6月因“无骨折脱位性颈脊髓损伤并不全瘫”在当地医院行颈椎手术。麻醉方式:静脉复合麻醉,俯卧,颈部过伸位。手术持续时间:4小时40分。术前患者双眼视力均正常,苏醒后即左眼视物完全不见,右眼正常,当地医院眼科检查治疗情况不详。我院诊断:左眼部缺血综合征。
