目的观察视网膜分支静脉阻塞(BRVO)后不同象限视盘周围1个视盘直径范围内,视盘与静脉阻塞部位之间视网膜近端血管直径的变化.方法参阅数字眼底彩色图片和荧光素眼底血管造影图片,对48例典型单侧BRVO患者静脉阻塞的部位进行定位,利用IMAGEnet软件对造影图片进行恒定的放大和对比度调整,由专人利用软件中线性测量工具对患眼和对侧健眼4个象限近端视网膜动脉和静脉血管直径进行测量,进行配对比较观察.结果患眼正常象限与健眼对应象限之间视网膜动静脉直径之间比较,差异没有统计学意义,但病变象限与对侧健眼对应象限视网膜动静脉直径之间比较,颞上或颞下阻塞象限的视网膜动脉直径均显著增加(t颞上=-2.342,P颞上=0.026;t颞下=-3.069,P颞下=0.010),而静脉直径则没有变化.结论 BRVO眼血管阻塞相应象限视网膜近端动脉直径显著增加,静脉直径无改变.

Objective To study the proximal diameter changes of retinal blood vessel following branch retinal vein occlusion (BRVO). Methods Color fundus photographs and fundus fluorescein angiography (FFA) photographs of 48 patients with typical unilateral BRVO were analyzed using IMAGEnet software.The diameter of retinal artery (RAD) and vein (RVD) close to optic disc (within one DD from the optic disc) in four quadrants including the affected quadrant were measured with linear measuring tools. Results The proximal diameter of RAD and RVD in corresponding normal quadrants of the BRVO eye had no significant change comparing with the contralateral eye. The proximal diameter of RAD, but not RVD of the affected quadrant such as superotemporal (t= -2. 342, P=0. 026) or inferotemporal (t= - 3. 069, P=0. 010) quadrant, increased remarkably. Conclusions In corresponding affected quadrant with BRVO, only RAD close to optic disc increases markedly, RVD has no significant change.
