Methods Twenty-eight patients(53 eyes)with high myopia and 32 cases with emmetropia(64 eyes)in control group were examined by GE lightspeed pro 16-slice spiral CT. The perfusion image and the blood volume(BV)of the posterior equatorial eye-ring were obtained and analyzed.
方法对我院28例53只高度近视眼和32例64只正视眼,采用GE Lightspeed pro 16层螺旋CT机进行CT灌注扫描,获取眼球赤道后眼环血容量值(BV),建立数据库并进行分析。
