目的观察5期早产儿视网膜病变的超声显像特征.方法用彩色多普勒超声诊断仪检查80例(150只眼)于眼科临床检查发现异常的早产患儿,并观察彩色多普勒血流成像(CDFI)形态特点及病变的血流特征.结果在早产儿患眼超声检查80例(150只眼)眼内显示为与晶状体回声紧密相连并包绕其周围的不规则光团回声,光团与视乳头间条索状光带相连,血流特点表现为条索状光带上显示与视网膜中央血管相延续的血流信号,脉冲多普勒显示沙堆状动脉血流频谱特征.结论彩色多普勒超声能清晰显示5期早产儿视网膜病变的超声显像特征和血流特征,结合临床病史,为诊断提供重要的依据.

Objective To observe ultrasound characteristics in stage Ⅴ retinopathy of prematurity.Methods All 80 patients (150 eyes) with retinopathy of prematurity were examined with color Doppler flow imaging (CDFI). The morphologic characteristics of color Doppler flow imaging and blood stream were observed in patients with retinopathy of prematurity. Results Among 150 eyes with retinopathy of prernaturity at stage Ⅴ, there were 80 patients in whom we observed that lump-like echo connected closely with echo of lens and the circumambience was surrounded and the zonal echo was attached to the optic disc. The features of blood flow showed the signal of blood stream connected with central retinal vessels, which was analyzed by Doppler spectrum as the blood-flow spectrum like sand-heap. Conclusions The morphologic changes of color Doppler flow imaging and the features of blood flow are useful in diagnosis of retinopathy of prematurity patients at the stageⅤ.
