摘要
目的观察早产儿视网膜病变(ROP)的彩色多普勒血流成像(CDFI)检查的形态特点和血流特征,为ROP临床诊断提供新的依据。方法对78例有典型早产、出生体重低等病史并经散瞳双目间接检眼镜眼底检查确诊的4、5期ROP患儿的156只患眼进行CDFI检查,观察其CDFI形态特点及病变的血流特征。结果4期病例主要表现为玻璃体内有起自一侧周边眼球壁的弱条带状回声,向后极部与眼球壁回声相延续并与视盘回声相连;5期病例主要表现为与晶状体回声紧密相连并包绕其周围的团状回声,合并视网膜脱离时病变类似荷花状,前段膨大的“花体”包绕晶状体并与其紧密相连,向后逐渐变细为“茎部”,呈弱条带状回声与视盘相连。血流特点表现为病变的“茎部”可见与视网膜中央动静脉相延续的血流信号,脉冲多普勒频谱分析为动脉静脉伴行的血流频谱,与视网膜中央动脉静脉完全相同。结论4、5期ROP患儿CDFI主要表现为玻璃体内带状或团状回声,其中可见与视网膜中央动静脉相延续的血流信号。根据CDFI形态改变和血流特征有助于ROP的诊断。
Objective To observe the morphologic characteristics of color Doppler flow imaging （CDFI） and blood stream in patients with retinopathy of prematurity, and provide the new clinical diagnostic gist. Methods CDFI was performed on 78 patients （156 eyes） with ROP at Ⅳ and Ⅴ stage, who had the diseases history such as prematurity and low birth-weight which had been diagnosed by indirect ophthalmoscope, underwent the examination of CDFI. Morphologic characteristics of the results of CDFI and features of blood flow of the pathological changes were observed. Results In the patients with ROP at the IV stage, a weak zonal echo originated from one side of peripheral wall of eye ball in the vitreous body, and extended to the echo of post pole and wall of eye ball and joined the echo of optic disc. In the patients with ROP at the Ⅴ stage, lump-like echo connected closely with echo of lens and the circumambience was surrounded; the focus looked like lotus when combined with retinal detachment： the swelled “corona” wrapped and tightly connected with the lens, and the thin “caulis” showed weak zonal echo which attached to the optic disc. The features of blood flow showed the signal of blood stream connected with central retinal artery at the “caulis”, which was analyzed by Doppler spectrum as the blood-flow spectrum of artery and vein in the same direction which was the same as the central retinal artery and vein. Conclusions In patients with ROP at the IV and V stage, the results of CDFI mainly shows zonal or lump-like echo, in which the blood-flow signal extended with central retinal artery could be seen. The morphological changes of CDFI and the features of blood flow are useful in diagnosis of ROP.
