目的:评价高频彩色多普勒超声(color doppler flow imaging，CDFI)在辅助玻璃体积血（vitreous hemorrhage, VH）术前病因诊断中的应用价值。 方法:对20例20眼二维超声图像上表现VH的患眼，通过CDFI和眼底及既往病史进行术前诊断。所有患者均行玻璃体切割手术，结合术中所见和术后荧光素血管造影、吲哚青绿造影进行术后诊断。 结果：VH患眼20例20眼CDFI检出视网膜脱离5例（25%），视网膜脱离合并脉络膜脱离2眼（10%）,视网膜下出血2眼（10%）。经手术证实,增殖性糖尿病视网膜病变7例（35%），视网膜中央/分支静脉阻塞7例（35%），孔源性视网膜脱离3例（15%），年龄相关性黄斑变性1例（5%），息肉样脉络膜视网膜病变1例（5%），Eales病1例（5%）。术前诊断和术后诊断符合率为95%(19/20)。 结论：高频CDFI可辅助VH术前病因判断,并有效地指导临床治疗。

AIM: To evaluate application value of high-frequency color doppler flow imaging (CDFI) on the pre-operative diagnosis of vitreous hemorrhage. METHODS:High-frequency CDFI was performed on 20 patients (20 eyes) with vitreous hemorrhage(VH). Pre-operative diagnosis was given by CDFI, fundus examination and previous history. All patients were performed vitrectomy. Post-operative diagnosis was based on observation during operation, post-operative fluorenscense angiography and indocaine angiography.  RESULTS:In these 20 eyes with VH, there were 5 eyes (25%) with retinal detachment, 2 eyes (10% ) with retinal detachment and choroidal detachment, and 2 eyes (10%) with subretinal hemorrhage. It was evidenced by operation that there were 7 cases (35%) with proliferative diabetic retinopathy, 7 cases (35%) with central or branch retinal vein occlussion, 3 cases (15%) with rhegmatogenous retinal detachment, 1 cases (5%) with age-related macular degeneration, 1 case (5%) with polypoid chorioretinopathy, and 1 case (5%) with Eales disease. The CDFI results of 19 eyes among 20 eyes (95%) were consistent with the observation in surgical operation.  CONCLUSION:High-frequency CDFI can contribute to preoperative judgment for the cause of VH, and to effectively guide clinical treatment.
