彩色多普勒血流显像和多普勒能量图诊断脉络膜脱离的价值

目的 探讨彩色多普勒血流显像(CDFI)和多普勒能量图(CDPI)诊断脉络膜脱离的价值。方法 用彩色多普勒超声对30例脉络膜脱离患者进行检查，在超声检查眼球形态、晶状体、玻璃体及视网膜的基础上，对眼内带状回声行CDFI和CDPI检查，了解其血流情况，并与手术结果对照。结果 30例脉络膜脱离患者，超声诊断符合率为80．0％，超声联合CDFI和CDPI诊断符合率上升为96．7％。脉络膜脱离的CDFI和CDPI声像图特点为血流丰富，血流束呈长条带状或短棒状。4例视网膜脱离3例见血流信号，但不丰富，血流束呈星点状。合并玻璃体积血14例，玻璃体混浊8例及玻璃体增殖机化4例。27例脉络膜脱离超声诊断与临床手术符合。结论 超声联合CDFI和CDPI检查可为脉络膜脱离的诊断和治疗提供有价值的参考。

Value of color Doppler flow imaging and Doppler power imaging in diagnosis of choroidal detachment

Objective To investigate value of color Doppler flow imaging(CDFI) and Doppler power imaging(CDPI) in the diagnosis of choroidal detachment(CD). Methods Color Doppler ultrasound was performed in 30 cases with choroidal detachment. At the base of eyeball shape, lens, vitreous and retina examined by ultrasound, intraocular band-shaped echo was examined by CDFI and CDPI, to understand its blood flow. The observation was compared with that of surgical results. Results Of 30 cases with choroidal detachment, the diagnostic positive correspondonce of ultrasound was 80.0%, while ultrasound combined with CDFI and CDPI, the correspondence increased up to 96.7%. The sonographic features of CDFI and CDPI in choroidal detachment patients were abundant blood flow in band-shape or short stick-like. In 3 cases out of 4 cases with retinal detachment, blood flow was not abundant,their blood flow showed a sparked pattern. In addition, 14 cases combined with vitreous hemorrhage, 8 cases had vitreous opacity and 4 cases vitreous proliferation. Ultrasound diagnosis corresponded with that of clinical surgery in 27 choroidal detachment cases. Conclusions Ultrasound combined with CDFI and CDPI provide valuable references for diagnosis and treatment of choroidal detachment.
