To evaluate the value of color Doppler ultrasonography (CDU) in the diagnosis of intraocular lesions.
82 cases of intraocular diseases were examined by high-resolution CDU (7.5 mHz), and the blood flow pattern was evaluated at the base of two-dimensional image.
CDU might show the blood flow of retinal vessels in all 21 cases of retinal detachment, no blood flow could be detected in 21 of 22 vitreous hemorrhages and/or membranes, and only in one case with diabetic proliferative retinopathy did fine blood flow be seen. Intratumor blood flow with branchy pattern could be detected in 17 of 18 cases with choroidal melanomas and 3 of 4 cases with choroidal metastatic carcinoma, and spectral analysis revealed high-resistance, simulating arterial blood flow waves. In 5 cases with choroidal hemangioma, intratumor blood flow with filled or sparkled pattern was detected, and the spectral analysis revealed both arterial and venous blood flow waves. No blood flow in the lesion was detected in simulating benign lesions i.e. 5 choroidal hemorrhages and 2 subretinal hemorrhages. In 3 cases (4 eyes) with persistent hyperplastic primary vitreous (PHPV), CDU showed band-shaped arterial blood flow coursing from optic nerve disc to the posterior surface of the lens in the vitreous cavity.
CDU is helpful in the differential diagnosis among retinal detachment, vitreous hemorrhage, vitreous membrane, malignant choroidal melanoma, choroidal metastatic tumor, choroidal benign lesion or hemangioma, PHPV and lesions with white pupil.
评估彩色多普勒超声（CDU）在眼内病变诊断中的价值。
采用高分辨率CDU（7.5兆赫兹）对82例眼内疾病患者进行检查，并在二维图像基础上评估血流情况。
21例视网膜脱离患者中CDU均可显示视网膜血管血流；22例玻璃体积血和/或膜性病变中21例未检测到血流，仅1例糖尿病增殖性视网膜病变患者可见少量血流。18例脉络膜黑色素瘤患者中有17例、4例脉络膜转移癌患者中有3例可检测到肿瘤内呈分支状血流，频谱分析显示为高阻力，类似动脉血流波形。5例脉络膜血管瘤患者中，肿瘤内血流呈充盈或闪烁状，频谱分析显示既有动脉血流波形又有静脉血流波形。模拟良性病变即5例脉络膜出血和2例视网膜下出血病变内未检测到血流。3例（4只眼）永存原始玻璃体增生症（PHPV）患者中，CDU显示玻璃体内有条带状动脉血流从视盘流向晶状体后表面。
CDU有助于视网膜脱离、玻璃体积血、玻璃体膜、脉络膜恶性黑色素瘤、脉络膜转移瘤、脉络膜良性病变或血管瘤、PHPV及白瞳症病变之间的鉴别诊断。
