    Author: Yang W, Hu S, Wang J.
    Journal: Zhonghua Yan Ke Za Zhi; 1997 Jul; 33(4):272-6. PubMed ID: 10451959.
    Abstract:
    OBJECTIVE: To study the characteristics of color Doppler imaging (CDI) of ocular tumors for the diagnosis and differential diagnosis of the tumors. METHODS: 92 cases with ocular tumor (105 eyes) were examined by CDI to observe the vasculature of ocular tumors, and the various parameters of blood vessels and blood flow in the lesions were measured. SAS software was used to analyze the results. RESULTS: Blood flow signal can be found in retinoblastoma, melanoma of choroid, angioma of choroid, angioma of optic nerve papilla, Coats disease, persistent hyperplastic primary vitreous (PHPV) and metastatic tumors of choroid, but we can not find any blood flow signal in choroid osteoma and melanocytoma of optic nerve papilla. The blood flow parameters of central retinal artery in choroidal melanoma and that of ophthalmic artery, central retinal artery and posterior ciliary artery in angioma of choroid are lower than normal (P < 0.05). In the comparison of the blood velocity in the posterior ciliary artery between choroidal melanoma and choroidal angioma, it was found that the former is much higher than the latter (P < 0.05). CONCLUSION: CDI is very important in the diagnosis and differential diagnosis of ocular tumors.
