Color Doppler imaging diagnosis of intra-ocular tumor
Objective:
To demonstrate the color Doppler imaging (CDI) of intra-ocular tumors and its importance in the diagnosis of these tumors.
Methods:
Ninety-two patients with intra-ocular tumors (105 eyes) were examined by using CDI to observe the vasculature of these tumors, and using SAS soft ware to analyze the results.
Results:
Blood flow signal was found in retinoblastoma, melanoma of choroid, angioma of choroid, angioma of optic disc, Coats' disease, persistent hyperplastic primary vitreous (PHPV) and metastatic tumors of choroid, but not found in choroid osteoma and melanocytoma of optic disc. The blood flow decreases in central retinal artery in choroidal melanoma and also in ophthalmic artery, central retinal artery and posterior ciliary artery in angioma of choroid (P < 0.01). It was found that blood velocity is much faster in choroidal melanoma than in choroidal angioma (P < 0.05).
Conclusions:
CDI is very important and helpful in the diagnosis of intra-ocular tumors.
