COLOR DOPPLER IMAGING DIAGNOSIS OF INTRAOCULAR TUMOR

Objective To demonstrate the color Doppler imaging (CDI) of intra-ocul ar tumors and its importance in the diagnosis of these rumors. Methods Ninety-two patients with intra-ocular tumors (105 eyes) were examined by using CDI to observe the vascula ture of these tumors, and using S AS soft ware to analyze the results. Results Blood flow signal was fou nd in retinoblastoma, melanoma of choroid, angioma of choroid, angioma of optic disc, Coats' disease, persistent hyperplastic primary citreo us (PHPV) and metastatic tumors of choroid, but not found in choroid o steoma and melanocytoma of optic disc. The blood flow decreases in cen tral retinal artery in choroidal melanoma and also in ophthalmic arter y, central retinal artery and posterior ciliary artery in angioma of c horoid (P < 0.01). It was found that blood velocity is much faster in choroidal melanoma than in choroidal angioma (P < 0.05). Conclusions C DI is very important and helpful in the diagnosis of intra-ocular tumo rs.
