Résumé
Objective To evaluate color Doppler ultrasonography(CDU) in the diagnosis of intraocular tumor. Methods Two hundred seventy-three cases(301 eye) of intraocular space-occupying lesions were examinated by high-resolution CDU to observe the two-dimensional gray-scale image and vasculature of intraocular tumors. Results Intratumor calcifying spot could be detected in 138 cases(149 eye) of 153 cases(178 eye) with retinoblastoma,and intratumor blood flow with branchy pattern could be found in 152(177 eye) of 153 cases(178 eye) with retinoblastoma. In 4 Coats disease and 2 persistent hyperplastic primary vitreous and 3 retinopathy of prematurity, intratumor calcifying spot couldn′t be detected,and the band blood flow of the detached retinal vessels could be detected. Intratumor blood flow with branchy pattern could be detected in all 66 choroidal melanomas and 4 melanomas of ciliary body with infiltrated choroid and 15 of 19 choroidal metastases. Intratumor blood flow with “simulating vessel pool” or conglomerate sparkled pattern could be found in 12 choroidal hemangioma. No intrinsic flow was detected in 8 choroidal hemorrhages or subretinal hemorrhages and 2 teratoid medulloepitheliomas. Conclusions CDU is of significance in the diagnosis and differention of intraocular tumors.
