    Forty-five out of 45 retinoblastoma patients studied with high resolution computed tomography at the Hospital For Sick Children, Toronto, Canada, showed evidence of intraocular calcification. Simulating lesions such as Coat's disease, persistent hyperplastic primary vitreous (PHPV), toxocara, dominant exudative vitreal retinopathy (DEVR) and choroidal juvenile xanthogranuloma failed to demonstrate any calcifications. Thus in young patients in whom retinoblastoma is suspected, the presence of calcification on CT scan is diagnostic of retinoblastoma;
    在加拿大多伦多儿童病院,用高分辨力CT研究了45例视网膜母细胞瘤病人,均显示有眼内钙化的表现,而其他相类似的病变,如Coats病,永存性初发玻璃体增生症(PHPV),弓蛔虫病,显性渗出性玻璃体视网膜病变(DEVR)以及青少年性脉络膜黄色肉芽肿等,没有看到任何钙化的征象,故此,年幼病人疑为视网膜母细胞瘤时,CT检查如能显示钙化,则可作出诊断,否则,可能是其他相类似的病变。
    In 3 cases (4 eyes) with persistent hyperplastic primary vitreous (PHPV), CDU showed bandshaped arterial blood flow coursing from optic nerve disc to the posterior surface of the lens in the vitreous cavity.
    在3例(4只眼)永存性原始玻璃体增殖症中,玻璃体腔内可见呈条索状由视乳头向晶体后延伸的动脉血管血流。
    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.
    结果视网膜母细胞瘤、脉络膜黑色素瘤、脉络膜血管瘤、视盘血管瘤、脉络膜转移癌,Coats病及原始玻璃体增生症(persistenthyperplasticpri-maryvitreous,PHPV)的病变上均可发现血流信号; 而脉络膜骨瘤和视乳头黑色素细胞瘤的病变内无血流信号。

    结论 :对于裂孔大小、形态、数量、分布、位置稍特殊或屈光介质混浊影响眼底检查等未伴明显PVR的较复杂型裂孔性视网膜脱离 ,首选不联合巩膜扣带的玻璃体手术 ,有利于提高一次性手术复位率和视功能恢复 ,并减少并发症。
