The B-mode images of 32 patients affected with a malignant melanoma of the choroid were studied, in particular with respect to choroidal excavation. The degree of visibility of choroidal excavation at the B-scan was compared with the thickness of the choroid, scleral invasion, vascularisation, retinal detachment and the reflectivity of the tumour. None of these histological and echographical features appeared to be significantly related to the degree of the visibility of choroidal excavation. Also the condition of the choroid was studied. At examination of all the histological sections no choroid was found between tumour and sclera. This implies that choroidal excavation should be visible at echograms in every case instead of only in 75% of the cases as was found for our series.
对32例脉络膜恶性黑色素瘤患者的B超图像进行了研究，尤其关注脉络膜凹陷情况。将B超扫描时脉络膜凹陷的可见程度与脉络膜厚度、巩膜浸润、血管形成、视网膜脱离及肿瘤的反射率进行了比较。这些组织学和超声特征似乎均与脉络膜凹陷的可见程度无显著相关性。还对脉络膜的状况进行了研究。在检查所有组织切片时，未发现肿瘤与巩膜之间存在脉络膜。这意味着在超声图上，脉络膜凹陷在每种情况下都应可见，而不是像我们的系列研究中那样仅在75%的病例中可见。
