Vitreous haemorrhage is an unusual presenting feature of malignant melanoma of the choroid. We describe three cases in which this occurred. The three tumours shared a number of common features: all were located in the peripheral choroid, were of a similar size and had a small herniation of tumour tissue through Bruch's membrane. We believe that vascular congestion caused by constriction of the tumour vasculature at the site of herniation is the most probable cause for the haemorrhage in these cases. We review the relevant literature and discuss some of the commoner differential diagnoses.
玻璃体积血是脉络膜恶性黑色素瘤一种不常见的临床表现。我们描述了三例出现这种情况的病例。这三个肿瘤有一些共同特征：均位于周边脉络膜，大小相似，且有肿瘤组织通过布鲁赫膜形成小的疝出。我们认为，疝出部位肿瘤血管收缩导致的血管充血是这些病例出血最可能的原因。我们回顾了相关文献并讨论了一些较常见的鉴别诊断。
