We describe a case of iris microhaemangiomas (iris vascular tufts) causing spontaneous hyphaema and where examination showed that the patient also had idiopathic juxtafoveolar retinal telangiectasis. A systematic search through PubMed, EMBASE and reference lists revealed a total of 90 reported cases of iris microhaemangiomas. To our knowledge, no previous reports have described concurrent findings of iris microhaemangiomas and idiopathic juxtafoveolar retinal telangiectasis in a patient. Both conditions are acquired vascular diseases, but their pathogenesis and aetiologies are unknown. Iris microhaemangiomas are important clinically because they are occasionally a cause of spontaneous hyphaema and may induce transient elevation of intraocular pressure.
我们描述了一例虹膜微血管瘤（虹膜血管丛）导致自发性前房积血的病例，检查发现该患者还患有特发性黄斑旁视网膜毛细血管扩张症。通过检索PubMed、EMBASE及参考文献列表进行系统搜索，共发现90例已报道的虹膜微血管瘤病例。据我们所知，此前尚无关于患者同时存在虹膜微血管瘤和特发性黄斑旁视网膜毛细血管扩张症的报道。这两种疾病均为后天性血管疾病，但其发病机制和病因尚不清楚。虹膜微血管瘤在临床上很重要，因为它们偶尔会导致自发性前房积血，并可能引起眼压短暂升高。
