A 41-year-old woman presented with a hyphema in her right eye. Clinical examination revealed a vascular lesion of the iris that had enlarged over a 6-month period. The patient had no other evidence of ocular or cutaneous vascular malformations. Subsequently she experienced recurrent episodes of spontaneous hyphema, and there was objective evidence of growth of the lesion. Consequently, the lesion was excised by means of a sector iridectomy. Histopathological examination showed several large vascular compartments separated by thin, fibrous septa and lined by endothelium, consistent with a cavernous hemangioma. A benign iris melanocytic lesion was identified adjacent to the cavernous hemangioma. The intraocular pressure in the affected eye remained normal after the lesion was removed. After 6 months of follow-up no new hyphemas had developed. Iris cavernous hemangioma should be added to the differential diagnosis of recurrent hyphema.
一名41岁女性因右眼前房积血就诊。临床检查发现虹膜有一血管病变，在6个月内有所增大。患者无其他眼部或皮肤血管畸形的证据。随后，她反复出现自发性前房积血，且有病变生长的客观证据。因此，通过扇形虹膜切除术切除了病变。组织病理学检查显示有几个大的血管腔，由薄的纤维间隔分隔，内衬内皮细胞，符合海绵状血管瘤。在海绵状血管瘤附近发现了一个良性虹膜黑素细胞病变。病变切除后，患眼眼压保持正常。随访6个月后，未出现新的前房积血。虹膜海绵状血管瘤应列入复发性前房积血的鉴别诊断。
