Anastomoses between vessels of the fundus may occur as congenital malformations or secondary to vascular diseases affecting the eye. Congenital anastomoses can be of the racemose hemangioma type, with severe malformation of the retinal vessels, ocular complications, and neurologic manifestations, or as simple A-V shunts with visual impairment but limited tendency to show other ocular or neurologic involvement. These anastomoses must be distinguished from other vascular malformations like telangiectasis (Leber, Coats) or the angiomatous lesions of von Hippel's disease. Secondary anastomoses may be confined to the retinal vessels or involve chorioretinal connections. Retinal anastomoses occur in vascular disorders like retinal vein occlusions, diabetes, periphlebitis and hemoglobinopathies. They are often amenable to treatment by light coagulation. Chorioretinal anastomoses occur whenever Bruch's membrane is destroyed by traumatic, inflammatory, degenerative or physical (light coagulation) influences. Light coagulation may be the appropriate treatment, although complications are not rare.
眼底血管之间的吻合可能作为先天性畸形出现，或继发于影响眼睛的血管疾病。先天性吻合可以是蔓状血管瘤类型，伴有视网膜血管严重畸形、眼部并发症和神经学表现，或者是简单的动静脉分流，伴有视力损害，但显示其他眼部或神经受累的倾向有限。这些吻合必须与其他血管畸形区分开来，如毛细血管扩张（莱伯病、科茨病）或冯·希佩尔病的血管瘤样病变。继发性吻合可能局限于视网膜血管，或涉及脉络膜视网膜连接。视网膜吻合发生于视网膜静脉阻塞、糖尿病、周边静脉炎和血红蛋白病等血管疾病中。它们通常适合用光凝治疗。只要布鲁赫膜受到创伤、炎症、退行性或物理（光凝）影响而被破坏，就会发生脉络膜视网膜吻合。光凝可能是合适的治疗方法，尽管并发症并不少见。
