Congenital retinal macrovessels are large aberrant branches of retinal arteries or veins that cross the macula. We present three patients with a unilateral congenital retinal macrovessel and we conduct a review of the literature.
A 22-year-old man complaining of chronic headache as well as two other men, 18 and 23 years old, respectively, during a routine ophthalmological examination, were found with a unilateral congenital retinal macrovessel each. A thorough ophthalmological examination was performed, including colour fundus photography in all three patients and fluorescein angiography in two of the patients. We followed them up for five years.
Investigation revealed a unilateral venous congenital retinal macrovessel in all patients. Clinical findings and visual acuity remained unchanged throughout the entire follow-up period. No complications were recorded.
Congenital retinal macrovessels are rare and they tend to remain stable. Visual acuity is preserved in most cases. Complications occur only occasionally and have been described in the literature. Differential diagnosis from other arteriovenous malformations affecting multiple organs is necessary.
先天性视网膜大血管是横跨黄斑区的视网膜动脉或静脉的粗大异常分支。我们报告三例单侧先天性视网膜大血管患者，并对相关文献进行综述。
一名22岁男性主诉慢性头痛，另外两名分别为18岁和23岁的男性在常规眼科检查中被发现患有单侧先天性视网膜大血管。对所有三名患者进行了全面的眼科检查，包括彩色眼底照相，其中两名患者还进行了荧光素血管造影。我们对他们进行了五年的随访。
检查发现所有患者均为单侧先天性视网膜静脉大血管。在整个随访期间，临床症状和视力均保持不变。未记录到并发症。
先天性视网膜大血管较为罕见，且往往保持稳定。大多数情况下视力得以保留。并发症仅偶尔发生，文献中已有描述。有必要与影响多个器官的其他动静脉畸形进行鉴别诊断。
