In a study carried out on 123 eyes to establish the incidence of dual trunk central retinal vein, 25 (20.5%) eyes showed such an arrangement. The presence of such anomalies has also been substantiated through the results of anatomical, histological, and microdissectional studies by various workers. The zone of the retina drained by the individual central retinal vein varied from 30% to 70%. The arrangement was not only superior or inferior, but could also be medial, lateral, diagonal, or crossed. The clinical relevance of this finding is a newly described fundus condition called hemi-central retinal vein occlusion.
在一项针对123只眼睛进行的研究中，为确定双主干视网膜中央静脉的发生率，有25只（20.5%）眼睛呈现出这种结构。其他研究人员通过解剖学、组织学和显微解剖学研究结果也证实了此类异常情况的存在。由各条视网膜中央静脉引流的视网膜区域从30%到70%不等。这种结构不仅有上下之分，还可能是内侧、外侧、对角或交叉的。这一发现的临床意义在于一种新描述的眼底疾病，即半侧视网膜中央静脉阻塞。
