Putative non-uniting double central retinal artery system
Purpose:
To report a case of probable non-uniting double retinal arterial circulation.
Methods:
Case report. A 66-year-old man suffered central retinal artery occlusion.
Results:
The medical findings and angiographic workup supported the existence of double central retinal circulation not uniting before entering the globe and independently branching in the retina.
Conclusions:
In previously recognized unusual anatomic structures of the central retinal artery two parallel arteries were recognized, both of which united before entering the globe. We have described a rare anatomic variant in which those arteries remained separated after entering the globe, including while branching in the retina.
