Putative non-uniting double central retinal artery system.
OBJECTIVE
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.
