Abnormally distributed branches of the retinal vessels, enlarged macular arteries and long cilioretinal arteries.

We examined fundus photographs of 3,506 eyes and noted uncommon retinal vessel patterns in the temporal quadrants of the posterior fundus. Of 1,753 subjects, 20 patients (21 eyes) had unusual retinal vessel patterns. Seven eyes had an abnormally distributed branch of the inferotemporal artery; 8 eyes had an enlarged macular artery. Of these 20 patients, 1 had visual complaints associated with the unusual vascular patterns.
