Abnormally Distributed Branches of the Retinal Vessels, Enlarged Macular Arteries and Long Cilioretinal Arteries

Abstract

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 that was uncommonly long, and 6 had a longer than usual cilioretinal artery. Of these 20 patients, 1 had visual complaints associated with the unusual vascular patterns.

Congenital retinal macrovessel with intracranial venous malformation in a pediatric patient: a case report

“…C ongenital retinal macrovessel (CRM) is defined as an abnormal large retinal vessel that encircles the foveal avascular zone (FAZ) [1] . Since the first description of a large aberrant vessel crossing the macula by Mauthner [2] in 1868, there have been several case reports about CRM [3][4][5][6][7][8][9][10] . And recently, Pichi et al [1] reported clinical manifestations and multimodal retinal imaging of 49 eyes with CRM.…”

“…On fundus examinations, the CRM remained stable, and complications associated with macrovessels were not observed. Previous studies on retinal macrovessels are mostly in the form of case reports [7][8][10][11][12][13] ; therefore, the accurate prevalence of CRM is unclear; however, Hayasaka et al [9] reported that unusual retinal vessel patterns were found in 21 of 3506 eyes in their retrospective fundus photographs analysis. Meanwhile, among previous case reports of CRM, pediatric cases have only rarely been reported [7][8]11] .…”
