title: Arterial vascular anomalies of the retina.
abstract: The incidence of nonaneurysmal congenital anomalies of the retinal arteries was determined by ophthalmoscopic examination of the eyes of 2,100 consecutive healthy individuals whose ages ranged from 6 to 68 years. Unusual anomalies were triple branching, anomalous course, arteriolar-arterial crossing, unusual tortuosity, prepapillary loops, aberrant macular arteries, unusual supply of the optic disc, presumed total ciliary arterial supply of the retina, anomalous relationship with the central retinal vein at the optic disc, and pseudoaneurysm of a major retinal artery. Cilioretinal arteries are the commonest of the congenital vascular anomalies of the retina.
