Abstract

IN INDIVIDUALS suffering from occlusion of the central artery the residual vision is determined by the amount of retina supplied via the dliary circulation, which in most individuals is limited to the area surrounding the disk. How-ever, in approximately 14 to 21% of the population a cilioietinal artery is present that can supply the macula and afford good central vision.1 Much more rarely, if the cilioretinal artery is occluded, macular vision may be reduced. While occlusions of the cilioretinal artery have been described, the following case is unusual in that the occlusion was probably secondary to an embolus in an individual having subacute bacterial endocarditis.
