Pulsating Cilioretinal Artery From Ocular Hypertension

High intraocular pressure (IOP) is a risk factor for retinal vein occlusion, and cilioretinal artery obstruction can follow because the choroidal circulation lacks the ability to autoregulate and compensate for an elevated resistance to flow imposed by a high IOP. This real-time video shows angiographic manifestations of cilioretinal artery obstruction: a pulsating cilioretinal artery with sluggish venous laminar filling at least 10 seconds after arterial filling and significant delay of both arterial and venous filling in the inferotemporal macula corresponding to the distribution of the pulsating cilioretinal artery.
