Résumé
It has been reported that peripapillary loops develop after central retinal artery occlusion (CRAO). Although cilioretinal anastomoses have been shown by fluorescein angiography (FA) and indocyanine green angiography, these examinations cannot confirm the structural continuity between the retinal arteries and the posterior ciliary arteries. In the current report, we followed a patient with iatrogenic CRAO in which circumpapillary collaterals formed and assessed the connection between these two vascular systems using optical coherence tomography angiography (OCTA). Iatrogenic CRAO developed in the left eye of a 30-year-old woman during preoperative embolization of a convexity meningioma. FA and OCTA showed complete impairment of the retinal circulation. Two weeks after this event, OCTA images showed flow in the retinal vessels and the beginning of collateral vessel development on the optic disc margin. Six months later, OCTA images showed that these circumpapillary collaterals connected branches of the retinal arteries with the vessels supplying the optic disc, which originate from the posterior ciliary arteries. OCTA aided our understanding of the three-dimensional configuration of the circumpapillary collaterals that developed after iatrogenic CRAO, which included anastomosis of the retinal and posterior ciliary artery systems. OCTA is useful for noninvasively monitoring the status of retinal circulatory dynamics after iatrogenic CRAO.
