From: Cilioretinal Arteries and Cilioretinal Veins in Eyes with Pathologic Myopia
Cilioretinal arteries (CAs) deriving from the Zinn-Haller arterial circle (ZHAC). (A) Fundus photograph of a right highly myopic eye with an axial length of 28.1 mm. The CA (arrowheads) emerges from the border between parapapillary gamma zone (outlined by yellow arrowheads) and parapapillary delta zone (outlined by blue arrowheads) outside of the optic disc. (B) Arterial phase of the ICGA shows the ZHAC (arrow) in the temporal region and the CA (black arrowheads) derived from the ZHAC. (C) Venous phase of the ICGA. The CA (arrowheads) derived from the ZHAC (arrow) can visualized. (D) Right fundus of the eye of a 67-year-old woman with a temporal CA (arrowheads). (E) Arterial phase of the ICGA shows the ZHAC (arrow) and a CA (arrowheads) originating from the ZHAC. (F) Venous phase of ICGA. A CA (arrowheads) originating from the ZHAC (arrow) can visualized. (G) ICGA of the right fundus of the eye of a 29-year-old man. Axial length is 27.8 mm. A CA (arrowheads) deriving from the ZHAC (arrows) can be visualized outside of the optic disc.
