Abstract
- We investigated the clinical characteristics of cilioretinal arteries (CAs) and cilioretinal veins (CVs) in eyes with pathologic myopia. Ninety-five eyes with pathologic myopia and CAs were studied. The retrobulbar vessels from which the CAs originated were identified by indocyanine green angiography (ICGA). The results showed that 114 CAs were identified in the 95 eyes. ICGA showed that 60% of the CAs branched directly off the short posterior ciliary arteries (SPCAs) and 40% originated from the Zinn-Haller arterial circle (ZHAC). The SPCA-derived CAs tended to be located superiorly and served a large retinal area whereas the ZHAC-associated CAs tended to be located temporally and served mainly the macular area. In 15% of the 95 eyes, the CVs were observed to run parallel to the CAs. The CVs exited the eye at the same point where the CAs entered the eye. This study showed that CAs in eyes with pathologic myopia can be divided into those that are SPCA-derived and tend to emerge in the superior optic disc sector, and those that are ZHAC-associated and usually emerge temporally. An elongating peripapillary scleral flange in eyes with progressive axial myopia may lead to a change of chorioretinal vascular system.
