We examined the relationship of cilioretinal arteries (CRAs) to juxtapapillary chorioretinal scars, along with the developmental significance of the latter in relation to CRA formation. Both eyes of 360 patients were studied. Sixty-eight (18.9%) of these patients had a CRA in at least one eye, 13 of these 68 (19.1%) had one in both. The CRAs were distributed equally between right and left eyes. Two hundred eight patients (57.8%) had a scar in at least one eye; 157 of these (75.5%) had one in both. The presence of a CRA was significantly associated with the presence of a scar. Since both are common developmental variations, this correlation points to a common embryologic formation mechanism.
我们研究了睫状视网膜动脉（CRA）与视乳头旁脉络膜视网膜瘢痕的关系，以及后者在CRA形成方面的发育意义。对360例患者的双眼进行了研究。这些患者中，68例（18.9%）至少一只眼睛有CRA，其中13例（19.1%）双眼都有。CRA在右眼和左眼的分布相等。208例患者（57.8%）至少一只眼睛有瘢痕；其中157例（75.5%）双眼都有。CRA的存在与瘢痕的存在显著相关。由于两者都是常见的发育变异，这种相关性表明存在共同的胚胎形成机制。
