Combined central retinal artery and vein occlusion (CCRAVO) is a rare entity characterized by features of tortuous retinal veins, retinal hemorrhage, optic disk edema and pallor, macula edema, cherry-red spot, and cotton-wool spots. The occurrence of CCRAVO in the adult population is often in the setting of systemic disease; while CCRAVO in the pediatric population is frequently associated with infection of the sinuses, preseptal cellulitis, or orbital cellulitis. It has been hypothesized that CCRAVO can result from methicillin-resistant (MRSA) sepsis-induced coagulation disturbances, orbital cellulitis, and even orbital compartment syndrome; however, there are insufficient reports of this complication. This case report sheds light on one such case with irreversible vision loss as a sequela.
视网膜中央动脉和静脉阻塞（CCRAVO）是一种罕见的疾病，其特征为视网膜静脉迂曲、视网膜出血、视盘水肿和苍白、黄斑水肿、樱桃红斑和棉絮斑。成人 CCRAVO 的发生常与系统性疾病有关；而儿科 CCRAVO 常与鼻窦感染、眶前蜂窝织炎或眶蜂窝织炎有关。据推测，CCRAVO 可能是由耐甲氧西林金黄色葡萄球菌（MRSA）败血症引起的凝血功能障碍、眶蜂窝织炎甚至眶隔综合征引起的；然而，这种并发症的报道还不够充分。本病例报告就揭示了这样一个因该并发症导致视力不可逆转丧失的病例。
