Abstract
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 Staphylococcus aureus (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.
