Orbital emphysema complicated by acute central retinal artery occlusion: case report and treatment

Orbital emphysema is a well-known clinical entity that has been considered benign and requiring no treatment. A case of marked orbital emphysema with simultaneous central retinal artery occlusion is described. The prompt relief of this occlusion following aspiration of air from the orbit suggests that orbital emphysema is an unreported cause of central retinal artery occlusion.
