title: Central retinal artery occlusion.
abstract: Injecting steroid crystals into orbital inflammatory lesions produces a prolonged, high level of drug activity at the target tissue. This technique appears helpful in controlling orbital inflammations in problem cases while reducing the chance of steroid related systemic side effects. We report a patient who experienced central retinal artery occlusion from steroid particles injected into an orbit inflammatory mass. The mechanism of this complication and methods to reduce the chance of central retinal artery embolization are discussed.
