Central retinal artery occlusion as an iatrogenic complication of treatment of central giant cell granuloma of the mandible.

Although intralesional steroid injection as a management option for central giant cell granuloma (CGCG) of the mandible is considered safe, central retinal artery occlusion (CRAO) is a dreaded and previously unreported complication of this treatment modality. The present report discusses an iatrogenic case of CRAO that occurred during treatment of CGCG of the mandible. This complication occurred because of high injection pressure, which led to the opening of an anastomosis between the external and internal carotid arteries, leading to retrograde migration of steroid particles. This report also highlights the importance of being aware of such communications.
