Iatrogenic central retinal artery occlusion after carotid body tumor embolization and excision.

Objective

To report a case of iatrogenic central retinal artery occlusion after embolization and surgical resection of carotid body paraganglioma.

Methods

Case report

Results

One adult female patient presented with persistent unilateral visual loss after embolization with Embosphere® and Contour® microparticles of carotid body tumor. Fluorescein angiography revealed intraluminal microspheres in the central retinal artery ramifications. OCT revealed intraretinal spherical, hyporeflective particles with posterior shadowing.

Conclusions

Central retinal artery occlusion should be assessed as a possible complication after surgical repair of head and neck paragangliomas.
