Branch retinal artery occlusion after periocular dermal filler injection.

[PURPOSE] To report a case of branch retinal artery occlusion, choroidal ischemia, ischemic optic neuropathy, and suspicious traumatic optic neuropathy after periocular dermal filler injection.

[METHODS] History taking and ocular examinations were performed to find out the cause of sudden visual loss.

[RESULTS] On the fundus examination, occluded branch retinal artery was filled with long, fragmented, transparent materials which might be injected dermal filler. Fluorescein angiography showed arterial filling time delay with long, fragmented materials obstructing superior temporal retinal artery, nonperfusion areas around the occluded retinal artery territory, filling defect at temporal half of optic disk, and choroidal filling defect at nasal aspect of the retina.

[CONCLUSION] When injecting dermal filler, ocular complications should be considered.
