Case report showing Acell leading to blindness via retinal artery embolization

[consequence]

This is a recent published article from Johns Hopkins about Acell (urinary bladder matrix) causing blindness in a patient because of embolization into the retinal artery:

Study

Quote

 A 64-year-old female presented with acute-onset OD pain and decreased visual acuity after subcutaneous injection of acellular porcine urinary bladder matrix at the hairline. Fundus examination revealed multiple emboli at retinal arcade branch points, and fluorescein angiography demonstrated corresponding areas of peripheral nonperfusion.

OD means the right eye.

Probably similar to how you can get embolization from injecting filler or a nose job. This is only a case report so no way to know the actual risk until larger studies come out but yikes.
