Retinal artery emboli have been linked to facial cosmetic procedures. According to an article published in "The Review of Optometry", researchers at Seoul National University discovered that emboli may be caused by filler injections into peoples faces.
The patients had no underlying systemic diseases and suspect that the emboli reached the brain and thus eyes via the anterior communicating artery and the cutaneous collaterals in the midline. The researchers also found that there was retrograde spreading of the emboli materials resulting in retinal artery occlusions.
While these events are extremely rare, they must be considered when retinal vascular occlusions occur.
