Q: How likely is someone to experience blindness as a result of a procedure involving dermal fillers?
A: SW1’s Dr Low noted that the filler AestheFill is a Poly-L-lactic acid (PLLA) biostimulatory filler, which stimulates collagen production in the skin over time.Arterial occlusion – where blood flow through an artery is blocked – can occur if PLLA is inadvertently injected into a blood vessel.
Blindness following filler injection into the nasolabial lines – which extend from the nose to the corners of the mouth, and are also known as laugh lines – can occur due to a rare complication known as retinal artery occlusion.
This can happen if the filler is inadvertently introduced into a nearby blood vessel, she explained.
The filler material can travel through blood vessels, eventually reaching the ophthalmic artery, which supplies blood to the retina, the innermost tissue layer of the eye which processes images.
“Once the filler obstructs the retinal artery or its branches, it can lead to a sudden and severe reduction in blood flow to the retina,” said Dr Low.
“This results in a condition called retinal artery occlusion which, if not promptly addressed, can cause permanent damage to the retina and result in vision loss, including blindness.”
She added that preventing this complication involves a thorough knowledge of facial anatomy, precise injection techniques, and awareness of the potential risks associated with filler procedures.
