What Researchers Did
Researchers reported the first case of multiple branch retinal artery occlusions following a new facial cosmetic filler (Poly-D, L-lactic acid) injection.
What They Found
A 23-year-old female experienced sudden blindness after receiving a Poly-D, L-lactic acid (PDLLA) injection at the glabella. Following emergency treatments, her best-corrected visual acuity improved from hand motion at 30 cm to 0.3 within two months. This case highlights a rare but devastating retinal artery occlusion, despite PDLLA's prior safety evaluation in 16,000 human cases.
