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.
What This Means for Canadian Patients
Canadian patients considering facial cosmetic filler injections should be aware of the rare but serious risk of vision loss, even with newer products like Poly-D, L-lactic acid. Seeking immediate medical attention for any sudden visual changes after such procedures is crucial, as timely treatment can improve outcomes.
