What Researchers Did
Researchers reported the first known case of posterior ciliary artery occlusion caused by hyaluronic acid injections into the forehead for cosmetic purposes.
What They Found
A 41-year-old female experienced right visual loss 7 hours after hyaluronic acid forehead injections, diagnosed with posterior ciliary artery occlusion and embolic facial artery occlusion. Following treatment with hyaluronidase, hyperbaric oxygen, and other medications, her forehead and nasal skin improved, and vision recovered to hand movements.
What This Means for Canadian Patients
Canadian patients considering cosmetic facial fillers should be aware of the rare but severe risk of vision loss due to vascular occlusion. It is crucial to choose an experienced and qualified practitioner to minimize such risks.
Canadian Relevance
This case report has no direct Canadian connection.
Study Limitations
As a single case report, the findings have limited generalizability to the broader patient population receiving hyaluronic acid injections.
