What Researchers Did
Researchers reported a case of monocular vision loss following hyaluronic acid filler injection into the ear.
What They Found
A 45-year-old woman experienced immediate left-sided vision loss after ear filler injection, diagnosed as central retinal artery occlusion with only the inferior temporal visual field remaining. Following treatment with hyaluronidase, dexamethasone, hyperbaric oxygen, and alprostadil, her vision improved with partial blood flow restoration in the left ophthalmic artery.
What This Means for Canadian Patients
Canadian patients considering ear filler injections should be aware of the rare but serious risk of vision loss due to ophthalmic artery occlusion. It is crucial to discuss potential complications with a qualified practitioner who has a thorough understanding of facial anatomy.
Canadian Relevance
This study has no direct Canadian connection.
Study Limitations
As a single case report, this study's findings cannot be generalized to a broader patient population.
