What Researchers Did
Researchers reported a case of retinal artery occlusion in a patient following a cosmetic injection of poly-L-lactic acid.
What They Found
They found that a 49-year-old woman experienced sudden central visual loss and severe ocular pain immediately after poly-L-lactic acid (PLLA) injection in the temporal region. Her best-corrected visual acuity in the right eye dropped from 20/20 to 20/200. Despite prompt aggressive management, she suffered permanent visual loss due to optic atrophy.
What This Means for Canadian Patients
Canadian patients considering cosmetic facial filler injections should be aware of potential, albeit rare, severe complications like permanent vision loss. It is crucial to discuss all risks and benefits with their healthcare provider before undergoing such procedures.
Canadian Relevance
This study has no direct Canadian connection as it is a case report from Taiwan.
Study Limitations
A key limitation of this study is that it is a single case report, which inherently limits the generalizability of its findings.
