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.
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.
