Purpose
Acute visual loss after facial injection of cosmetic materials is rarely reported. In this study, we report one patient who developed acute visual loss after an injection of botulinum toxin A for esthetic purposes.
Methods
A 43-year-old Korean woman presented with a decrease in visual acuity to 20/800 after an injection of botulinum toxin A in the masseter muscle. The visual field testing showed an inferior altitudinal defect, and fluorescein angiography revealed a delayed arm-retinal circulation time.
Results
After intravenous and oral prednisolone was administered, the patient’s visual acuity gradually improved. Two months after the botulinum toxin A injection, the visual acuity had almost returned to baseline, with a remaining paracentral scotoma.
Conclusions
This is the first case of acute visual loss following an injection of botulinum toxin A in a facial lesion. This case emphasizes that the potential risks of botulinum toxin A injection should be considered, and the procedure should be performed delicately.
