Abstract: Purpose: Raise awareness of a rare vision-threatening complication of botulinum toxin injections for strabismus. Report: A 22-year-old woman underwent bilateral lateral rectus muscle botulinum toxin injections for exotropia. She then developed complete vision loss in the left eye over a few hours, which partially resolved by the following day, leaving a temporal field defect. Steroids were administered at day five, which precipitated further improvement. However, a temporal field defect still remains. Conclusion: The underlying mechanism for this presentation is unclear, with trauma, compression, ischaemia or direct toxicity to the optic nerve and retina being possible. Ultimately, it is important to be aware of this complication so that patients can be consented adequately before receiving Botox treatment.
