PURPOSE: To report a case of inadvertent intraocular injection of botulinum toxin A (Botox, BTA) resulting in a retinal tear and bullous retinal detachment. The retinal detachment resolved spontaneously, and the tear was treated with laser demarcation with good visual outcome. DESIGN: Interventional case report. METHODS: A 36-year-old woman underwent Botox injections for paralytic esotropia and developed ocular perforation. Dilated fundus examination showed a slit-like retinal tear infranasally with a bullous retinal detachment nasally. RESULTS: The retinal detachment spontaneously resolved, and the patient was treated with laser demarcation on the following day. After 2 more days, her vision returned to baseline. CONCLUSIONS: Botox did not appear toxic to human intraocular tissues. Close observation may be indicated in the event of an inadvertent intraocular Botox injection.
