An 8-year-old girl presented with a subretinal abscess after strabismus surgery. This was treated successfully with medial rectus suture removal, pars plana vitrectomy, intravitreal antibiotics, and intravenous antibiotics. Recovery was complicated by acute post-infectious retinal vasculitis after tapering high-dose corticosteroids, requiring an extended corticosteroid regimen over 2 months until resolution.
