Infectious orbital complications after strabismus surgery are rare. Their incidence is estimated to be 1 case per 1,100 surgeries and include preseptal cellulitis, orbital cellulitis, subconjunctival and sub-Tenon's abscesses, myositis, and endophthalmitis. This report describes the case of an otherwise healthy 3-year-old boy who underwent bilateral medial rectus recession and disinsertion of the inferior obliques. A few days after surgery, the patient presented with bilateral periorbital edema and inferotemporal chemosis. A series of CT scans with contrast revealed inferotemporal orbital collections OU. The patient immediately underwent transconjunctival drainage of fibrinous and seropurulent collections in the sub-Tenon's space and experienced rapid improvement a few days later. The patient is reported to be in stable condition in a follow-up examination performed more than a year after the reported events.
