Background/purpose: To report a case of simultaneous endophthalmitis and anterior segment ischemia (ASI) that occurred in a patient after strabismus surgery. This is the first known case of both complications occurring at the same time.
Methods: Case report.
Results: A 60-year-old woman presented with eye pain and loss of vision 6 days after uncomplicated strabismus surgery for thyroid eye disease. On examination, she had corneal edema, anterior segment fibrin, an atonic iris, and no view to the posterior segment. On fluorescein angiography of the anterior segment, a large portion of the iris was nonperfused. Posterior segment ultrasound showed dense vitritis and a choroidal abscess. Intraoperative cultures grew methicillin-resistant Staphylococcus aureus.
Conclusions: Endophthalmitis and anterior segment ischemia are both exceedingly rare complications of strabismus surgery. It is possible that each one occurred independently, but more likely one process potentiated the other. One possible mechanism is inflammation-induced thrombosis.
