Severe bilateral ischemic retinal vasculitis following cataract surgery.

This report describes two cases of severe, bilateral ischemic retinal vasculitis following cataract surgeries at different surgical centers. In both cases, the patient underwent bilateral cataract surgeries, performed 1 week apart for each eye. In the perioperative period following the second of the two surgeries, both patients developed severe, bilateral intraocular inflammation and profound vision loss. The underlying cause of this adverse response remains unknown. The authors suggest that the severe inflammatory reaction could be related to an intraoperative intracameral vancomycin injection.
