This patient presented with a painful red eye to the ER three years after an uneventful trabeculectomy. He was diagnosed with blebitis, but since he had 20/20 visual acuity, there was no anterior chamber inflammatory reaction nor posterior segment involvement. He was aggressively treated with topical broad-spectrum antibiotics and had daily visits. Fortunately, it resolved with no progression of the infection, although it should be regarded as a potential sight-threatening late complication of trabeculectomy. It would also had been reasonable to treat as an endophthalmitis with intravitreal antibiotics, which we would been treated anyway if the situation got any worse. The inflammatory reaction resulted, however, in bleb failure.
