Background and objectives: To assess the differences in history, clinical course, and response between five cases of blebitis and three cases of endophthalmitis following mitomycin trabeculectomy.
Patients and methods: The authors conducted a retrospective review of eight consecutive cases of bleb-related infection following successful mitomycin trabeculectomy.
Results: All patients with blebitis responded to treatment with return of visual acuity and intraocular pressure to preinfection levels. In the three cases of endophthalmitis, one patient underwent enucleation, one had a final visual acuity of counting fingers, and the third had a visual acuity of 20/60.
Conclusions: Blebitis, a limited form of bleb-related infection with thin, cystic, leaky blebs, responds to intensive topical antibiotic treatment, returning visual acuity and IOP to preinfection levels. Bleb-related endophthalmitis causes a more virulent form of bleb-related infection that involves thin- or thick-walled blebs, with or without leakage, and poor visual prognosis despite immediate intensive topical, systemic, and intravitreal antibiotic administration combined with core vitrectomy.
