Purpose: To identify the microbiological spectrum and visual outcome of bleb-associated endophthalmitis. Methods: The medical records of patients treated for bleb-associated endophthalmitis were reviewed. Results: Seventy-five patients were identified. Vitreous cultures were positive in 48 (64%) patients. The most common isolates were Streptococcus species in 24 (50%) eyes, gram-negative bacteria in 10 (20.8%) eyes, and Staphylococcus epidermidis in 7 (14.6%) eyes. Good visual outcome was achieved in 33 (44%) patients. On univariate analysis, shorter interval from onset of symptoms and treatment (p.005), better initial visual acuity (p.=004), clear cornea at presentation (p.=048), isolation of less virulent organisms (p<.001), and absence of diabetes mellitus (p.=048) were significant positive predictors for good visual outcome. Conclusions: Bleb-associated endophthalmitis is associated with severe visual impairment. Clinical features associated with better visual outcome include early presentation, better presenting visual acuity, clear cornea at presentation, culture of a less virulent organism, and absence of diabetes mellitus.
