Objective: To report the clinicopathologic features of four eyes enucleated for late-onset bleb-related endophthalmitis.
Study design: Retrospective case series.
Materials: Four enucleated eyes.
Methods: The clinical and histopathologic features of four patients who underwent enucleation for late-onset endophthalmitis after glaucoma filtering surgery were reviewed.
Results: The eyes were enucleated for endophthalmitis one to five years after trabeculectomy. Two of the four eyes had trabeculectomy with adjunctive mitomycin-C. All four eyes had streptococci cultured from the aqueous and/or vitreous. Common pathologic features included inflammation involving the anterior segment, lens and choroid. One eye exhibited focal granulomatous uveitis.
Conclusions: Late-onset endophthalmitis after glaucoma filtering surgery is often due to streptococcal species and rapidly progresses over a few days. Phacoanaphylaxis with associated granulomatous uveitis may contribute to the poor prognosis in this setting.
