Abstract

Purpose:

To report the clinical features, treatment modalities, and visual outcomes in 12 eyes with endogenous Klebsiella pneumoniae endophthalmitis (EKPE).

Methods:

The medical records of all patients diagnosed with EKPE at Stanford Hospital (Palo Alto, CA) and Santa Clara Valley County Hospital (Santa Clara, CA) from January 2000 to March 2017 were retrospectively reviewed.

Results:

A total of 10 patients (12 eyes) were diagnosed with EKPE. The median age at presentation was 56, 80% were male, and 30% were non-Asian. Presenting visual acuities ranged from 20/20 to no light perception. Of the 12 eyes 10 received a tap and injection (range, 1–33 injections per eye), 2 eyes underwent primary enucleation or evisceration, and 1 patient underwent pars plana vitrectomy after tap and injection. Final visual acuities ranged from no light perception (six eyes) to 20/300 or better (five eyes). Five patients eventually underwent evisceration or enucleation. All cases were associated with positive blood and/or vitreous cultures and had concurrent systemic infection.

Conclusion:

Endogenous Klebsiella pneumoniae endophthalmitis is a rare, but devastating, ocular infection. Most cases in this series resulted in light perception vision or worse, and almost half required enucleation or evisceration. In light of the virulence of EKPE, early diagnosis and treatment should be initiated in all suspected cases.
