Abstract
Aims
To identify the clinical features and prognostic factors of endogenous endophthalmitis caused by Klebsiella pneumoniae.
Methods
This is a retrospective case series of all patients with Klebsiella endophthalmitis managed from January 2006 to December 2015 by Kowloon East Ophthalmic Service. Statistical analysis involved hypothesis testing on the SPSS 18.0 software (SPSS). A significance level of P<0.05 was taken.
Results
In the 10-year period, K. pneumoniae accounted for 19 out of 39 cases of endogenous endophthalmitis (48.7%). The mean age of patients was 67.9 years. Bilateral involvement occurred in five patients (26.3%). More than half of the patients (10/19, 52.6%) had underlying diabetes mellitus. Most patients had concurrent liver abscess (18/19, 94.74%). Ten patients (52.6%) had disseminated intravascular coagulopathy. Eight patients (42.1%) were in shock. The overall mortality was 21.1% (4/19). Septic shock was associated with a significantly higher mortality (50.0 vs 0%, P=0.018). Among the 15 survivors, nine patients (60.0%) required evisceration and three patients (20.0%) had no light perception in an involved eye. Eyes with diffuse posterior involvement were less likely to have a final visual acuity of logMAR 0.30 or better than those with focal posterior involvement (4.76 vs 100% 4.76%, P=0.002). Patients with hypopyon were more likely to require evisceration (85.71 vs 25.00%, P=0.02).
Conclusions
Klebsiella endophthalmitis is associated with a high incidence of diabetes mellitus and liver abscess. Prognosis remains poor. Universal ocular screening and systemic control in patients with Klebsiella sepsis are recommended.
