Epidemiology And Outcomes Of Endophthalmitis In Chronic Dialysis Patients: A 13-year Experience In A Tertiary Referral Center In Taiwan
Published 2017 · Medicine
BackgroundEndophthalmitis is a severe eye infection leading to disabling outcome. Because there were only a few case report illustrating endophthalmitis in chronic dialysis patient, we would like to investigate the epidemiology and clinical features of endophthalmitis in chronic dialysis patient in a tertiary referral center.MethodsWe searched the health information system in the study hospital with ICD9 encoding endophthalmitis during Jan. 2002 to Dec. 2015. A total of 32 episodes of endophthalmitis occurred in chronic dialysis patients. We performed an 1:2 case-control match on propensity score. The demographic features, clinical manifestation, infection focus and visual outcome were recorded.ResultsOf the total of 32 patients, 25 were classified as endogenous endophthalmitis and another seven were exogenous. Most patients presented with ophthalmalgia (n = 32, 100%) and periocular swelling (n = 31, 96.8%), whereas half of the patients suffered blurred vision (n = 16, 50%). Staphylococcus aureus, Klebsiella pneumoniae, and Pseudomonas aeruginosa were the most frequent causative pathogens. Dialysis vascular infection was also a possible unique focus for bacteremia. The visual acuity of the endogenous groups were less likely to improve in the chronic dialysis patients compared with control group.ConclusionThis is the first and the largest case series focusing on endophthalmitis in chronic dialysis patients. Our study showed different pathogen spectrum, an unique bacterial origin and worse visual outcome in these group of patients. Prompt referral to ophthalmologists when the patients present with suspicious symptoms (blurred vision, ophthalmalgia and periocular swelling) is crucial.
