Incidence of chorioretinitis and endophthalmitis in hospitalized patients with fungemia

Aim/purpose Bloodstream candida infections can seed the eye via hematogenous spread and result in chorioretinitis or endophthalmitis. If undetected and untreated, this can result in permanent vision loss. Past studies evaluating incidence of ocular candidiasis among hospitalized patients with positive fungal blood cultures have demonstrated variable rates of occurrence, but recent studies have generally shown a lower incidence than was reported several decades ago. Given low rates of occurrence, the utility of screening patients with dilated fundus exams has been called into question. The primary aim of this investigation is to identify the rate of chorioretinitis and endophthalmitis based on dilated fundoscopy for patients with fungemia at a tertiary care hospital. Methods This study was a retrospective chart review of adult patients admitted to the medical centre of the University of Arkansas for Medical Sciences (UAMS) between May 1, 2014 and December 31, 2017, who had positive fungal blood cultures during their hospitalization. Results There were 324 positive fungal cultures in 290 patients. Of this initial group, there were 161 eye exams. Ocular examination identified 7 of 161 patients (4.3%) with chorioretinitis or endophthalmitis. Discussion These outcomes along with previous studies support the current guidelines that screening with dilated fundus examination for these patients is appropriate and necessary.
