Fungal endophthalmitis after a single intravenous administration of presumably contaminated dextrose infusion fluid.
PURPOSE: To report fungal endophthalmitis in nonimmunocompromised patients, each of whom received a single intravenous administration of presumably contaminated dextrose infusion fluid for minor ailments in rural settings. METHODS: This noncomparative case series included 12 nonimmunocompromised patients (12 eyes) with culture-positive fungal endophthalmitis. All eyes underwent initial vitreous tap with injection of intravitreal antibiotics. Eleven eyes required pars plana vitrectomy and oral fluconazole or itraconazole for 4 to 6 weeks. One patient with panophthalmitis was treated with intravenous amphotericin B. To support the hypothesis that contaminated intravenous fluid was the possible risk factor, samples from 72 sealed bottles of 5% dextrose were subjected to fungal culture. RESULTS: Patients presented 1 to 11 weeks (mean, 4.6 weeks) after the intravenous infusion. All eyes had a positive smear and cultures for fungi. Aspergillus specimen was isolated in nine eyes, Candida in two eyes, and Mucor in one eye. Final visual acuity was 20/80 or better in 8 (66.6%) eyes. Eleven of the 72 samples from dextrose bottles were culture-positive for fungi: six for Aspergillus fumigatus, three for Aspergillus niger, and two for Candida albicans. CONCLUSION: A presumed contaminated intravenous infusion administered in a rural setting was found as a new risk factor for development of endogenous fungal endophthalmitis. These patients were successfully treated with pars plana vitrectomy and oral fluconazole and itraconazole therapy.
