Contact lens-associated fusarium keratitis in Switzerland


Kaufmann, C; Frueh, B E; Messerli, J; Bernauer, W; Thiel, M A (2008). Contact lens-associated fusarium keratitis in Switzerland. Klinische Monatsblätter für Augenheilkunde, 225(5):418-421.

Abstract

BACKGROUND: Fusarium has been an exceptionally rare cause of infectious keratitis. A recent outbreak of Fusarium keratitis in contact lens wearers in North America and Asia has been associated with the multipurpose disinfection solution ReNu with MoistureLoc (Bausch&Lomb). We report a series of Fusarium keratitis in Swiss contact lens wearers. PATIENTS AND METHODS: A multicentre retrospective case review of patients with corneal ulceration and a positive microbiological identification of Fusarium species was undertaken. RESULTS: Between September 2005 and August 2007, six cases of Fusarium keratitis were identified. Patients were 39 to 63 years of age. All patients were using disposable soft contact lenses for at least two years. Four patients used daily wear disposable lenses. Two patients were wearing 1-monthly disposable lenses and used ReNu with MoistureLoc solution. Due to multiresistant Fusarium, enucleation was required in two cases and an emergency keratoplasty was performed in three cases. An optical keratoplasty was undertaken in one case that developed corneal scarring. Final visual acuity in patients with preserved eyes ranged from light perception to 8 / 20. CONCLUSIONS: Exposure to ReNu with MoistureLoc is not the only risk factor for Fusarium keratitis. In addition to antifungal therapy, an early keratoplasty with excision of the infected tissue seems mandatory to improve prognosis.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
