Ulcerative fungal keratitis in a Brown Swiss cow


Voelter-Ratson, K; Monod, M; Braun, U; Spiess, B M (2013). Ulcerative fungal keratitis in a Brown Swiss cow. Veterinary Ophthalmology, 16(6):464-466.

Abstract

An 11-year-old Swiss Brown cow was referred to the Food Animal Department of the Veterinary Teaching Hospital in Zurich, Switzerland due to lateral recumbency of unknown origin. The animal had developed enophthalmos due to dehydration at the time of presentation. Two days after hospitalization, the cow showed blepharospasm and epiphora of the right eye and the Ophthalmology Service was consulted. Ophthalmic examination of the right eye revealed a fluorescein positive, paraxial, corneal superficial ulcer with focal edema and mild superficial neovascularization. Corneal, white, stromal infiltrates were seen at the edges of the ulcer bed. After initial treatment with topical antibiotics, an increase of corneal infiltrates was noted on re-examination 2 days later. Several punctate, fluorescein negative, stromal, white opacities were seen dorsal of the ulcer. Cytology showed fungal hyphae. Topical treatment with 2 % miconazole ointment, antibiotics and K-EDTA resolved the clinical symptoms within 6 days. Fungal culture and polymerase chain reaction (PCR) identified the fungal organism as Eurotium amstelodami.

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.
