Intraocular nematodiasis in a llama (Lama glama)

Bettina Dunkel et al. Can Vet J. 2011 Feb.

Abstract
in English, French

This report describes a unique case of presumed migration of Parelaphastrongylus tenuis through the spinal cord into the eye of a llama where it survived and matured within the ocular environment. Blindness of the eye was most likely attributable to migration of the parasite through the central nervous tissue.

Infestation par les nématodes intraoculaire chez un lama (Lama glama). Ce rapport décrit un cas unique de migration présumée de Parelaphastrongylus tenuis dans la colonne vertébrale jusque dans l’œil d’un lama où il a survécu et est parvenu à maturité dans l’environnement oculaire. La cécité de l’œil a été le plus probablement attribuable à la migration du parasite dans les tissus du système nerveux central.
