Ophthalmic Disorders Observed in Pet Chinchillas (Chinchilla lanigera)

This article presents a retrospective analysis of ocular disorders observed in outpatient pet chinchillas examined in a veterinary clinic between 2000 and 2010. The most common ophthalmic conditions diagnosed during this time period was alteration of the lens (15 eyes, 10 chinchillas), followed by abnormalities of the cornea (14 eyes, 13 chinchillas), and conjunctival disease (10 eyes, 9 chinchillas). The predominant lens disorder was cataracts, whereas the main alteration of the cornea was fluorescein-positive corneal substance loss. Subtle ocular changes appear to be common in the chinchilla. The data gathered within this study indicate that a thorough ophthalmic evaluation is warranted during routine physical examinations for this species.
