Abstract
This article discusses the clinical appearance, differential diagnoses, and treatment considerations of corneal disease in the most common domesticated species of rodent: mouse, rat, chinchilla, and guinea pig. Many corneal diseases are related to inbred strains of either research or pet rodents. Diseases are complicated by husbandry and treatment-related challenges in this small, social species. This article is broken down by species, first discussing normal anatomy, then discussing commonly encountered diseases, and concluding with treatment considerations.
