Immune-mediated disorders of the eye: part two – equine recurrent uveitis

Abstract

Despite the immune-privileged status of the eye, immune-mediated ophthalmic disorders are reasonably common in many species. This article is the second of two articles discussing those most relevant to the horse and focuses on equine recurrent uveitis (the first article covered disorders of the cornea). Equine recurrent uveitis presents in three different forms that vary greatly in their clinical presentation. Importantly, many cases show no overt signs of ocular pain and diagnosis is often delayed until advanced damage has occurred. Several treatment options are available and must be tailored toward each case, with owners made aware of realistic expectations from the outset.
