Understanding equine recurrent uveitis (moon blindness) and how management and surgical intervention can preserve quality of life for affected horses.
Equine recurrent uveitis causes chronic pain during active flare episodes and progressive vision loss between them. The welfare impact is twofold: acute pain from intraocular inflammation, and the anxiety and behavioral changes that accompany progressive vision loss in a species that relies heavily on vision for safety and spatial awareness. Medical management of acute episodes with systemic and topical anti-inflammatories reduces pain during flares, while the cyclosporine implant represents a surgical option that reduces flare frequency significantly. Horses that do become blind adapt remarkably well with thoughtful management — maintaining consistent environments, using auditory and tactile cues, and allowing blind horses to navigate familiar spaces without frequent rearrangement of their environment.
