Equine Recurrent Uveitis (ERU)


Equine recurrent uveitis is one of the most common ocular diseases in horses, usually characterized by episodes of active inflammation followed by varying periods of quiescence. During the quiet periods, low-grade, subclinical inflammation may continue in at least some individuals. Regardless of the specific course, the inflammatory events eventually lead to secondary changes.  This syndrome is the most common cause of blindness. Many pharmaceutical medications are helpful, but can become quite expensive and difficult to administer into the eye frequently. Natural anti-inflammatories as well as immune regulating supplements offer better long-term treatment in many cases.





The following nutraceuticals or natural/herbal formulas and alternative therapies can also provide effective treatment and relief for your equines dealing with ERU.
