Conditions and agents which have been implicated include '''leptospirosis''', brucella, strangles, '''Equine Influenza'''. ''Leptospira spp'' have been the most commonly investigated however their relationship with the disease remains obscure.

==Diagnosis==

The '''recurrent history and the typical clinical signs''' are required to make a diagnosis of Equine Recurrent Uveitis. It is important to differentiate between other causes of ocular inflammation such as herpesvirus infection or immune-mediated keratitis.

'''Flunixin''' is administered systemically and systemic steroids have also been used successfully although care should be taken in the detection of laminitis which can follow treatment.

Initial treatment should be continued for '''at least 2 weeks and tapered over a further 2 weeks''' after clinical signs resolve.

In some horses, the severity and frequency of the bouts of inflammation increase, and surgery might be an option to consider.
