Horner's Syndrome in Horses

What is Horner's Syndrome in horses? Basically it is a neurological condition or some kind of dysfunction in the sympathetic nervous system. The condition usually affects the horse's eye, facial muscles or sweating. It is not painful and does not affect the horse's vision. Horner's Syndrome may present in several ways including, drooping eyelids, sunken eyes (not due to a horse's age), a raised or swollen third eyelid, constricted pupils, or noticeable sweating on the side of the infected eye.

There can be underlying medical conditions such as injury, ear infections, spinal cord tumors, blood clots, eye disease, bites to the head or neck and trauma to the neck. Treatment depends upon what the underlying cause may be. If the spinal cord or brain are not involved then the prognosis is better.
