A.Pannus is a general covering that forms on the cornea of the eye, typically in German Shepherds. Eyes are the gateways to the body and eye problems can usually often be associated with a deeper liver problem. You’ve probably heard people say that eating carrots is good for your vision. Actually carrots contain vitamin A, which has more of a pronounced effect on the liver than on the eye itself. In Chinese medicine, the acupuncture points for eye function are the same ones associated with liver function. For this type of thing, I would do a metabolic balancing of the system, focusing on the liver function. I would use glandulars to help accomplish this as well as a supplement called Visioplex by Progressive. You could also use the Herbal Eyewash Kit by Halo or the topical homeopathic Similasan 1.
