Hi Wayne, My eye disease is inflammatory, not parasitic. This disease is usually found in Rheumatoid arthritis or lupus and causes swelling at the back of the eye,( this has previously damaged the retina and my optic nerve), as well as frontal swelling of my eyelid. Movement of my eyes causes arthritic like pain. I see it, excuse the pun, as part of the inflammatory disorder of ME. If I don't take the steroids to reduce the inflammation, I will go blind. The normal levels of Cortisol and other hormones are disturbed by this illness, which in turn leads to inflammation in various parts of the body as part of the disease process. The talk by Dr Nancy Klimas given late in 2009 gives a very good explanation of what happens in our bodies with this vile and so misunderstood illness. Thankyou for thinking of me, I will check out your link.
