Dear Sylvia, this is not a reply to your message, but the Rare Disorder message hit my eye. My sister in Germany has had Scleroderma for several years. She functions almost normal with various medications and eye drops. Where can I find out more about the disease, and is it progressive and how rare is it? Also, are there any known causes? Would appreciate info on reading material I can peruse. Thanks, Johanna Willner
