Dear John, If your doctor did not inform you then we will now. Idebenone is not a cure for LHON, Retinitis pigmentosa, Macula changes . . . what it is, is a way to manage these respective diseases. In fact, there are four different mutations for LHON and they can present at almost any stage in life, from 6 years to even 75 years of age. No competent doctor in the world would ever make the claim that idebenone will restore your eyesight. The results from taking the appropriate idebenone dosage (usually 900 mgs per day) with fat food is quite varied. Some patients have experienced extraordinary results. Some are driving cars, again, visiting museums, watching TV . . . and are considered no longer legally blind. Others, not so much. Nothing. In other cases they just don't get worse. The research goes on. As of today there is no cure for LHON and RP. There is not a drug, eyedrop or even stem cell procedure on the market that will make you good as new. Please feel free to visit www.pubmed.gov to review all of the idebenone studies relating to your disease. All of the best studies are located there. As of right now idebenone is all you have to impact your disease. One day there will be a cure but until then Idebenone is all there is. The particular formulation, Effinex with vitamin C, was developed by the most respected LHON research physician in the world. He developed it at UCLA through our lab. All of his patients take it with varying levels of success. In some cases it takes as long as 18 months to make a difference. If it is going to make a difference at all. Please don't forget to take it with fat foods as it is fat soluble and will absorb deeper and longer in the critical optic cells.
