Hello and thanks for your question.
First of all, as far as a standarized, accepted treatment to cure or reverse the effects of retinitis pigmentosa, there isn't a treatment available. However, there is exciting research going on into several key areas of treatment in RP, including gene therapy. You actually live very close to a good academic medical center where an eye institute is available that does research into RP. Their website is http://www.uic.edu/com/eye/. One of their articles about the research they are doing on RP is at http://www.uic.edu/com/eye/Department/News/eyedropsimproveRPshtml.html. Unfortunately, there is nothing that can be done to prevent this being transmitted to your child; if they've received the genes for it, then it may or may not express itself and if it does it may or may not express itself severely or completely.
Does that help answer your questions?
