Breakthrough in Using Stem Cells to Treat Retinitis Pigmentosa

February 25, 2011

Ophthalmology Times: Seven blind patients (retinitis pigmentosa) were injected with stem cells in a study by Dr. Francis at the Oregon Health and Science University. The cells were tolerated and not rejected. One patient noticed a small increase in light sensitivity. This is a good first step. As you can see, stem cell therapy is a long way off from giving patients useful vision, but at least we are on the right track. By the way, these stem cells were injected via a surgical vitrectomy and injected under the retina. Stem cell centers which promise vision by injecting via theĀ  retrobulbar route are selling an unproven therapy in my professional opinion. As I have said many times, I urge patients who want to try stem cells to seek out well-respected university settings and volunteer for studies.

    I have read a new stem cell treatment for retinitis pigmentosa by Dr Stephen Levy in Florida. This is the most positive treatment I have seen so far. What you know about this and your opinion. Thanks Barbara

    your story is saddening- i wish i could offer more encouragement. at the least, do not waste your precious money on things that dont work and that are designed simply to take your money away- there are many evil people out there who are happy to take advantage of you.
