Hopefully the expert will give you good news. Even if it is retinitis pigmentosa, there's hope though. That condition is caused by problems with the eye itself, which means that a visual prosthesis would work for you. The technology is still primitive and experiemental, but it has advanced enough that early versions are already available to the public, albeit at a high price. After another 10 to 20 years of improvements, they will certainly become significantly cheaper and more advanced. It's entirely possible you could end up with an implant that gives you 20/20 vision and night vision as well.
