Sorry, can't help with info about Pattern Dystrophy, but I'd like to ask you some questions, if you don't mind.
I have some sort of retinal dystrophy (they haven't figured out just which layer yet) with a central scotoma in both eyes. I'm curious if other people with blind areas get a lot of activity in those areas -- e.g. oscillation, moving swirling blobs, lights, black spots, etc. Do you have any visual phenomena? I have a "flash-bulb" effect when I go from light to darkness. Will PD affect your peripheral vision?
I hope you're eating very well and taking supplements. There doesn't seem much else to do until gene therapy becomes a reality.
