You have pattern dystrophy if prestigious Wilmer says you do because they have the better experts, smarter top docs, like at the Mayo Clinic and expensive machines to diagnose this. The others have misdiagnosed you . Unless Wills or other prestigious clinics say its AMD then you need further testing. AMD does not take decades to progress its rather quick to progres but pattern dystrophy can take decades. It’s not AMD and it not a predictor of AMD. AMD is not drusen its just another word for word macular degeneration.
I wont respond any further. You are very lucky you don't have AMD and should not worry. I would take a prestigious eye clinics word as gospel.
