Actually the retina is made up of two layers that *attach or seal* together by birth. In retinal detachment the two layers do not attach to each other at all. When there are retinal folds that are tiny spots where the two layers do not attach to each other perfectly/smoothly--tiny imperfections. In geographic dysplasia there are larger spots where the two layers do not attach perfectly or smoothly. Sort of like taking two pieces of tape and putting them together, sticky sides facing each other. Of course we would find it very hard to put two pieces of tape together and most of us would end up with bubbles or imperfections where the two pieces didn't meet perfectly, but the analogy does make it easy to see how the folds can happen. I would wonder if once the two layers are attached to each other perfectly and smoothly resulting in no folds at all, if they could start to come apart for some reason later. Is that even possible?
