Epicanthal folds are caused by a flronu/deadeveltped nose. They are "shed" when the nose develops normally (which it does not in Down's syndrome, for example).Yes, maybe that is all there is to epicanthic folds.The nasal bridge - the bony part of the nose between the eyes - projects outward from the face and naturally tugs on the skin around it, including presumably the skin of the eyelid.If there is no nasal bridge, or if it's very flat, there is not going to be this tugging action that stretches the skin of the eyelid, resulting in epicanthic folds.Perhaps that is the explanation.
