Your question is confusing and not clearly stated. PVD occurs more commonly as we get older. The rough incidence is 10% per decade of life so by age 30 its 30% age 60% and age 90 90% So PVD and RD become more common as we get older. So your statement is wrong. PVD occurs more in older people and as we get older. RD is so unique that its not possible to generalize. The age is not as important as degree of myopia, status of retina, trauma, family history, etc.
