A Historical Analysis of the Quest for the Origins of Aging Macula Disorder, the Tissues Involved, and Its Terminology

Although ocular tissues involved in aging macula disorder (AMD) were already known in 300 BC, the last type of photoreceptors was discovered only 10 years ago. The earliest descriptions of AMD appeared around 1850. It took over 150 years, till a clearer concept of AMD was formulated and even longer to grasp its pathophysiology. The uncertainty of researchers about the pathogenesis of AMD over the last century is reflected in its changing terminology. The evolution of this terminology is provided in a table to afford the reader a better insight into explanations proposed by researchers during this quest.
