The breaking down of the macula, the back portion of the retina that is responsible for clear vision. There are two main types of ARMD. (1) Involutional ARMD (Dry ARMD) results in a slow, progressive loss of central vision (usually not beyond 20/200), for which there is currently no treatment. (2) Exudative (Wet ARMD) results in distorted or blurred vision caused by the growth of the neovascular membrane in or near the macula. This maybe treated, if diagnosed early, without significant loss of central vision. (Ref: WebMD)
