What are the types of ARMD?
The “dry” form of ARMD refers to the atrophic form which is characterized, in its late stages, by the degeneration (i.e. atrophy) of the retina in a region that includes the macula. “Dry” ARMD develops and progresses slowly over a period of 5-10 years or longer. Appoximately 85% of the total ARMD patient population has this atrophic form. The less prevalent, “wet” type of ARMD is also referred to as neovascular or exudative ARMD. It is characterized by the ingrowth of new blood vessels from the choroid. “Wet” ARMD progresses much more rapidly, over a period of weeks or months, and usually results in legal blindness in the central portion of the visual field.
