What is wet age-related macular degeneration (wAMD)?

wAMD is one of 2 forms of age-related macular degeneration (AMD), an eye disease that mostly affects people over the age of 50. In people with AMD, the central vision is gradually destroyed. This central vision is needed to see things clearly. With impaired central vision, tasks like recognizing faces, reading and driving a car are difficult or impossible. AMD does not cause pain.

AMD affects a portion of the retina at the back of the eye called the macula. The macula is a light-sensitive tissue needed to see fine details. The 2 forms of AMD, wet and dry, both affect the macula.

wAMD, also called age-related neovascular macular degeneration, is the most severe form of the disease. In wAMD, abnormal blood vessels begin to grow beneath the macula and leak blood and fluid. This leakage can lead to scarring and permanent visual impairment in weeks or months.

The good news is that, with early diagnosis and treatment, people with wAMD may be able to slow down the progression of vision loss and improve vision.
