Understanding the Difference Between Dry and Wet Age-Related Macular Degeneration
Originally Published by Retina Associates, LLC.
Age-related macular degeneration (AMD) is an eye disease that can blur your central vision. It occurs when aging causes damage to the macula, a part of the retina that controls sharp-straight-ahead vision. There are two types of AMD: dry and wet. Here’s what you need to know about the differences between these two types of AMD, as well as available treatment methods and how to seek help from a retina specialist.
Dry AMD
According to the National Eye Institute (NEI), about 90% of patients with AMD have the dry type. In dry AMD, layers of the macula get progressively thinner, functioning less and less. Little piles of waste product from the cells of the eye, called drusen, appear on the retina and are only visible during an eye exam. For the most part, dry AMD doesn’t progress further than pigment discoloration and the presence of drusen. However, advanced cases of AMD are called geographic atrophy. In this instance, large sections of the retina stop functioning.
Wet AMD
Wet AMD is a condition where new blood vessels grow in the choroid layer behind the retina. These new vessels are weak and can leak blood and other fluid into the eye, causing scar tissue to form. Wet AMD is more serious than dry AMD and can lead to permanent vision loss. Treatments can help slow the progression of the disease, but once vision is lost, it can’t be restored.
