Which is the most common form of AMD?

The most common form of age-related macular degeneration (AMD) is dry AMD. This form is characterized by the gradual accumulation of drusen, which are small deposits that can form under the retina and lead to the degeneration of retinal pigment epithelium and photoreceptors. Dry AMD typically progresses slowly, and the vision loss associated with it can be gradual, making it more prevalent among the population diagnosed with AMD.

In contrast, wet AMD, while it can lead to more acute and severe vision loss due to the presence of choroidal neovascularization, accounts for a smaller proportion of AMD cases. The other forms such as advanced AMD and early AMD represent stages of the disease rather than specific types. Therefore, dry AMD is more commonly diagnosed and is a significant concern in the aging population due to its higher incidence, making it the correct choice.
