Dry AMD is characterized by which of the following?

Dry AMD is characterized by which of the following?

• A. Increased intraocular pressure
• B. Dry AMD causes drusen above Bruch's membrane, and it is more common but has a slower progression
• C. Wet AMD affects the macula
• D. Drusen below Bruch's membrane

Answer: (B)

Dry AMD is the non-neovascular form of age-related macular degeneration, distinguished by drusen depositing between the retinal pigment epithelium (RPE) and Bruch's membrane. This location places drusen on the side of the retina closest to the RPE, i.e., above Bruch's membrane. This form is more common than the wet type and typically progresses more slowly, though it can lead to geographic atrophy of the RPE and overlying photoreceptors, affecting central vision. In contrast, increased intraocular pressure points to glaucoma, and the wet form involves choroidal neovascularization and usually progresses more rapidly. Drusen located below Bruch's membrane are not characteristic of AMD.
