Which of the following is NOT a differential of dry non-neovascular AMD?

Choroidal neovascularization (CNV) is a hallmark feature of wet, or neovascular, age-related macular degeneration (AMD). In this condition, new blood vessels grow beneath the retina and can lead to fluid leakage, resulting in vision loss. Dry AMD, on the other hand, is characterized by the gradual accumulation of drusen and retinal pigment epithelium (RPE) changes without the presence of CNV.

Therefore, since CNV is specifically linked to the neovascular form of AMD, it does not belong in the differential diagnosis for dry non-neovascular AMD. The other conditions mentioned, such as pigmentary abnormalities from central serous chorioretinopathy, pattern dystrophies affecting the RPE, and Doyne Honeycomb retinal dystrophy, all relate to variations in retinal pigment epithelium function or structure, which can mimic or coexist with dry AMD features, making them relevant differentials.
