Which of the following conditions is NOT a differential diagnosis of neovascular AMD?

The correct answer indicates that pattern dystrophy is not a differential diagnosis of neovascular age-related macular degeneration (AMD). Neovascular AMD is characterized by the growth of new blood vessels in the choroid, which can lead to vision loss. The conditions that are considered differential diagnoses typically involve similar symptoms or findings, such as the presence of choroidal neovascularization.

Pattern dystrophy, while it can affect the retinal pigment epithelium and lead to visual changes, primarily involves inherited conditions that manifest as distinct patterns in the fundus and do not typically include the formation of new choroidal vessels associated with neovascularization. This differentiates it from conditions such as idiopathic choroidal neovascularization and choroidal melanoma, which are more directly associated with or can mimic the characteristics of neovascular AMD. PEHCR also presents features relating to neovascularization that require differentiation from AMD. Thus, when considering the diagnostic process, pattern dystrophy stands apart from the other conditions that can present similarly to neovascular AMD.
