What syndrome related to neovascular AMD is caused by a fungus endemic to Mississippi and Ohio river valleys?

The correct choice, which highlights the connection between neovascular age-related macular degeneration (AMD) and a specific syndrome, is Presumed ocular histoplasmosis syndrome. This syndrome is associated with the fungal infection caused by Histoplasma capsulatum, which is commonly found in the Mississippi and Ohio river valleys. The presence of this fungus can lead to the development of choroidal neovascularization (CNV), a condition where new blood vessels form beneath the retina, contributing to vision loss in individuals with AMD.

The association of this fungal infection with central serous chorioretinopathy and other retinal anomalies further underscores its significance in the context of AMD. Diagnosis often involves a combination of clinical findings and, in some cases, serological tests to confirm the presence of histoplasmosis.

Other options represent different conditions not specifically tied to this endemic fungus. For instance, Vogt-Koyanagi-Harada syndrome is an autoimmune disorder affecting the eyes and other systems, Behçet's disease is a systemic vasculitis that can impact ocular health, and Multiple evanescent white dot syndrome pertains to an idiopathic inflammatory condition affecting the retina but is not related to histoplasmosis. Understanding these distinctions is essential for recognizing how specific diseases can influence
