Is reticular macular disease a choriocapillaris perfusion problem?

The etiology of reticular macular disease (RMD), a sub-phenotype of age-related macular degeneration (AMD), is controversial and has not been clarified. RMD is suspected to be a multifactorial, complex disease with genetic, environmental, and systemic factors playing an important role in its origin. Findings from combinations of different imaging modalities suggest that the pattern that characterizes this condition is associated with an alteration of the choriocapillaris blood flow. If the choroid is indeed affected in RMD, the possible linkage with inflammatory or other systemic diseases could be better supported.
