PILOT STUDY OF CHOROIDAL SYNPHLEBIA

Choroidal synphlebia represents a distinct choroidal venous phenotype characterized by fusion or coalescence of major veins with a lack of visible vessels in the overlying Sattler's layer and inner choroid. Alterations in the capacitance, resistance, and pressure distribution in the venous drainage system appear to be affected by synphlebia lesions. Recognition of synphlebia may provide insight into choroidal hemodynamics and may help explain atypical or treatment-resistant central serous chorioretinopathy and neovascular presentations.
