Overview
A Föster-Fuchs spot is a pigmented scar of regressed myopic CNV.
On Fundus photos, Förster-Fuchs spots appear as raised, round pigmented lesions of RPE proliferation adjacent to areas of chorioretinal atrophy consistent with regressed choroidal neovascularization.
OCT typically shows RPE hyperplasia with adjacent chorioretinal atrophy and a distinct increase in light transmission through this area.
Fundus autofluorescence imaging often shows a focal area of hypoautofluorescence due to signal blockage from the RPE hyperplasia and chorioretinal atrophy
