title: Focal choroidal calcification.
abstract: Localized choroidal calcification was detected clinically in two otherwise healthy men. The lesions showed typical features of choroidal nevi. One patient exhibited features suggesting a drusen overlying the nevus. Echography detected choroidal calcification in both cases. A-scan echography revealed a highly reflective choroidal mass attenuating the ultrasound beam. B-scan ultrasonography revealed a dense choroidal mass attenuating the ultrasound beam with focal echoes remaining at low sensitivity. Orbital radiographic and CT scan examination confirmed the echographic findings.
