Fig. 8
An ultra-widefield fundus photograph and a fundus autofluorescence (FAF) image of a patient with Stargardt disease. An area of foveal atrophy shows decreased FAF. No characteristic flecks are evident on the photograph but easily recognizable areas of increased FAF were detected (arrows). A demarcation line is often observed in this disease as well as in retinitis pigmentosa and is considered to represent a closed optic fissure [71] (arrowhead)
