ABCA4 and Stargardt disease: The MFSD8-linked macular lesions mimic Stargardt disease and ABCA4-related COD and CORD: (i) two similar peaks of onset ages: late childhood [32,33] and late adulthood [34,35]; (ii) a typical foveal cavitation progressing to a collapse of outer retina and then to a bull’s eye macular lesion in early onset forms [36,37]; (iii) a subset of STGD1 patients had a cone or cone–rod pattern of retinal dysfunction at ffERG [38,39], as seen in patients in this series.
