Fundus fluorescein angiography (FFA) in XLRS shows no leakage. FFA in DCMD shows leakage of variable degree depending on the stage of the disease. Our case [Fig. 6 of publication] shows leakage albeit faint which can be appreciated in higher magnification. Fundus autofluorescence imaging in our case shows multispot hyperautofluorescence in fovea which can also be seen in XLRS. However, in addition to this, we find a broader area of hyperautofluorescence [Figs. 3 and 4 of publication] suggestive of diffuse retinal pigment epithelial dysfunction. This pattern of hyperautofluorescence is not seen in XLRS, which is predominantly an inner retinal disease to start with. These findings point more toward DCMD.[4,5]
