High-Resolution Imaging of Patients with Bietti Crystalline Dystrophy with CYP4V2 Mutation
IR and AO images of BCD patients. Magnified IR ((a)–(c)), low ((d)–(f)), and high ((g)–(i)) magnification AO images from Case 1 ((a), (d), and (g)), Case 2 ((b), (e), and (h)), and Case 3 ((c), (f), and (i)) are shown. High-magnification AO images from a normal control are also shown (j). IR images are magnified images of Figures 5(a), 5(c), and 5(e). The red cross in IR images indicates fixation point. The crystals in the IR images are indicated by arrows ((a)–(c)). (a) and (d), (b) and (e), and (c) and (f) are images taken from exactly same region of Case 1, Case 2, and Case 3, respectively. In the low-magnification AO images, the locations of the clusters of hyperreflective signals correspond to the crystals in the IR images ((d)–(f), arrows). High-magnification AO images show that the clusters of hyperreflective signals are cone photoreceptor-like circular spots (Figure 6 red arrows). High-magnification AO image from normal control was obtained from 2-degree nasal of macular center. Bars indicate 100 μm.
