Figure 1.

Fundus photographs, infrared images, and fundus autofluorescence images of eyes with Bietti crystalline dystrophy (BCD) with CYP4V2 mutation. Images from Case  1 ((a)–(f)), Case  2 ((g)–(l)), and Case  3 ((m)–(r)) are shown. Fundus photographs ((a), (d), (g), (j), (m), and (p)), infrared images ((b), (e), (h), (k), (n), and (q)), and fundus autofluorescence images ((c), (f), (i), (l), (o), and (r)) are shown. Fundus photographs of the patients show many small glistening yellowish white spots. Infrared image shows the crystalline deposits clearly. Fundus autofluorescence images show patchy hypofluorescent areas located throughout the degenerative lesion. The crystals observed in the IR images are located only in the areas between the hypofluorescent FAF lesions.
