Comments Bietti crystalline corneoretinal dystrophy (BCD) is an autosomal recessive retinal dystrophy first described by Bietti in 1937.3 Numerous tiny glistening yellow-white crystals in the posterior pole with RPE atrophy and hypertrophy along with choroidal sclerosis characterize the disorder.2 About half the cases have similar crystals in the superficial peripheral cornea.4 The disorder has pigmentary
