Bietti's crystalline dystrophy (BCD), also called Bietti's crystalline retinopathy, is a rare autosomal recessive eye disease named for Dr. G. B. Bietti.
BCD is a rare disease and appears to be more common in people with Asian ancestry.
The symptoms of BCD include: crystals in the cornea (the clear covering of the eye); yellow, shiny deposits on the retina; and progressive atrophy of the retina, choriocapillaries and choroid (the back layers of the eye). This tends to lead to progressive night blindness and visual field constriction.
It has been associated with CYP4V2.
