Bietti's crystalline dystrophy (BCD), also called Bietti's crystalline retinopathy, is a rare autosomal recessive eye disease named for Dr. G. B. Bietti.[1]
BCD is a rare disease and appears to be more common in people with Asian ancestry.
Presentation
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.
