Bietti's crystalline dystrophy (BCD), also called Bietti crystalline corneoretinal dystrophy, is a rare autosomal recessive eye disease named after Dr. G. B. Bietti. BCD is a rare disease and appears to be more common in people with Asian ancestry. ==Presentation== Symptoms of BCD include: * Crystals in the cornea (the clear covering of the eye) * Yellow, shiny deposits on the retina * 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. 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Bietti's crystalline dystrophy」の詳細全文を読む スポンサード リンク
