MalaCards based summary : Bietti Crystalline Corneoretinal Dystrophy, also known as bietti crystalline dystrophy, is related to blepharocheilodontic syndrome and choroiditis, and has symptoms including progressive visual loss, abnormality of blood and blood-forming tissues and progressive night blindness. An important gene associated with Bietti Crystalline Corneoretinal Dystrophy is CYP4V2 (Cytochrome P450 Family 4 Subfamily V Member 2). The drugs Pyridoxal and Pyridoxine have been mentioned in the context of this disorder. Affiliated tissues include retina, eye and skin.

Genetics Home Reference : 25 Bietti crystalline dystrophy is a disorder in which numerous small, yellow or white crystal-like deposits of fatty (lipid) compounds accumulate in the light-sensitive tissue that lines the back of the eye (the retina). The deposits damage the retina, resulting in progressive vision loss.

NIH Rare Diseases : 50 bietti crystalline corneoretinal dystrophy is an inherited eye disease. symptoms 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 loss of visual acuity. bietti crystalline corneoretinal dystrophy is caused by mutations in the cyp4v2 gene and inherited in an autosomal recessive fashion.  last updated: 7/5/2011

UniProtKB/Swiss-Prot : 66 Bietti crystalline corneoretinal dystrophy: An autosomal recessive ocular disease characterized by retinal degeneration and marginal corneal dystrophy. Typical features include multiple glistening intraretinal crystals scattered over the fundus, a characteristic degeneration of the retina, and sclerosis of the choroidal vessels, ultimately resulting in progressive night blindness and constriction of the visual field. Most patients have similar crystals at the corneoscleral limbus. Patients develop decreased vision, nyctalopia, and paracentral scotomata between the 2nd and 4th decade of life. Later, they develop peripheral visual field loss and marked visual impairment, usually progressing to legal blindness by the 5th or 6th decade of life.
