Bietti crystalline corneoretinal dystrophy
MONDO:0008865Bietti's crystalline dystrophy (BCD) is a rare progressive autosomal recessive tapetoretinal degeneration disease, occurring in the third decade of life, characterized by small sparkling crystalline deposits in the posterior retina and corneal limbus in addition to sclerosis of the choroidal vessels and manifesting as nightblindness, decreased vision, paracentral scotoma, and, in the end stages of the disease, legal blindness.
Also known as: BCD, Bietti crystalline corneoretinal dystrophy, Bietti crystalline retinopathy, Bietti crystalline dystrophy, Bietti tapetoretinal Degeneration with marginal corneal dystrophy

One-Time gene injection aims to halt rare blindness
Disease control Not yet recruitingThis trial tests a single injection of a gene therapy called ZVS101e for people with Bietti crystalline dystrophy, a rare inherited eye disease that leads to progressive vision loss. The therapy uses a harmless virus to deliver a working copy of the CYP4V2 gene to cells in the ey…

Gene therapy takes on rare eye disease in Second-Eye trial
Disease control Not yet recruitingThis study is for people with Bietti's crystalline dystrophy, a rare genetic eye disease that causes vision loss. They have already received the gene therapy VGR-R01 in one eye. Now, researchers want to test if giving the same treatment to the other eye is safe and can improve vi…

New eye camera could spot retinal disease earlier
Knowledge-focused Not yet recruitingThis study will test a new, noninvasive camera called XyCAM CRE that measures blood flow in the back of the eye. Researchers will compare its images with standard eye tests in 350 adults with retinal disorders. The goal is to see if this camera can provide extra information to he…

Scientists track eye disease patterns to speed future cures
Knowledge-focused Not yet recruitingThis study looks back at medical records of 200 people with inherited retinal diseases, like retinitis pigmentosa and Stargardt disease. Researchers will analyze vision tests and eye scans to see how these diseases progress and how genetics affect symptoms. The goal is to find be…
