Cone Rod Dystrophy (CRD) is a genetic retinal disease that affects people both young and old. The genetic mutations passed down from parents to their children cause the retina cones and rods to degenerate, resulting in decreased sharpness in vision, increased sensitivity to light, impaired color ...

DYSTROPHYPurpose: To localize and identify the gene and mutations causing a cone rod dystrophy (CRD) in a consanguineous Tunisian family. Methods: We performed a clinical and molecular genetic study of a family with two individuals affected with CRD. DNA sample from the index patient was ...
Initial normal rod responses Cone responses are absent or more severely reduced than rod responses Reduced cone responses +, Present; −, absent; ACHM, achromatopsia; AD, autosomal dominant; AR, autosomal recessive; BCM, blue cone monochromatism; COD, cone dystrophy; CRD, cone-rod dystrophy;...
Whereas LCA is congenital or presents within the first few months of life, EOSRD is defined as a severe retinal dystrophy presenting before the age of 5 years. LCA/EOSRD is the most common inherited cause of severe visual impairment in children, accounting for 10–18% of children in ...
cone-rod dystrophy A form of retinitis pigmentosa in which central visual loss occurs first. Common symptoms include progressive visual loss followed by the loss of color perception, and eventually peripheral visual loss and night blindness. The visual loss is not correctable with standard lenses. Se...
Foremost, the electrophysiologic profile for PRD resembles rod-cone dystrophy rather than cone or cone-rod dystrophy. Annular visual field loss is complete in PRD and may be incomplete in PCD. In case 2, the previously unreported variant in GUCY2D, associated with autosomal dominant cone-rod ...
