Cone-rod dystrophy and cone dystrophy
Cone-rod dystrophy (CORD)
Cone dystrophy (COD)
Retinal cone dystrophy (RCD)
Macular dystrophy [DS:H01770]
Cone-rod dystrophy (CORD) and cone dystrophy (COD) are a subgroup of inherited retinal dystrophies characterized by progressive loss of photoreceptor function. In contrast to retinitis pigmentosa (RP), deterioration of the cone cells is more severe than the rod cells. In CORD, there is a progressive loss of cone photoreceptor function followed by gradual loss of rod photoreceptor function and retinal degeneration. In COD, cone function decreases progressively from its onset, though rod function is well preserved until the late stages of the disease.
