Cone-rod dystrophies

Official Community

Cone-rod dystrophies (CRDs) are a group of inherited eye disorders that affect both the cone and rod cells of the retina (photosenstitive receptor cells). In contrast to rod-cone dystrophies, individuals experience deterioration of the cone cells more severely than the rod cells. Initial signs and symptoms typically include decreased visual acuity when looking straight ahead (central vision loss); loss of color perception; and an abnormal sensitivity to light (photophobia).
