Cone rod dystrophies (CRDs) are inherited retinal dystrophies that belong to the group of pigmentary retinopathies. CRDs are characterised by retinal pigment deposits, visible on fundus examination, predominantly localised to the macular region. CRD is characterised by primary cone involvement or, sometimes, by concomitant loss of both cones and rods, explaining the predominant symptoms of CRDs: decreased visual acuity, colour vision defects, photoaversion and decreased sensitivity in the central visual field, later followed by progressive loss in peripheral vision and night blindness.
