| Phenotype details |
cone-rod dystrophy (HP:0000510); Maculopathy, characterized by a bull’s eye pattern or granular alterations of the macular RPE. Visual field testing usually shows (para)central scotomas. ERG recordings in CRD either show reduction or absence of cone responses in the presence of quantitatively less reduction in rod responses, or an equal impairment of both photoreceptor systems. Mild flecks at posterior pole. |
