| Disease ID | Source | Name | Description |
| 300476 | OMIM | Cone-rod dystrophy, X-linked 3 (CORDX3) | An inherited retinal dystrophy characterized by retinal pigment deposits visible on fundus examination, predominantly in the macular region, and initial loss of cone photoreceptors followed by rod degeneration. This leads to decreased visual acuity and sensitivity in the central visual field, followed by loss of peripheral vision. Severe loss of vision occurs earlier than in retinitis pigmentosa, due to cone photoreceptors degenerating at a higher rate than rod photoreceptors. The disease is caused by variants affecting the gene represented in this entry. |
| 300071 | OMIM | Night blindness, congenital stationary, 2A (CSNB2A) | A non-progressive retinal disorder characterized by impaired night vision, often associated with nystagmus and myopia. The disease is caused by variants affecting the gene represented in this entry. |
| 300600 | OMIM | Aaland island eye disease (AIED) | A retinal disease characterized by a combination of fundus hypopigmentation, decreased visual acuity due to foveal hypoplasia, nystagmus, astigmatism, protan color vision defect, myopia, and defective dark adaptation. Except for progression of axial myopia, the disease can be considered to be a stationary condition. Electroretinography reveals abnormalities in both photopic and scotopic functions. The disease is caused by variants affecting the gene represented in this entry. |
