cone-rod dystrophy (CORD)
inherited retinal dystrophies belonging to the group of pigmentary retinopathies
Pathology:
- retinal pigment deposits visible on fundus examination, predominantly in the macular region
- initial loss of cone photoreceptors followed by rod degeneration
Genetics:
- X-linked cone-rod dystrophy
- dominant cone-rod dystrophy
Clinical manifestations:
- decreased visual acuity & sensitivity in the central visual field, followed by loss of peripheral vision
- severe loss of vision occurs earlier than in retinitis pigmentosa
