 Cone-rod dystrophy encompasses a cluster of eye conditions characterized by progressive vision loss that exacerbates over time. These ailments primarily affect the retina, the light-sensitive layer at the eye's rear. In individuals with cone-rod dystrophy, the gradual deterioration of the retinal light-sensing cells precipitates vision impairment. The cone cells are initially affected, manifesting symptoms such as compromised vision clarity, color vision issues, and heightened light sensitivity. Subsequently, there's a progressive decline in rod cells, resulting in night blindness and peripheral vision loss. The onset of cone-rod dystrophy typically occurs during childhood, with early indications including diminished visual acuity and heightened light sensitivity. The most prevalent cause of autosomal recessive cone-rod dystrophy is mutations in the ABCA4 gene, which account for 30 to 60 percent of cases. Meanwhile, at least 10 genes are linked to the autosomal dominant inheri...

 Cone-rod dystrophy is a group of related eye disorders that causes vision loss, which becomes more severe over time. These disorders affect the retina, which is the layer of light-sensitive tissue at the back of the eye. In people with cone-rod dystrophy, vision loss occurs as the light-sensing cells of the retina gradually deteriorate. The cone cells are initially involved, as previously mentioned, and difficulty with the clarity of vision, color vision problems, and light sensitivity can be some of the earliest symptoms experienced. This is followed by a progressive loss of rod cells, which leads to night blindness and loss of side vision. The first signs and symptoms of cone-rod dystrophy, which often occur in childhood, are usually decreased sharpness of vision (visual acuity) and increased sensitivity to light (photophobia). Mutations in the ABCA4 gene are the most common cause of autosomal recessive cone-rod dystrophy, accounting for 30 to 60 percent of cases. At least 10 ge...
