Cone-Rod dystrophy


This is an inherited disease that, over time, causes deterioration of the specialized light-sensitive cells of the retina. People with cone-rod dystrophy typically experience decreased sharpness of vision followed by a loss of peripheral vision and color perception. The most common form of cone-rod dystrophy is Retinitis Pigmentosa. There is no treatment or cure for this disease, which is also referred to as cone-rod degeneration, progressive cone-rod dystrophy, and retinal cone dystrophy.  Reference:

As a group of inherited retinal diseases, the cone and cone-rod dystrophies have many similarities to the Retinitis Pigmentosa (RP) group of conditions. They can also be inherited as autosomal recessive, autosomal dominant and X-linked disorders. Currently, more than 20 faulty genes have been identified as causing cone and/or cone-rod dystrophies. Several of these genes also cause RP – sometimes RP and cone-rod dystrophy can coexist in a single family. Reference:

Currently there is no treatment for Cone-Rod Dystrophy.  However, low vision aids are useful in early stages and later when vision becomes worse, mobility training can be of immense help.

Some research related to Macular Degeneration or Retinitis Pigmentosa may be applicable to Cone-Rod Dystrophy.

Support groups bring together people facing similar issues. Members of support groups often share experiences and advice. It can be helpful just getting to talk with other people who are in the same boat.
