Cone-rod dystrophy (CORD) is a group of inherited eye diseases that affect the retina and lead to vision loss.

The retina functions like film in a traditional camera, capturing images and sending them to the brain for interpretation. It consists of light-sensitive cells called cones and rods. Cones are responsible for sharp, detailed vision, particularly in daylight and for perceiving colour. Rods, on the other hand, are more effective in low light and are important for peripheral (side) vision.

In CORD, both cones and rods gradually lose their ability to function properly. Typically, cones are affected first, followed by rods.
