Rod-cone dystrophy

Rod-cone dystophies are a group of eye conditions that affect the cells in your retina. The retina is at the back of your eye. It has photoreceptor cells called rods and cones. 

Rods help you to see things in your peripheral vision, i.e. the side of your vision. They are also responsible for helping you to see in darker lighting conditions.

Cones help you to see things in your central vision and are responsible for helping you to see in bright light conditions. They are also responsible for colour vision and small details.

The onset of symptoms you will experience will depend on the type and severity of your rod-cone dystrophy. This is linked to the particular gene that has affected your retina.

Common issues

Common symptoms that you can experience are:

  • Problems seeing small details.
  • Blurry vision, i.e. reduced acuity of vision.
  • Reduced colour vision.
  • Reduced contrast.
  • Issues with mobility due to poor peripheral or central vision.
  • Sensitivity to bright light conditions.
