Cone dystrophy is an inherited eye disease that destroys specialized cells in the retina, the light sensitive tissue that transmits light from the eye to the brain via the optic nerve. Cone cells provide sharp visual acuity and also allow us to perceive color.
Patients with cone dystrophy usually show symptoms by age 20 with reduced central vision and poor color vision. Patients may also have nystagmus and be sensitive to light. Later, patients experience night blindness and loss of peripheral vision. At this time, there is no treatment for cone dystrophy.
Currently, the NEI does not have a factsheet on this condition.
