10 Optic Neuritis Symptoms
Reviewed: Dr. Mera
Symptom #6: Dyschromatopsia
Dyschromatopsia is defined as reduced or altered color vision. It occurs in almost if not all optic neuritis cases. Patients often describe it as a decrease in the vividness of colors especially shades of red. An Ishihara color chart can be used to evaluate the severity of reduced color vision.
Color testing is done separately in each eye to detect unilaterally affected cases. In optic neuritis, the severity of dyschromatopsia is far more than the loss of visual acuity. The reduced color vision is permanent.
