Altered colour vision: what diseases does it indicate?

By Cristiano Antonino On Jan 23, 2022

When it is not present from birth due to a congenital eyesight defect, impaired colour vision occurs when there is a sudden lesion in the optic pathways that may involve the optic nerve, macula, retina and choroid

Impaired colour vision: the disorder may affect only one eye (unilateral) or both eyes (bilateral)

The alteration can manifest itself in different ways, including a more or less marked fading of certain colours, particularly red, colour vision in shades of grey or otherwise less intense and sometimes accompanied by a progressive reduction in vision.

What diseases can be associated with impaired colour vision?

The diseases that can be associated with impaired colour vision are as follows:

Stroke
Optic neuritis
Retinitis pigmentosa
Retinoblastoma
Diabetic retinopathy
Corneal ulcer
Macular degeneration

Please note that this is not an exhaustive list and that it is always better to consult your doctor if the symptoms persist.

What are the remedies for impaired colour vision?

The disorder can only be treated after a direct diagnosis to identify the cause.

Drug therapy is generally used when there is an infection or inflammation of the optic pathways.

In all other cases, the main disease is treated, with impaired colour v. being a secondary symptom.

In these cases, therapy may be pharmacological, chemotherapeutic or surgical, depending on the case.

When should a doctor be consulted if colour vision is impaired?

If your colour vision is impaired, you should always seek medical attention as soon as possible because the symptom may be linked to a pathology, such as a stroke, for which rapid intervention is essential to ensure a better chance of recovery.
