Reading time: 1 min

Optic neuritis is usually clinically diagnosed. This means that it is diagnosed by examining the patient.

Visual acuity, colour perception, the visual field, and eye and pupil movements are checked. 

Once the clinical diagnosis has been made, the following is requested:  

Magnetic Resonance Imaging or MRI machine

An imaging test, usually an MRI of the brain and optic nerves.

Syringe to perform serological testing and determine analytical parameters

It is also accompanied by an initial blood test to rule out infectious and autoimmune causes.

In some cases, other complementary tests are necessary to determine the cause, such as a spinal cord MRI or a lumbar puncture
