Optic Neuritis Learning Center
Tests could include:
 |
Color vision testing; MRI of the brain including special images of the optic nerve; Visual acuity testing; Visualization of the optic disc by indirect ophthalmoscopy;

|
The visual acuity test is used to determine the smallest letters a person can read on a standardized chart or card held 14 - 20 feet away.

 |
An eye examination is a series of tests that measure a person's ocular health and visual status, to detect abnormalities in the components of the visual system, and to determine how well the person can see.
|
 |
An eye examination is a series of tests performed by an ophthalmologist or an optometrist to determine if there are any pre-existing or potential problems with a patient's vision .
