Multiple Sclerosis

It is important to remember that MS is only one part of a person and not the person.

MS does not represent them, it is not their identity, they are as normal as the next person.

Optic Neuritis                                                                                                                                                                                              

Up to 50% of people with MS will develop an episode of optic neuritis while 20% of the time optic neuritis is the presenting sign of MS .

 

The presence of demyelinating white matter lesions on brain MRI at the time of presentation of optic neuritis is the strongest predictor for developing clinically definite MS. Almost half of the people with optic neuritis have white matter lesions consistent with multiple sclerosis.

 

At five years follow-up, the overall risk of developing MS is 30%, with or without MRI lesions.

 

16% of people with a normal MRI still develop MS but at a lower rate compared to 51% of people with three or more MRI lesions.

 

44% of people with any demyelinating lesions on MRI at presentation will not have developed MS ten years later

 

Optic Neuritis (ON) most often includes pain, with eye movement, in or behind the eye when vision deteriorates. ON episodes often reappear, each reaching a peak within days, and recovery takes from 5 weeks to six months - with or without any particular treatment. [1]

 

An ON attack is often an invisible event, symptoms are either not noticed, or simply dismissed.

 

Subsequent Visual Evoked Potential (VEP) testing always registers prior damage, as slowed response times. This finding can be used to fulfil MS's diagnostic requirement of a previous attack.

 

Optic Neuritis is very common in many, but not all and usually occurs in only one eye at a time. It is one of the first diagnosable signs that you may have Multiple Sclerosis.

 

When inflammation involves the first part of the nerve and can be seen at the optic disk, usually during the course of an eye examination, it is known as Optic Papillitis. This may cause colours to appear washed-out or faded and bright lights generally make seeing difficult, even when there are good colour contrasts.

 

 

Wearing yellow tinted sunglasses or adding a light photo-ray tint to your eyeglass prescription, greatly reduces the glare of bright lights.
