I had optic neuritis a year ago in my right eye, had full blood tests done and brain MRI which were all clear, the vision returned to normal within about 6 weeks, for about 4 weeks now my left eye has been blurry and its making me very nervous, however it is not as bad as last time as its only blurry (last time it was a black shadow).
I've been to an optician and they said my actual eyesight is fine, I've also been experiencing symptoms of tmj. I'm having blood tests tomorrow and i also have a vitamin b12 deficiency problem can u help I'm worried about Multiple Sclerosis.
Thanks for your Question
Multiple sclerosis can be manifested initially as Optic Neuritis which usually start in on eye.
In order to diagnose Multiple sclerosis as a cause of optic neuritis, MRI of the brain should be done in order to detect areas of demyelination.
The risk of developing Multiple Sclerosis in absence of demyelination in MRI is low, around 22% with in 10 years. MRI should be done annually for these patients who experienced optic neuritis with negative MRI.
You mentioned that you start to have blurred vision in your left eye. I advise you to have complete ocular examination which includes examination of the optic nerve because of such a previous history of optic neuritis in the right eye.
Treatment of optic neuritis with negative MRI is by observation unless the other eye has preexisting visual compromise.Using Intravenous Steroid in Negative MRI can be used also but it won't affect the final visual outcome, it only speeds up the recovery.
Optic neuropathy can be associated with Giant Cell Arteritis which can be manifested as Temporomandibular Joint Disorder(TMJ). You might discuss this issue with your doctor in order to run the required tests to rule out this disorder.
