There is a connection to low B12 and optic nerve problems...
Undiagnosed low B12 can lead to blindness and neuritis.
High homocysteine levels indicate a possible low B12 level along with issues with folate, and B6. High homocysteine causes irritation to the blood vessel lining and hence can cause clots in the retina or optic nerve.
People with the mutation in methylation called MTHFR may develop high homocysteine because the B12 and folic acid in the diet cannot be methylated (activated to is biological useful forms). There is a DNA test you can ask for to see if you have this genetic problem.

You can become low in B12 (the new low in testing today is
400pg/ml), if you are vegan, use acid blocking drugs long term,
have pernicious anemia, or low stomach acid for other causes (aging is one).
So if you haven't investigated these factors, I think you should.

I just suffered a stroke on my right optic nerve on May 15, 2016. In 12 days, I lost my vision on my right eye. I went from seeing an ophthalmologist, to a retina specialist, to a neuro-ophthalmologist (a neurologist just for the eye). This latest specialist was the one who diagnosed me with "Ischemic Optic Neuropathy", or stroke on my optic nerve. I went through numerous tests: two MRI's to rule out MS, blood count test, clotting of the blood, ultrasound of the carotid arteries, Lyme disease, even a biopsy to rule out "Temporal Arteritis". I also took 60 mg. of oral steroids, and when that didn't work, I was admitted to the hospital for intravenous steroids (1,000 mg. a day for three days), but this didn't even touch the swelling of the optic nerve. In fact, while in the hospital, my vision got worse. Furthermore, ALL of the tests came back negative or normal. As it turns out, doctors are stunned. They do not know why I got this. My ophthalmologist said that it could be that I have very tiny blood vessels in the eye, and the smallest clot can get caught. I am now taking a baby aspirin a day. There is another possibility, which I think it is the culprit of my problem. I've taken Lanoxin/Digoxin .25 mg., which was consider a very safe drug for the past 30 years, to control a heart condition called "Supraventricular Tachycardia". Now, 30 years later, my husband found on the Internet that it can cause issues on the optic nerve and cataracts. I am a healthy 56-year old woman, who exercises often and eats right. I never would have thought that I would have vision problems at this 56. This has been a very tough and trying time for me. Tomorrow, it will be one month since I woke up with a blurry vision in the corner of my right eye. Now, I'm facing the fact that I have to get used to seeing the world with one eye. I'm heart broken. I have my 'O.K.' days, and days when I cry and feel sorry for myself. This is the hardest thing that I've ever had to endure. Any words of encouragement will be greatly appreciate it. I really need them!! Thank you.
