Hello,
Thank you for posting your query at DoctorSpring.com
I have noted the detailed description of your symptoms. it was helpful in understanding the problem.
I would agree with your ophthalmologist that the most important condition is to exclude a small blood clot entering the ophthalmic artery (a branch of carotid artery). This condition is technically referred to as TIA- transient ischemic attack. So, the evaluation should include MRI and MR angiogram of brain, along with doppler ultrasound of carotid arteries. I have noted that you had a normal MRI in 2013.
In view of PFO, it may be important to discuss this (possible TIAs) with cardiologist and plan for PFO closure. There are now easy ways of closing PFO.
Ocular migraine is a second possibility. If all the above tests are normal, then, migraine should be considered. In that case, preventive medications may be needed.
I hope it helps.

Hi Doctor,
Thank you for your response. Can I ask though, what makes you feel that this is more of a blood clot/stroke issue over a migraine? Also, if I got an MRI what would you expect it to show? Assuming that if I had had a blood clot that it would be gone by now. Would the MRI show anything that would help diagnose this problem?
I believe that a TIA can only be seen in an MRI only after the first 24 hours of the incident. Is this correct?
Thank you,
Natalie
Thank you for getting back.
In migraine, headache is commonly seen after visual disturbances. Absence of headache is less common. So, it is the second possibility here.
In MRI, we can see evidence of small clots in about 50% cases, similar to yours. In TIAs too, about 50% of MRI show small blood clots, as early as two hours after the incident.

So basically, this happened now well over 48 hours ago so an MRI of the brain will most likely not show anything. Right? At 23 years old could I really be at risk for stroke or blood clotting? I do have a small head, could this cause me to have carotid artery issues?
I spoke with my neurologist over the phone who is a senior neurologist and the head of internal medicine at a well known hospital and she told me that she was very confident that what I had was a retinal migraine and that these tests are not necessary to do. She isnt concerened as my Opthamologist was. She said that I had pressure (like feeling in high altitude) around my right ear at the time of blindness in the right eye which could signify that it was a migraine. What do you think of this? You are both neurologists and have conflicting opinions. My neurologist said that if I did have a stroke I would not have regained vision in the right eye.
I also have normally low blood pressure around 100/60 that has been read at 80/40 before going to bed.
Since I am not covered by insurance until March 1st I need to know if I should wait until March 1st to see a specialist or if you feel it is urgent and that I should go to the hospital (where I am covered) to get tests?
Thank you for getting back.
As I discussed earlier, there remains two possibilities- minor stroke and retinal migraine.
At your young age, you have an increased risk of stroke because of PFO.
Small head size does not increase the risk of stroke or carotid artery disease.
MRI and MRA should be done sooner or later. It is not urgent. You can wait until March to see a specialist and do MRI.

Hi,
I have another concern. Recently I've been having constant "off-balanced" dizziness when I walk around. I feel fine when I am sitting. But I've had some nausea too. But yesterday I was singing and I was snapping my fingers iwth my right hand and all of a sudden I lost motor control of my right hand and following that my whole arm went completely numb. I did have some pain in my head but nothing severe. When my right arm went numb I panicked. I must add that I was doing arm exercises like drop push ups earlier. I called my neurologist today but never heard back. when I saw the neurologist they told me that I do not need an MRI and she believes that my problems are linked to migraines and low blood pressure. My boyfriend who I live with felt that It had something to do with my exercises and said I shouldnt worry. I have had numbness before but it hasnt happened for a while. Today I've felt numby all over my body (arms and legs) and I dont know if its from nerves or what. What should I do?
Thank you for getting back.
Transient weakness or numbness of arm could indicate TIA- transient ischemic attack, also known as minor brain stroke.
Please see a neurologist for confirmation, as soon as possible.
Exercise would not lead to similar symptoms.
