Glad to hear you're going to the neuro. There is a condition called amaurosis fugax that involves sudden but temporary partial or full loss of vision. It's due to blood clots...like an eye stroke.

Where was the numbness? Do these events last long?

Hopefully your neuro will order some labs for clotting factors as well as other tests. Continue to document any more occurrences. This information will be helpful to the doctor.

Good luck and keep us posted on the outcome.
