Ocular migraine or TIA?
I experienced a strange vision disturbance yesterday that lasted about 10 minutes. I was looking at my phone and suddenly random letters and words were smudged out. Like someone erased them here and there. In those spots it looked kind of shimmery, like an oil on water effect. I went to the ER and got blood work, CT scan, and EKG - all normal. Diagnosed with transient ischemic attack and waiting for follow ups (MRI and echocardiogram). l understand there can be overlap between TIA and migraine symptoms. The ER seemed dismissive of it being a migraine because of how quickly it came on and resolved. Also I had a mild concussion 3 weeks ago (feel fine now) but that obviously could be factor.
Anyone out there have similar vision issues with ocular migraines? The blotting out of letters was so odd and disconcerting.
