Left occipital ischemic stroke has completely blinded my right field of vision. Inexplicably, my left field is also severely impaired.
ABOUT THIS CASE FILE
Following a left ischemic occipital stroke in March 2019, I have lost all sight in my right visual field. An MRI showed damage that can explain this. However, my left field of vision is also impaired - it is streaked not unlike migraine auras I have experienced in the past although those lasted only for short intervals. The left field impairment is not explained by anything showing in the MRI. I have seen a neurologist and a neuro-ophthalmologist who can't explain the left field vision impairment.
I have a history of migraines with auras, but I don’t know if this has any bearing on my current visual impairment. I have had a constant headache since the stroke, but it does not have the characteristics I associate with migraines. The intensity of the headache varies, with the lowest rating a 3, and the highest around a 7. (To me, 8 is complete inability to function, 9 is ER territory...)
The stroke itself was very unexpected because I am 48 years old, I do not have high blood pressure, I have never smoked, I rarely drink alcohol, and while somewhat overweight - 187 lbs / 5'6" tall -- I'm certainly not morbidly obese.
A possible cause of the stroke is a PFO found by my cardiologist. The cardiologist and neurologist agree that the PFO needs to be repaired, so I will soon be undergoing a procedure to "patch the hole."
I don't know if any of these factors are connected to my left field vision impairment. I only know that I am struggling to function in my daily life, knowing that I should be able to see the left visual field, but that for some reason, that portion of my vision is also impaired. As a result, I am unable to read well, perform my job accurately (largely due to the reading problems), find my way around outside, walk without falling over obstacles I should be able to see, and visually recognize people I know well.
I desperately want to understand what is happening and how to get on with my life.
