Vision problems caused by hypertension are not subtle, not intermittent, and not limited to a small blind spot.
Hypertensive eye damage, called hypertensive retinopathy, only develops after long term, consistently uncontrolled blood pressure, typically over years. It results from ongoing damage to the small blood vessels in the retina. In real life, this causes persistent and worsening visual changes, not something you notice occasionally. People develop steadily worsening blurry vision, distortion, and/or larger areas of vision loss. It does not come and go, and it does not present as a small blind spot you sometimes notice and sometimes do not. You would clearly and repeatedly/always notice a problem.
This does not occur with normal or well controlled blood pressure. Infrequent spikes, anxiety related elevations, or isolated high readings do not cause this kind of damage. The risk exists only when blood pressure stays high most or all of the time.
With true hypertensive vision damage, doctors always see clear abnormalities on eye exam before patients notice it. By the time vision is affected, blood pressure has been uncontrolled for a long period and readings are significantly elevated.
So the answer is it would not be just a blind spot, especially not one you occasionally notice. It would be progressive, persistent, and obvious. Infrequent high readings do not cause this. Only consistently elevated, untreated blood pressure over time does.
