Do me a favor some time and try to read through the scotoma, if you remember to. I think that I would have just assumed I couldn't do it if I hadn't been reading something really interesting when the scotoma started. It's only because it came on while I was already reading that I discovered that I was able to continue.

If you remember to try it, the results will be interesting no matter which way they turn out.

I have migraine once or twice a year, and the most recent attack indeed interrupted my reading, quite simply did not see the letters through the zigzag. As it gradually covered the focal point of my vision I was trying to "squint" mentally but eventually gave up. There was no followup headache, just a slight vertigo.

Interesting data point. I just have the one experience to report, so far, but I fully intend to test it out again the next time I have an episode.

Not the GP, but I've tried to read through mine before but I've also focused my vision on the edges where the scotoma hasn't reached. I'll try to go "through" it next time...

Yes this seems very worthwhile to try. It seems like a research topic to me.
