Hi!
I'm not sure if this would help or make it worse, but are you able to use a graphic organizer tool like, Inspiration. Here's a link to see an example.

If not, what about the Goodnotes app for ipad? I haven't used it extensively, but I wonder if you can scan a picture of the page, crop out what is distracting and place these pieces on their own pages.
Another idea for reading a "clean page" that's not too visually distracting. I use something that I call a word window. I take a half page of cardstock, cut a window in it the size of a line of text and or paragraph (or however big the are is you want to see) and put it over the page as the person reads. This blocks out the distractions that overwhelm the eye as you are reading.
Hope one of these give you an idea that works!
