@88lance I understand your dilemma of not finding answers to your vision condition. Ironically, I used to work for a researcher who studied vision processing abnormalities in the brain that was related to defects due to albinism. It makes sense that this is a brain processing phenomenon because you can see and the timing is off. I found another similar discussion, and then I found some research literature in the journal, Frontiers in Human Neuroscience published in 2013. This sounds like what you are describing. Here is the link:

-A world unglued: simultanagnosia as a spatial restriction of attention
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3627977/
There are several co-authors around the world, but one of them is at the Department of Psychological and Brain Sciences, Dartmouth College in New Hampshire. If you click the link for the authors, you can find contact information. I hope that could lead you to researchers who may be studying this. It seems like this may not be widely known in medical practice.

Here is the other similar discussion that may be interesting to read:

I am also an artist, and I was wondering if you would be able to train yourself to have a more complete field of vision. One of the exercises that I did in art school in life drawing class was a 3 minute pose with a live model on the stand. That forces you to look at details and compare while getting a loose sketch, and you have to keep looking back and forth between the model and your drawing very quickly to compare to see how accurate the drawing is. This isn't an easy task, but it gets easier as your eye gets more accurate in judging your drawing. Perhaps rapid eye movements will force your brain to recognize the bigger picture. I think it may be an interesting experiment to see if taking a drawing class may help.

You can also get a sketch book and sketch, but you won't have the time limit forcing you to look quickly, so I think a class would be better. Don't worry about trying to make masterpieces. Most people in classes are not professional artists, and your purpose is simply to try to improve your vision. If this helps, then you have something to report to the researchers who study this. You don't need expensive supplies. I did this in art school with a newsprint pad and grease pencil. We were trained to hold our pencil out at arms length and make large strokes. You can also use a ball point pen or regular pencil and office paper.

Sometimes it just takes time to figure out health problems, maybe years until there is another clue, and doing your own drawing experiment might speed up the processing time for your vision. I would be very excited if that works! The other thing that may help is to ask one of your doctors what supplements can help vision. The retina does a lot of maintenance to keep the rods and cones working. This is kind of like the processor chip in a digital camera that gathers the image. Protecting your eyes from UV light with blue blocking sunglasses is probably a good idea because the UV light can contribute to cataracts. Turning down the intensity of a computer screen may help too because of the blue light from the screen and eyes fatigue.

What are your thoughts? Are you ready to start drawing?
