Er wait is retinal cancer a thing?

Yes. Like OP, I do a picture every year. Three years ago there was a scare, that turned out to be nothing.

Retinal imaging is used to detect damage from glaucoma or other eye disease, by "diffing" the fine blood vessels and nerves.

Yes. You can also have melanoma on your uvea

theres a ton of degeneative stuff too that's not strongly age corrilated.

Family history of glaucoma and macular degeneration. Also had a semi detached retina when I was a kid.

Yes, and it seems like its purposefully ignored in the "body scan" debate. full CT scans would be more problematic, and MRI's (especially no contrast ones) don't pick up a lot of things... but having annual comparisons over a few years would likely fill in some of those gaps. literally and figuratively.

Might be, but in the context it's also worth asking what better options you have for your health with that $1000.

(for some people that question may not apply, of course, but at a population level it does, and we have population-level questions about effective use of MRI time.). And if there's something better, you should spend it on that and then ask the question _again_. So it could be that getting a whole-body MRI is something like $30k down the list of best ways to spend money for improved health.

I'm not sure what the best use of $1k is from a health standpoint is, just noting that it's good to have a comparator.

Spending 1k on a gym membership and more fresh vegetables would be a pretty high return on investment, if one isn't in shape and eating healthy already.
