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.

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

Yes. You can also have melanoma on your uvea

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