>Late stage detection of retinal diseases presents serious risks because eyesight become irreversible and incurable.
This is why people should get their eyes checked every year. especially if the are diabetic -- even if they think their vision is fine.
I thought my vision was fine. For fine print, I might need a pair of reading glasses; but, otherwise, I thought my vision was fine. One day, I saw what looked like a piece of lint on my left eye's eyelash. It turned out to be blood, more than a "floater."
My right eye just compensated, I had vision loss in my left eye. Thousands of laser zaps later and a vitrectomy, my left eye is stable; but, the vision loss is permanent. (Not to mention the "butt drug.") I was lucky. I can't really read with my left eye or do things requiring detailed vision; but, I can function.
This sounds like a great idea; but, the earlier you catch a problem, the better.
