that's interesting, I've never heard of myopic CNV. I'll do a bit of googling. I did have an OCT though and fluorescin test at the opticians recently. And the floaters are not a sudden change, but a more gradual development over time. So I don't think they are likely to be an emergency, but it's interesting hearing about all the other potential causes. They're also quite different than the floaters that happened with the retinal tear.
Interesting that your PVDs were four years apart , @Tilllly - I've always read that they are usually within a couple of years, so was thinking my eyes were a bit odd that it's 10 years plus. Glad it's not just me.
I do have dry eyes, though I don't know if it's enough to be an actual syndrome. I use drops regularly, but it could well be related, and I'll keep using the drops and the mask etc.
Lots of issues with myopia that they don't really warn you about, although I guess they probably don't want to scare you. I know a lot of people with high myopia, but then I think it probably is more common in professions with lots of reading and so on. I thought at first that prescriptions greater than, e.g, -6 would be relatively uncommon, maybe 10 or 20% of people ,but actually I know loads.
