Confused about staphylomas

I am a bit confused about staphylomas. I have read that something like 80-90% of high myopes have a staphyloma of some sort and I have also read that, by the age of 60, 50% of people with staphylomas in both eyes will be legally blind. This seems like an incredibly high percentage and seems to suggest that 50% of highly myopic people will be blind by the age of 60. Does anyone know if this is true or have I somehow misread something? Could someone also please explain what it is about staphylomas that causes blindness as I can't find much about it on the internet. Do staphylomas result in complete blindness or partial loss of central vision? Thank you

Your information is wrong. If you don't have a staphyloma now at age 60 you won't get one. The % of myopes that have staphyloma is not nearly that high,  in those that do they do not cause complete blindness.

Sorry I forgot to mention that I am only 28. I had just read that of those that do have a staphyloma half will be legally blind by the age of 60. Is it because staphylomas can cause retinal detachments that means they can cause partial blindness or is it because of some other mechanism?

Re-read what I said. Your information is wrong. See a retina Eye MD and discuss this after examining your eye. You should be reassured.
