What happens if a detached retina goes untreated?
If you’re sure that it’s a detached retina the eye doctor will have already told you what happens when you don’t treat it. You will go blind. Why would anyone knowing this not get treated and be able to see out of the eye again? Maybe it’s against your religion, but that would be about the only good reason. Detached means just that. I hope that if this person is you that you get treated for it or maybe you were just curious. I hope this answers your question.
