I had a super headache for 10 days and the next day my vision was closing, it seemed to be underwater, I could see only in the center, I went to the ophthalmologist and I was told that some vessels had ruptured, and an edema had formed in the back of the eye. She gave me prednisolone eye drops every 6 hours and 10 mg tablets once a day. He referred me to the neurologist who, after examining me, urgently asked for an MRI. I'm very worried. What can it be?
Expert answer:

Many things can cause these symptoms, some things are serious and some not so much. He forgot to ask the neurologist the question and if he does not know, neither do I, anything I say would be just kicking; we hope that MRI can help.
