Well, guess this is the right page for this then....
Sister was having some vision issues few months back, chalked it up to older age and parents with poor vision. Got eye glasses for the first time in her life and though that helped some, she was still having problems with her left eye. One good thing about my sister is she is persistent as hell and so she continued to tell her doctors something wasn't quite right and so the squeaky wheel got an MRI recently, tests came back and she's got a 7mm brain aneurysm (look who can spell THIS one right!) compressing her left optic nerve, hence the vision issues.
Squeaky goes in for surgery tomorrow at 10am. Going in through her leg artery, travelling up to put a sleeve or something to cap off the aneurysm. I think this sounds a lot worse than it is, but nothing like capping 2018 off with some brain surgery for your only sibling.
Neat year.
