I had an right temporal choroid plexus AVM, due to surgical complications I underwent gamma knife radio surgery last year. And asked to follow up every six months, six months ago there was improvement in shrink of AVM but there was proliferation. Doctor asked to come after six months with MRI. Yesterday in MRI report it was mentioned that there was still proliferation. And within six months my eye myopia has increased. Does proliferation affect my vision. I am currently on levipil 500 mg. Please help.
