Perhaps you have read about my experience 7 months ago. I had a 2.7 mm. meningioma that was 1/16 th of an inch from my optic nerve. The neurologist that I first consulted when the meningioma was found incidentally during a scan for something else referred me to a radiation oncologist as I was told it was too close to my optic nerve to do surgery. The radiation oncologist agreed. My daughter insisted I go to UCSF and talk to a neurosurgeon.
He said, "No problem, I do one or two a week." (specifically that close to the optic nerve)
The surgery was successful; the entire meningioma was removed.
The surgery was much easier than I had ever imagined. I was home on the third day. Except for the pain med given during surgery, I only took tylenol. One drawback was that I did have double vision for 3 1/2 months after my surgery. But, that resolved and I am doing well. I might add that it is imperative that you receive care at a top notch neurosurgical center.
