• Should I be concerned about having an optic nerve sheath?


    Question:

    Around seven years ago, when I was 14, I went to an ophthalmologist and while there, she told me that I had a sheath covering a nerve of my left eye. She told me that I was born with it, and I left it at that. But searching online I found many pages about “nerve sheath tumors.” Ever since then, I've been freaking out to the point of crying. Do I have a reason to be concerned?


    Answer:

    While it is difficult to be certain what your ophthalmologist is referencing, you most likely have myelinated optic nerve fibers. This is a benign (harmless) condition that should not be of concern. However, to be sure, it would be best for you to visit an ophthalmologist and be reexamined.
