Optic Nerve Size Differences Related to Other Conditions?

[ibeadorkable]

I went to the eye dr. yesterday (she is an OD), who I had never seen before. I don't question her ability has a dr., as she did all of the same tests, etc. that I have had done at any other eye dr. I have ever seen.

She told me that my right optic nerve was bigger than my left. I have never heard that and have been having yearly eye exams since I was 10 (I am 26). My vision is worse in my right eye. I have trouble seeing distance.

I also have Meniere's Disease, unilaterally, and it happens to be on the right side. I received gentamician injections to try to treat that last November. That treatment comes with a whole bunch of side effects.

When I asked the dr. what it meant, having 2 different sized optic nerves, she didn't give me a straight answer. I was wondering a.) what it means and b.) could it someone be related to the Meniere's or the treatment?

I have searched the literature in the databases at my university and haven't been able to find an answer.
Thanks

Not related to Meiere's for sure

Optic nerve size can be determined by refractive error, pressure in eye, pressure in head, or it can be like feet or ears of different sizes and totally benign.

I would suggest you see an ophthalmologist. Find one near you at www.aao.org
