I don't know that anyone has ever really looked at it. It is hard to define the volume for it as it is just the crossing point of the optic nerves.

Dear FreeSurfer experts,

I am examining the optic chiasm segmentation in FreeSurfer. How reliable is the volume measurement of the optic chiasm when using FreeSurfer?

Best regards
