eyeball segmentation in MRI images

Does anyone have a tool for segmenting/masking the eyeball in MRI images? Specifically proton density or T2-weighted images.

What came up when you tried using your favorite internet search engine? I would think many segmentation tools would be able to segment the eye, so I don't think you need to make your search so narrow.

Maybe other people will post a link to some general method. If you want more specific help, provide example images (make sure it is legal for you to share them and that they are properly anonymized)

The answer might look something like this brain MRI image on Wikipedia:

Except the image intensity might be flatter across the brain and eyes. In this particular image the eyes appear quite bright. I tried using the spherical Hough transform to detect sphere across multiple image slices, but it doesn't seem to be working reliably across multiple image datasets.
