The pupil region has a lower intensity than the rest of the image except for eyelashes.
I would suggest you use an appropriate threshold in the initial phase.
Then you can select the pupil based on the size of the objects in your binary image using regionprops using 'Area' -- the pupil will have the largest area here.
Hope this helps
