You could use the in built Viola Jones detector in Matlab using the option 'Single Eye' or 'Eye Pair' options.

By using that only I found out the Bounding box for all the facial features.But how to find the corners??

You might need to perform upper and lower eyelid segmentation. I would recommend having a look at the paper by Daugman. http://www.cl.cam.ac.uk/~jgd1000/irisrecog.pdf
