I guess what Dishant is trying to say is that for those of us not familiar with this domain, another image pointing out the region you want to extract (manually delineated) will help. I cannot be sure what part of the above image is the optic disk or the optic head nerve.

This is what I'd try, assuming all you have to work with is the binary image.
- do a hole fill
- subtract the original binary image
- filter out blobs that don't meet size and circularity and solidity criteria.
Of course it might be better if you started with the original color image and used some of the published methods in section 20.5 here: http://iris.usc.edu/Vision-Notes/bibliography/contentsmedical.html#Medical%20Applications,%20CAT,%20MRI,%20Ultrasound,%20Heart%20Models,%20Brain%20Models

@ Image Analyst I have done "retinal blood vessels segmentation". However, segmentation result is not so good. Below is attached the image having manual segmentation obtained from Drive database and segmentation of same imageusing my code.
I have done segmentation using following papers. http://manzaramesh.in/Publication/05-10-2013/Retinal%20blood%20vessels%20extraction%20using%202D%20median%20filter%20(2).pdf https://pdfs.semanticscholar.org/64c6/1b4e6214a6c6ab4e325794f41bae0109e6d9.pdf
I cannot attach my input image here as its in .tif format. I downloaded it from DRIVE DATABASE. Below is the link of DRIVE database.
Below is attached my .m file. Please help me to improve segmentation. Kindly guide me to improve my results.
