Hi!!!

Hope you are doing well.

Getting DNB Opthalmology with NEET PG rank 21100 is quite tough. I am mentioning some colleges where you chances are quite decent.

1. T.D Medical College: Pharmacology.
2. Amrita Institute of Medical Sciences: General Surgery.
3. GMC, Thirssur: ENT.
4. GMC, Thiruvanantapuram: Physiology.

For more details you can go through the link below.

Hope you are clear now. Feel free to ask if you have any other queries. All The Best!!!
