Dilraj Singh Grewal
Associate Professor of Ophthalmology

Vitreoretinal and Uveitis Specialist

Dilraj Grewal, MD specializes in the medical and surgical management of patients with complex Vitreoretinal pathology and Uveitis. He joined the Duke Eye Center in December 2016 following completion of his Vitreoretinal Surgery fellowship at Duke and Uveitis fellowship training at Moorfields Eye Hospital in London.

Dr Grewal is excited about treating patients with several of the new diagnostic and therapeutic modalities available as well as several others in the pipeline to better help patients with these potentially blinding diseases.

He has been the recipient of numerous prestigious awards including the Ronald G. Michels Foundation Fellowship Award, the Heed Ophthalmic Foundation Fellowship Award, Achievement Award from the American Academy of Ophthalmology and Rhett Buckler and Honor Awards from American Society of Retina Specialists.

Dr Grewal has authored over 80 publications in peer-reviewed medical journal and over 100 presentations at national and international meetings. His research interests span clinical research activities in advanced ocular imaging and clinical trials for both Retina and Uveitis. He also serves as Director of Grading at the Duke Reading Center, a comprehensive image reading center that specializes in systematic analysis of ophthalmic images captured by many different modalities in multicenter clinical trials. In addition, he participates in national and international clinical trials in retina and uveitis.
