Overview
I am a Duke vitreoretinal surgeon and Moorfields uveitis trained ophthalmologist, specializing in patients with complex medical and surgical problems of the back of the eye, known as the retina, as well as patients with inflammation in the eye or uveitis. I use the latest diagnostic and therapeutic methods along with a collaborative team effort with colleagues across Duke Eye Center and the Duke Rheumatology and Immunology division to develop the optimum treatment plans for patients with uveitis. Outside of work, I enjoy spending time with the family, traveling, watching sports, and landscape photography.

Additional Areas of Focus
Dr. Grewal has provided the following conditions as areas of focus. Please note that we may not have enough data to validate their experience in some of these conditions.
Clinical Research
Clinical research consists of overseeing clinical studies of patients undergoing new treatments and therapies, and publishing articles in peer reviewed medical journals. Providers who actively participate in clinical research are generally at the forefront of the fields and aware of the most up-to-date advances in treatments for their patients.
Duke Spine Center - Clinic 1B/1C
I have had the privilege of providing neurosurgical care at Duke Health since 1995 with the majority of that time focused on cervical spine disorders. By involving my patients in their own care through careful histories, examinations, and a thorough review of imaging studies, we are able to use that process to plan on whether conservative care or possible surgery will relieve their pain and get them back to living at their best. I have performed over 6,500 cervical spine procedures and perform approximately 350 cervical spine surgeries per year, focusing on great outcomes and short stays. 98% of patients are in the hospital less than 24 hours after surgery. I have been recognized as the top cervical spine surgeon in the country by MPIRICA Health Inc. based on my outcomes. According to ProPublica, I have the lowest complication rate in North Carolina. I hope through my extensive clinical experience to provide excellent diagnostics and, through an outstanding team, provide the very best surgical results. My belief is that by combining the technical and spiritual sides to my practice, patients have the very best outcomes and together we accomplish amazing results for them.

As a pediatric otolaryngologist and head and neck surgeon, I provide kids and their families a unique perspective and understanding of the natural clinical history of medical problems that may arise. I am passionate and dedicated to helping kids with both routine and complex head and neck problems, including performing cochlear implant surgery, and value the natural collaborative nature of taking care of children and their families. Being involved with kids and their families is one of the most gratifying and satisfying privileges that I have had the fortune of experiencing. I hope to continue to build these relationships and watch the kids that I help take care of grow up. Dr. Cheng is rated as an Advanced provider by MediFind in the treatment of Traumatic Brain Injury.
