Grant Michael Comer MD, MS

Grant M. Comer, MD, MS, specializes in diseases and surgery of the retina and vitreous, including the diagnosis and management of diabetic retinopathy, age-related macular degeneration (AMD), retinal vascular disease, ocular trauma, infectious chorioretinitis, and retinal detachments. In the clinic, Dr. Comer strongly believes that all patients deserve the ability to make treatment decisions best suited to their needs. He will often spend considerable time reviewing the problem with patients and family members using a plastic eye model and individual images, discussing the management options, and answering questions before helping patients make a final treatment decision. At the end of the appointment, Dr. Comer personally creates a comprehensible management plan for his patients and sends a copy to the patient, in addition to referring doctors.

Dr. Comer is heavily involved in clinical research and serves as the Medical Director of the Kellogg Clinical Research Center (KCRC) and Associate Medical Director of the Ambulatory and Chronic Disease Clinical Trial Support Unit (CTSU). In these roles, he ensures that clinical research teams within the Department of Ophthalmology and across the University of Michigan have the resources to conduct studies safely and effectively. His individual research interests range from developing alternative treatment regimens to halting the progression of vision loss in diseases such as macular telangiectasia, type 2, age-related macular degeneration, and diabetic retinopathy.

Dr. Comer received his medical degree from Indiana University (IU) in 2001. Following an internship at Methodist Hospital in Indianapolis, he completed a residency in ophthalmology at IU in 2005. From 2005 to 2007 he undertook a vitreoretinal, uveitis, and ocular oncology fellowship at the University of Michigan Kellogg Eye Center, and served as a clinical lecturer in the Department of Ophthalmology and Visual Sciences until 2009 when he was promoted to Assistant Professor. In 2009, he also earned a Master of Science in Clinical Research Design and Statistical Analysis from the University of Michigan’s School of Public Health. His bibliography reflects 34 peer-reviewed papers, 5 book chapters, and several abstracts, as well as educational materials for patients.
