Dr. Mackay is the founding director of Neuro-Ophthalmology at the Indiana University School of Medicine. He is driven by his passion for compassionate patient care, training the rising generation of physicians, and advancing the frontiers of academic medicine.
After completing medical school at the University of Virginia, where he was inducted into the Alpha Omega Alpha Honor Medical Society and the Gold Humanism Honor Society, he completed neurology residency training at Harvard Medical School at the Brigham and Women's Hospital and Massachusetts General Hospital in Boston. He then completed a neuro-ophthalmology fellowship with mentors Drs. Nancy Newman and Valerie Biousse at Emory University in Atlanta.
He joined Indiana University in 2014 and founded IUSM's Neuro-Ophthalmology Clinic, where the clinical volume has increased tremendously, having served well over 7,000 new neuro-ophthalmology patients since 2014. In addition to his busy outpatient clinical practice, Dr. Mackay also serves as an attending neurologist on the inpatient Neurology consult service at Eskenazi Hospital. Dr. Mackay was named Professor of the Year in 2016 and Lecturer of the Year in 2022 by the graduating IU Ophthalmology Residency class and was one of four clinical IUSM faculty members inducted into the Gold Humanism Honor Society in 2019, the same society that honored him as a student 10 years prior. As an expression of his passion for education, he serves as the Statewide Assistant Neurology Clerkship Director for IUSM, the largest medical school in the country, and created and serves as the course director for the Clinical Neuro-Ophthalmology Elective for fourth-year medical students. He holds joint appointments in the departments of Neurology, Ophthalmology, and Neurosurgery, where he serves as an Associate Professor.
He has been invited to speak at regional, national, and international conferences on neuro-ophthalmology subjects and has been an author on dozens of peer-reviewed neuro-ophthalmology publications.
He stays even busier at home with his wife and eight young children, who are the joy of his life. He enjoys spending time with them, serving in his church, and working on cars.
