Biographical narrative

Dean A. VanNasdale, Jr., OD, PhD, received his Doctor of Optometry degree from the Michigan College of Optometry at Ferris State University in 2003 and completed a cornea and contact lens residency at Indiana University in 2004. Dr. VanNasdale received a Master of Science degree in Clinical Research and a PhD degree in Vision Science from Indiana University in 2011.

Dr. VanNasdale’s primary research focus is advanced retinal imaging, with an emphasis on normal aging changes and pathological changes associated with diabetic retinopathy and age-related macular degeneration. By emphasizing specific light/tissue interactions, changes to the normally well-ordered retinal structure can be highlighted. The goal of his research is to distinguish normal aging changes from those related to sight threatening pathology and to detect retinal damage earlier in the disease process using both commercially available and laboratory-based instruments.

Dr. VanNasdale teaches Public Health and Environmental Vision to third year optometry students and is an instructor in the Contact Lens Services at the College of Optometry.
