About Dr. Diana Driscoll, OD, FAOO
Diana Driscoll, OD, FAAO
President of Genetic Disease Investigators
Diana Driscoll OD, FAAO, Founder and President of Genetic Disease Investigators, is a world-renowned invisible illness expert and foremost authority on Postural Orthostatic Tachycardia Syndrome (POTS), chronic dry eye disease (DED), Chronic Fatigue Syndrome (ME/CFS), vagus nerve disorders, Ehlers-Danlos syndrome (EDS), and similar “invisible” illnesses. She is the Clinical Director of POTS Care, the only clinic in the world dedicated to treating the underlying medical causes of POTS. Her patient evaluation technique, now called “The Driscoll ApproachTM” recognizes the inflammatory component in many cases of POTS, and is a dramatic departure from traditional evaluation and treatment of POTS.
Dr. Driscoll authored “The Driscoll Theory”, an in-depth, scientific publication revealing the propensity for high intracranial pressure in POTS patients that dramatically altered how the condition was evaluated and treated. She has also authored “Your Eyes and EDS”, was the chief author of the “Ophthalmology Medical Resource Guide” for Ehlers-Danlos National Foundation, and has received three patents to date. She was published in the Journal of VitreoRetinal Disease. She holds a B.A. from the University of Texas at Austin and a Doctorate of Optometry from University of Houston, both summa cum laude.
