About Us

Transforming Patient Lives, and Optometry Practices

When our founder Dr. Debby Feinberg cared for her first Binocular Vision Dysfunction (BVD) patients in 1995, the scope of this condition was completely unknown. As momentum grew and success treating BVD patients with microprism lenses continued, patients began traveling from across the US and from abroad to seek her care.  We now know that about 20% of the population has Binocular Vision Dysfunction – and without proper care these people go through life experiencing severe symptoms without any answers.

With this as motivation, the NeuroVisual Medicine Institute was founded in 2011 with the mission to bring relief to BVD patients worldwide, by providing independent optometrists with the training and tools they need to become NeuroVisual Specialists in their region. Our Training Program is a complete package that enables the independent optometrist to transform into a NeuroVisual Specialist:

– The latest clinical training
– Practice management tools
– Diagnostic equipment kit

We have now trained over 40 optometrists who have gone on to help 1,000s of patients nationally and internationally. Are you ready to join us in transforming lives?

Debby Feinberg, OD, FAAO

Founder & Director of Clinical Instruction

Dr. Debby Feinberg began performing pioneering work diagnosing and treating Binocular Vision Dysfunction (BVD) and Vertical Heterophoria (VH) in 1995. BVD and VH have been found to cause headaches, dizziness, gait imbalance, anxiety, light sensitivity, neck pain, and reading difficulties in approximately 1-in-5 patients. She and her colleagues at Vision Specialists of Michigan have treated more than 20,000 BVD/VH patients with microprism lenses and noise-canceling devices, of which half have been TBI / ABI patients. Her research (presented nationally and internationally) demonstrates that TBI patients with VH experiencing persistent post-concussive symptoms have 80% reduction in these symptoms when treated with microprism lenses and noise-canceling devices.

Since 2013, over 40 optometrists have successfully completed the NeuroVisual Medicine Training Program™ and have gone on to help tens of thousands of patients. Drs. Feinberg and Rosner’s founding of the NeuroVisual Medicine Institute is led by their mission to increase access to NeuroVisual care for patients in every region across the globe.

Founder & Director of Education and Research

After 30 successful years in Emergency Medicine, Dr. Mark Rosner now leads the NeuroVisual Medicine Institute’s Education and Research division.  He has been actively involved in developing the specialty of NeuroVisual Medicine and in Binocular Vision Dysfunction (BVD) research since 2005, and in 2010, Dr. Rosner co-founded the NeuroVisual Medicine Institute with Dr. Feinberg.  His research efforts have led to the validation of the Binocular Vision Dysfunction Questionnaire (BVDQ™) and co-authorship of peer-reviewed articles on the connection between BVD and TBI.  Dr. Rosner has presented lectures on the topic of BVD and microprism treatment nationally and internationally.

Dr. Rosner’s work on refining the NeuroVisual Medicine™ business model has enabled over 40 practices world-wide to add a meaningful profit center to their clinics, while transforming the lives of optometrists and their patients.
