Differentiate your Private Practice from All Others

A Game Changer For Your Practice

Independent optometry faces challenges like never before: patients can purchase their eyewear on-line; optometric chain stores are seemingly everywhere; and the finances dictate that you must see more patients in less time.

It doesn’t have to be like this.

  • Become a healer, making fundamental changes to your patient’s quality of life
  • Get off the treadmill and spend more time with your patients, as this financially viable practice model is based upon caring for only eight patients per day
  • Be treated like a medical subspecialist, integrating into the medical community and getting referrals from across the entire spectrum of physicians (including ophthalmologists)
  • Add a new patient stream and revenue stream to your practice

Drs. Mark Rosner and Debby Feinberg have done some remarkable work in helping patients with headaches and vertigo who were previously told there was no help for their debilitating problems. They didn’t do it with drugs, surgery, or VT. They did it with prism. Yes – eyeglass lenses with prism. And more often than not, they prescribed very, very small amounts of prism. So small in fact, that most doctors would swear, “There’s no way that minute of a correction could solve that big of a problem.”

A New Optometric Specialty – NeuroVisual Optometry

NeuroVisual Optometry, developed by Dr. Debby Feinberg, involves the identification and treatment of patients with Binocular Vision Dysfunction (BVD) using fractional units of realigning prism. This financially viable practice model enables the optometrist to identify and successfully treat the 10% of the population who have BVD symptoms that are not usually thought of as being visually mediated:

  • Headache
  • Nausea
  • Light sensitivity
  • Dizziness
  • Neck pain
  • Gait imbalance
  • Anxiety
  • Motion sickness
  • Reading/learning/concentration problems/dyslexia/ADHD/etc…
  • Persistent symptoms associated with TBI/concussion

Layperson’s Explanation of Binocular Vision Dysfunction

(as found on the Vision Specialists of Michigan website)

  • People suffering from Binocular Vision Dysfunction have a small amount of eye misalignment (shown by the black arrow) that causes the image (dotted red arrow) to not be on the center of the back of the eye:
    Diagram 1 - BVD - Visual description of Binocular Vision disorder

  • They overuse and strain their eye muscles to correct the misalignment:
    Diagram 2 - BVD - Visual description of Binocular Vision disorder

  • Now the image is on the fovea, but the overused and strained eye muscles cause the many symptoms of Binocular Vision Dysfunction.Diagram 3 - BVD - Visual description of Binocular Vision disorder

  • While the body is doing its best to fix the eye misalignment, this approach causes a lot of problems. There has to be a better way to get the image onto the fovia without straining to reposition the eye. And there is!

  • Since 1995, the doctors at Vision Specialists have performed groundbreaking research into the use of prism (in green) which is at the heart of our Vis-AlignTM Glasses. Prism bends beams of light and redirects the image (red dotted arrow) onto the center of the back of the eye (the fovea – big red arrowhead) while the eye is in its original, slightly misaligned position (black arrow). As there is no need to realign the eye, there is no overuse of the eye muscles, which markedly reduces or eliminates the symptoms of Binocular Vision Dysfunction.

Dr. Debby Feinberg
NeuroVisual Optometry Training Program

Dr. Debby Feinberg, Director of Clinical Care, Vision Specialists of Michigan, has been performing pioneering work with Binocular Vision Dysfunction (BVD) with emphasis on Vertical Heterophoria (VH) and Superior Oblique Palsy (SOP), conditions of eye misalignment that cause headaches, dizziness, imbalance, anxiety, light sensitivity, neck pain and reading difficulties. She has treated more than 8,000 patients with BVD, of which more than 3,000 have been TBI / ABI patients. Her research (which has been presented locally, nationally and internationally) demonstrates that BVD is common in those TBI patients experiencing persistent post-concussive symptoms and treatment with prismatic eyeglass lenses reduces these symptoms by 80%. She authored a book on VH patients and their experiences with VH and with prismatic lens treatment. She is a co-author of a peer reviewed article on TBI and VH.
