A New Approach to Phoria Screeing & Testing


There are hundreds of patients currently in your practice who suffer from the sysptoms of subtle eye misalignments like Vertical Heterophoria. The tools on this page will give you the ability to identify these patients.

There are two main tools that are utilized to identify VH: the Binocular vision Dysfunction Questionnaire (BVDQ) and the 5-Minute Cover Test. Both are quick and easy to administer.


The BVDQ is the most powerful and reliable tool developed to identify those who most likely have Vertical Heterophoria and will respond to treatment. This validated survey instrument asks about a wide array of questions from the 7 main symphom groups, resulting in identification of many VH sufferers.

The BVDQ is the first step for every patient on thir NeuroVisual Medicine healing journey. Having the power to identfiy these patients and transform their lives (i.e - 80% reduction symptoms) is something NeuroVisual Medicine Specialists cherish.

The 5-Minute Cover Test

While the BVDQ, informs the doctor that the patient would benefit from a NeuroVisual Examination, the 5 Minute Cover Test demostrates this need to the patient.

If the patient experiences symptom relief while being made monocular during the 5-Minute cover test, they most likely have a binocular vision issue, clarifying to them that obtaining a NeuroVisual Exam is their patway to feeling better.

Take the Next Step

After trying these two tests with your patients, you will quickly become aware of the large number of your patients who could benefit from a NeuroVisual Examination and treatment with microprism lenses, as well as the finacial impact that caring for this patient population could have upon your practice. Don't miss out on this opportunity to transform your patients lives: become a NeuroVisual Medicine Specialist and learn how to diagnose and successfully treat their Vertical Heterophoria.
