Binocular Vision Disorder (BVD) Facts and Figures

A person can pass the 20/20 eye test with eye tracking issues.

12 out of 100 children are affected by binocular vision disabilities.

5% of school age children have Convergence Insufficiency (CI).

In the past, BVD has gone undetected because testing is not included in:

  1. Pediatrician's eye tests
  2. School screenings, or
  3. Basic eye exams.

Nearly 16% of children diagnosed with ADHD also test positive for Convergence Insufficiency (CI).

Approximately 1 in 8 (13%) 5th/6th Graders examined had CI.

Approximately 1 in 5 (17.6%) 8th-12th graders examined had CI.

The 5 symptons that overlap with ADHD, which can cause misdiagnosis of ADHD are:

  • Irritability
  • Low self-esteem
  • Inability to concentrate
  • Loss of concentration when reading, and
  • Trouble remembering what they read.

80% Of all learning during a child's first 12 years comes through vision. (Pediatric Vision Development Center of Gwinnett, 2013. www.visiontherapy4kids.com)

Ohio State Ophthalmology recently conducted a test of approximately 250 students who had received an IEP (Individual Education Program). These students were tested for eye tracking disorders. Of the 250 students tested, seventy six percent (76%) of the students tested suffered from at least one BVD, and in many cases the child suffered from multiple BVDs.

Good News

About 75% of kids who had weekly office-based and at home treatments experienced full correction of their vision in 12 weeks or experienced major marked improvements.

Bad News

Due to a lack of testing for CI and other BVDs, many people are not getting the help they need early in life.
