Eye Teaming Problems, Binocularity, Convergence

One key area for sound vision is the ability of both eyes to capture images, send them to the brain, and for the brain to "see" the final image. The two eyes working together as a coordinated team is called binocular vision (binocularity), and it is responsible for much of our depth perception, an extremely important aspect of vision. Processing images with both eyes enables the visual system to "see" in "3-D" (stereopsis) and judge distances between objects as well as detect movement.

Intermittent blurred vision or double vision is a primary symptom of eye teaming problems.

Intermittent blurred vision or double vision is a primary symptom of eye teaming problems. Less obvious forms of eye teaming stress will also result in irritability, fatique, and avoidance of reading/close work.

The ability of both eyes to work together to process visual stimuli is called eye teaming, and when compromised, hinders the ability to concentrate on close work, makes reading difficult, and may also affect physical coordination in sports, play and other daily activities. The child who easily learns to read in the 1st and 2nd grades, but whose school work suddenly gets worse in the 3rd and 4th grades, often has an eye coordination and/ or focusing problem causing the performance change.

Eye Teaming may also affect coordination, depth perception.

Even when each eye sees clearly by itself, unless the eyes work together - blurred vision and/or a lack of depth perception may lead to coordination problems and/or sports deficiencies.

In order for the eyes to work in tandem, they must be able to turn inward in order to focus on close images such as writing or words. This is called convergence. There are two main types of eye teaming/convergence problems:

  • Convergence Excess: The eyes turn in too much when trying to attend to an object at a near working distance
  • Convergence Insufficiency: The eyes do not turn in enough to adequately attend to the same object

Both types of eye teaming problems may cause double vision, intermittent blurred vision, headaches, fatigue, and avoidance of close work. Children with this disorder are prime candidates to be misdiagnosed with dyslexia, ADD or ADHD, and/or other learning problems.

Treatment of Eye Teaming Problems

Treatment of Eye Teaming Problems includes computers, special glasses, and stereoscopic instruments.

In the case of virtually all Eye Teaming Problems, Vision Therapy is the only way to treat the condition. The treatment program uses a combination of lenses, prisms, instruments, computers with special software programs, and variable demand 3-D techniques to expand the range, speed and accuracy of the patient's eye teaming skills. To supplement "in-office" therapy, complementary home therapy techiques are typically prescribed.

All Vision Therapy programs are custom designed for the symptoms and conditions of each patient. The vision therapy sessions are always conducted under the supervision of a trained behavioral optometrist, and individual procedures in the program are supervised by our vision therapists.
