Prism lenses work by bending light so that the near object appears to be in a different location than where it is truly located. Surgery is a rare treatment for convergence insufficiency. For people who have just learned to live with it, there’s good news. Methods: A total of 175 subjects with normal binocular vision and 38 subjects with convergence insufficiency were evaluated.

Convergence of the eyes occurs when the two eyes need to focus on a close object, such as a book, computer, tablet, smartphone, etc. One of the most well-known vision therapy exercises used to correct convergence insufficiency is known as “pencil push-ups.” It also makes it hard to read and focus.

If you do have symptoms, various treatments can improve or eliminate the problem. Secondary convergence insufficiency is a difficulty with convergence that is due to deficient accommodation, or eye focusing. Eye coordination problems like convergence insufficiency generally cannot be improved with eye glasses or surgery. Convergence insufficiency is most common in young adults, but it can affect people of all ages. The increased accommodative and convergence effort … With vision therapy, the eye is trained to turn inward when looking at near objects, correcting the neu-muscular problem that prevents the eyes from rotating inward. It can also decrease distance judgement, coordination, and sports performance. An ophthalmologist, optometrist, or orthoptist can diagnose convergence insufficiency. * Functional vision involves your ability to see an object in space, and includes visual skills such as eye movements, eye teaming, eye focusing and depth perception. Both eyes should point at the same spot and perceive visual space equally in order to work as a team. CI is typically amid a reduced near the point of convergence (NPC), decreased convergence amplitudes or an exodeviation at near. The prisms work by bending light, which forces you to see a single image. Learn how undetected vision problems can impact a child's ability to learn. Convergence insufficiency is a condition that occurs when the eyes do not work together properly, and cannot turn inwards at the same time for clear, single vision of a nearby object. Eye coordination problems such as convergence insufficiency and convergence excess generally cannot be improved with eye glasses or surgery. Prism lenses work by bending light so that the near object appears to be in a different location than where it is truly located. Other estimates are as low as 2.5% of the population. When reading, people with convergence insufficiency frequently lose their place or have to re-read text. It may not always be evident that someone suffers from convergence insufficiency because the symptoms may vary.

If you have this condition, one or both eyes move outward when you look at a nearby object. Convergence Insufficiency and Convergence Excess describe a difficulty in the ability to point both eyes at a near target, like a book, tablet, or computer. Convergence insufficiency interferes with a person’s ability to read, learn, and work within arms reach.

According to a study conducted by the Convergence Insufficiency Treatment Trial group, office-based vision therapy with home reinforcement is the most effective method for strengthening the convergence skill. Patching simply does not correct the underlying cause of the outward deviation and the reduced eye teaming ability. It may…. This is called vision suppression. Patients with non-strabismic binocular vision disorders—such as divergence insufficiency, basic esophoria and vertical heterophoria—can often benefit from treatment with prism, particularly relieving prism, while others—including those with convergence excess, convergence insufficiency, divergence excess or basic exophoria—are better managed with other treatment modalities, such as … This article will explain the most effective treatments for CI, and help you to understand why they are most effective. Symptoms. This coordinated movement is called convergence. When you look at a nearby object, your eyes move inward to focus on it. They work by increasing eye convergence. Results.

The condition can be treated with eye exercises, but like any other form of exercise, you have to do it in order to reap the results. Convergence Insufficiency (CI) is defined by a limited ability to converge the eyes and have binocular fusion while that practices in a near target. However, it’s associated with conditions that affect the brain. This can cause eyestrain, headaches, or vision problems like blurred or double vision.
