It is important to note that most routine eye exams will not include specific testing for CI, so it is important that the patient or parent explains in detail the symptoms he/she is having. They also highlight the importance of using a primary outcome measure that is as objective as possible rather than relying solely on self-reported symptoms for studies of binocular vision in children. A complete pediatric eye exam with cycloplegic dilation i… This is the brain's answer to coping with double vision and the stress of eyes not working as a team. Read our, Medically reviewed by Johnstone M. Kim, MD, Medically reviewed by Jonathan B. Jassey, DO, Lacrimal Bone: Anatomy, Function, and Treatment, How to Use Visual Therapy Exercises for Lazy Eye, Focusing Problems in Children and How to Fix Them, 8 Ways to Reduce Eye Strain While Working From Home, What You Should Know About Viral Conjunctivitis. Don’t underestimate the influence that a condition such as convergence insufficiency can have on a child's or young adult’s reading ability, concentration, comprehension, and education. If these symptoms (all or some) are noted, extra testing can be performed to diagnose or rule out CI. Consequently, a person with convergence insufficiency who is suppressing one eye can show some or all of the following symptoms: In summary, CI is a common but frequently missed diagnosis (one can have uncorrected vision in each eye of 20/20 vision and still have CI so screenings at work and school will totally miss it). Convergence insufficiency is a weakness of convergence (when the eyes are unable to keep looking at an object approaching the nose). Accommodative dysfunction is an eye-focusing problem resulting in blurred vision—up close and/or far away— frequently found in children or adults who have extended near-work demand. J Vis. CI is not a condition caused by a muscle weakness. A person that has a good fusional vergence can keep the target single all the way “to the nose.” An NPC of only 10 cm is considered remote or outside of normal limits. Convergence insufficiency (CI) is a treatable near vision disorder and eye muscle coordination problem that can not be repaired with eye surgery, medications, standard eyeglasses, or contact lenses. Frequent spilling or knocking over objects. Barnhardt C, Cotter SA, Mitchell GL, Scheiman M, Kulp MT. Procedure 1. Treatments for Convergence Insufficiency The article states that pencil push-ups is the most commonly prescribed treatment for convergence insufficiency, but that is because many optometrists do not refer patients to vision therapy departments. Many patients will complain that they have difficulty concentrating on near work (computer, reading, etc.) When we are not able to converge our eyes easily and accurately, problems may develop, such as: Convergence insufficiency is a condition in which your eyes are unable to work together when looking at nearby objects. CI is usually accompanied by a reduced near point of convergence (NPC), decreased convergence amplitudes or an exodeviation (usually > 10 prism diopters) at near. All of which are common symptoms … Symptoms will be worsened by illness, lack of sleep, anxiety, and/or prolonged close work. The accommodative system and the convergence system of the eye are closely intertwined and one can affect the other. In the case of CI, treatment is part of the prevention. The eyes become tired and sore easily. Eye coordination problems like convergence insufficiency generally cannot be improved with eye glasses or surgery. Convergence insufficiency (CI) is when the eyes have trouble working together while focusing on an object that is close by. When we are not able to converge our eyes easily and accurately, problems may develop, such as: Symptoms of convergence insufficiency include diplopia (double vision) and headaches when reading. The symptoms and signs associated with convergence insufficiency are related to prolonged, visually demanding, near-centered tasks. Do You Have Symptoms of Macular Degeneration? Avoidance of tasks that require depth perception (games involving smaller balls traveling through the air, handicrafts, and/or hand-eye coordination, etc.). They also highlight the importance of using a primary outcome measure that is as objective as possible rather than relying solely on self-reported symptoms for studies of binocular vision in children. This is because if the condition is not properly treated, it can progress into a much more serious condition called intermittent exotropia. American Academy of Ophthalmology, Eye Wiki [internet]. It may not always be evident that someone suffers from convergence insufficiency because the symptoms may vary. Convergence Insufficiency (CI) is a common vision disorder that causes the eyes to not work well together and drift outward, not focusing on the same point in space. Headaches 3. Problems with motion sickness and/or vertigo. Children experiencing convergence insufficiency have failed to adeq… Think of it as the lenses doing the work the nerves don’t know how to do. Symptoms of Convergence Insufficiency. Passive treatment is more like a crutch that works only when in place. Fortunately, there are several clinical tests that can objectively diagnose convergence insufficiency (all of which have age-based norms to figure out is your kid just being a kid). Inclusion criteria included the following three signs of CI: (1) exophoria at near at least 4Δ greater than at distance, (2) insufficient positive fusional vergence (PFV) at near, and (3) a receded near point of convergence (NPC) of 6 cm break or greater. Most eye care professionals treat convergence insufficiency using a home-based therapy called “pencil push-ups.” During pencil push-ups, the patient follows a small letter or picture on a pencil. ): They are said to have a low accommodative-convergence/accommodative ratio. The process the author uses to treat convergence insufficiency has been very efficient, effective and repeatable. Consequently, a person with convergence insufficiency who is suppressing one eye can show some or all of the following symptoms: Trouble catching balls and other objects thrown through the air. Treatment can be active or passive. Convergence insufficiency is not usually detected on regular vision screenings. This is the most common eye muscle disorder among children and adults. This allows near objects to become clear. First, eye doctors find that a patient suffering from convergence insufficiency has a large exophoria. They may also experience fusional-vergence dysfunction, in which they are unable to efficiently utilize the information that their eyes take in. You do not have access to this content. Oman J Ophthalmol. Many patients will complain that they have difficulty concentrating on near work (computer, reading, etc.) Symptoms are generally resolved in 8 … 5 It should be noted that there are multiple mechanism for this condition, but recent studies have shown a … He is an active member of the American Optometric Association. The study found that approximately 75 percent of those who received in-office therapy by a trained therapist plus at-home treatment reported fewer and less severe symptoms related to reading and other near work compared to individuals who had home-based vision therapy alone.. Convergence describes the way our eyes move together and point inward when we look at near objects. A baby can’t do it, but by age 2 or 3, most children can.
