It’s common for convergence insufficiency to go undiagnosed. Convergence Insufficiency. According to Cooper & Duckman, the recovery on PFC ranges is probably the more important finding as the “recovery is a better indication of fusional potential over time as it represents the patient’s ability to voluntarily regain fusion on the basis of sensory information.” Regardless of what you decide gives you the most information, all sources point to the fact that the “fusional vergence amplitude must be larger than the magnitude of the phoria to avoid ocular fatigue.”31. You can do these exercises at home. J Neuroophthalmol 2000;20(1):5-11. Convergence insufficiency is a common condition that is characterized by a patient 's inability to maintain proper binocular eye alignment on objects as they approach from distance to near. Secondly this balance must remain stable and unfaltering throughout the task. Obviously, reading requires development of this skill, since most reading is done at a relatively close distance. Healthline Media does not provide medical advice, diagnosis, or treatment. This requires a special program that can be used on a home computer. Plus, school-based eye exams aren’t enough to diagnose convergence insufficiency in children. They help convergence ability by reducing near point of convergence. But for people with symptoms, treatment with eye-focusing exercises can increase the eyes' convergence ability. 2012. Strabismus 2005;13(4): 163-8. During convergence your eye muscles move your eyes closer together so that you can focus on a near point. Your brain controls all your eye movements.

With your doctor’s help, convergence insufficiency can be fixed with visual exercises. For example, convergence insufficiency (CI) is a specific type of intermittent exotropia in which the eyes usually align properly when viewing a distant object, but fail to achieve or maintain proper alignment when looking at close object, such as when reading, resulting in one eye drifting outward. A proper diagnosis of CI can prevent a child from being labelled as “lazy,” “spacey,” “clumsy”, “anxious,” and even misdiagnosed with ADHD , dyslexia , … Now that you have a good understanding of CI signs and symptoms, you’re probably asking “What is the best way to treat it?”  The core of the CITT studies was to determine the most effective and efficient way to treat CI.

Convergence insufficiency results with vergence ability at near is unable to match vergence demand. The Dr that tested her noticed some very odd things in the results, and once she showed me, I saw clearly what she meant. 5 It should be noted that there are multiple mechanism for this condition, but recent studies have shown a consistent etiology … The normal value for NPC, which was found using an accommodative target, was determined as, Adults: <5cm/ 7cm29and Children: <6 cm.30, As stated in the review, “The majority of patients with a CI have reduced PFC ranges.” 6,31,32 It was determined that a PFC of <15 PD is abnormal for both a patient with a CI as well as the normal population. Each of the three signs used to diagnose CI have been extensively studied and with that has come norms to gauge patient’s performances. Convergence insufficiency is most common in young adults, but it can affect people of all ages.
