Accommodative and binocular vision (BV) conditions are about nine times more common than ocular disease in patients six months to 18 years old.1 Of these, approximately 20% have a binocular vision condition (Table 1).1 Also there is special ruler for convergence and accommodation test. Elsevier limited, 2016, Frank Eperjesi PhD, Hannah Bartlett PhD, Mark Dunne PhD Ophthalmic Clinical Procedures Elsevier limited, 2007. The etiology of isolated CI, not related to trauma or neurological disease, has not been completely determined. It is important to understand that a finding of 20/20 vision does not mean perfect or even good enough vision. The only remedy is to strengthen your eyes muscles by regular eye exercises. Normal near point of convergence is about 6-10 centimetre for normal eyes but the convergence recovery point (CRP) is until 15 centimetre. This test is more realistic to typical near viewing situation. Patients with a poor convergence while reading something can suffer from headache and diplopia. Test results should be written down for example convergence 8 centimetre (Brock String). This condition causes one eye to turn outward instead of inward with the other eye creating double or blurred vision.Convergence insufficiency is usually diagnosed in school-age children and adolescents. Answer: This is a test that the optometrist does in order to test the ability of your eyes to come together effectively as you focus close to. The results of the test should be noted for example, NPC 7cm, CRP 12 cm. People also can complain of blurred words after reading. Convergence can be affected by the functioning of the muscles and varies with age. If there is a high level myopia or hypermetropia test should be done with needed correction in advance. A comprehensive eye exam including specific analysis of visual skills, binocular vision, convergence and focusing is required to enable identification of CI. The eye doctor in Delhi should be able to diagnose the condition with a health history and eye tests, generally. The eye that maintains fixation is the dominant eye. This is a standard test for convergence ability. Two test paradigms involve the presentation of small target spots to each eye to evoke convergent or divergent eye movements by moving toward the nose or away from the nose. The fixation target is a pen or pencil. If the near point of convergence (NPC) is more than 10 centimetre there is sign of poor convergence. Convergence Disorder or Convergence Insufficiency results as disposition of the eyes while focusing on close objects. The exact reason is not identified, but the disposition occupies the muscles that shift the eye. We all spend a lot of time scanning the computer screens or browsing text on paper as an unavoidable part of our life. Surprisingly patients with poor convergence can also be asymptomatic. Why does the optician have to get so close during the eye examination. Patient should sit down in a comfortable chair with looking directly at the fixation object that is placed at the nose level approximately 50 cm from it. Mosby, 2013. And suggest the appropriate Convergence Exercises and other forms of treatment, after assessing the degree of the problem. Moving the target too fast that can over estimate the convergence ability or moving the target too slow so the child can lose the interest of doing the test. To get the child's attention a small toy with common character can be used. If you need more help, you can contact us by searching for your nearest store below. A person can pass the 20/20 eye chart test and still have convergence insufficiency. The closest point where the patient can see these two lines crossing at the fixation point is the near point of convergence (NPC). Patient will be asked to fixate at the farthest point at the card and should be asked: If the patient can fixate to this point then move it to the closer point until the patient sees two parallel lines or just one line (in this case the other eye is suppressed).
