This might include questions about problems you have with focusing, blurred or double vision, headaches, and symptoms. The near point of convergence (NPC) is a simple test performed in clinic that can reveal abnormalities about the binocular vision system.A reduced NPC in isolation is synonymous with a diagnosis of Gross Convergence Insufficiency.Convergence ability can be affected in traumatic brain injuries or be inherent to a weakened binocular vision system. This requires a special program that can be used on a home computer. This can result in discomfort and even double vision when performing near-point tasks such as reading. Convergence insufficiency, or convergence dysfunction, is a common binocular vision disorder in which the eyes do not work at near easily. Moreover, patching affects binocular vision, and therefore can cause other vision difficulties such as poor depth perception— which can impact your performance of most daily activities. This coordinated movement is called convergence. When base-in prism reading glasses were compared with placebo reading glasses, investigators found no evidence of a difference in the three outcome measures of near point convergence (NPC), positive fusional vergence (PFV), or symptom scores measured by the Convergence Insufficiency Symptom Survey (CISS). Also know if Convergence Disorder or Convergence Insufficiency is permanent, can glasses be used to treat Convergence Disorder or Convergence Insufficiency and if the treatment for it is successful or not.

Student t test, chi‐square, or nonparametric tests at the 0.05 level were used for statistical significance. For the PLRG test, the patient wears red/green glasses and fixates on a penlight as it is moved towards the patient’s nose. Although you can have one without the other, they often both cause a problem because accommodation and convergence are closely intertwined neurologically. Computer exercises are also game-like, so they can be fun for kids and teens.

It often leads to loss of concentration/attention when reading. Generally, computer vision therapy is more effective than other home exercises. The near point of convergence (NPC) is a simple test performed in clinic that can reveal abnormalities about the binocular vision system.A reduced NPC in isolation is synonymous with a diagnosis of Gross Convergence Insufficiency.Convergence ability can be affected in traumatic brain injuries or be inherent to a weakened binocular vision system. In some extreme cases patients may benefit from glasses with prism to alleviate their symptoms, or eye muscle surgery if the symptoms are also present at a distance. The eyes have a strong tendency to drift outward when reading or doing close work. Its effectiveness is less consistent in adults. So, if you have trouble reading or doing close work, visit an eye doctor. Patching simply does not correct the underlying cause of the outward deviation and the reduced eye teaming ability. Convergence may be thought of as the ability to cross the eyes; as funny as this may sound, we do need this ability every time we perform tasks like reading or using a computer. Can Glasses or Eye Patches Treat Convergence Insufficiency? It may not always be evident that someone suffers from convergence insufficiency because the symptoms may vary.

Methods: A total of 175 subjects with normal binocular vision and 38 subjects with convergence insufficiency were evaluated. Background: Convergence insufficiency is a common binocular vision disorder in which the eyes have a strong tendency to drift outward (exophoria) with difficulty turning the eyes inward when reading or doing close work. Accommodation is the automatic reflex that occurs when we focus on a near object. 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. The eye muscles in people with CI work normally. Convergence Insufficiency (CI) is a common eye-teaming problem in which the eyes have difficulty turning in to read and see during up close work. It is the most common cause of ocular asthenopia. Measure the near point of convergence (NPC). Without proper testing, convergence insufficiency will go undetected because testing is not performed in a basic eye examination, school screenings or your pediatricians office. They help convergence ability by reducing near point of convergence. Convergence Insufficiency (CI) is a common eye-teaming problem in which the eyes have difficulty turning in to read and see during up close work. What about prism lenses?
