convergence insufficiency test online

It makes it hard to focus on things nearby. Convergence insufficiency (CI) is a problem with the way the eye moves. These are all needed to determine if you do have convergence insufficiency. Data analyses were performed using Statistical Analysis System (version 9.2, SAS Institute Inc., Cary, North Carolina, USA) and Statistical Package for the Social Sciences (version 15, SPSS Inc., Chicago, Illinois, USA). CISS, near point of convergence, positive fusional vergence, accommodative amplitude of the right eye, and accommodative facility of the right eye were performed according to CITT protocol.16 The CISS was administered before tests of vergence or accommodative function by a screener masked to the other screening tests. The first sustained blur was considered the endpoint. Draw a straight line in the middle and across the length of a sheet of paper or cardboard. You will be shown how to do these exercises. Convergence insufficiency has a reported prevalence among children and adults in the United States of 2.5 to 13% 1). Procedure 1. All rights reserved. A ROC curve shows the trade‐offs between the false positive rate (1‐specificity) versus the true positive rate (sensitivity). The result is a single, focused image. International Journal of Environmental Research and Public Health. Orthophoria with convergence dysfunction was classified as orthophoria with positive fusional vergence ≤ 15∆ to base‐out blur (break if no blur) and a receded near point of convergence of ≥ 6.0 cm. Of the 282 children tested, approximately 20 per cent had 2–3 signs of CI. 1 Mallett RFJ (1964) The investigation of heterophoria at near and a new fixation disparity technique. To diagnose convergence insufficiency, your eye doctor might: 1. Amplitude of accommodation was among the top three tests for identifying those with symptomatic three signs of convergence insufficiency. While the focus of treatment is often on symptomatic convergence insufficiency,9 this study evaluates screening for both symptomatic and any convergence insufficiency given that there may be interest in the detection of all children with convergence insufficiency (symptomatic and asymptomatic) to allow referral for follow up. Receiver operating characteristic curve analysis was performed to evaluate the ability of each test to identify subjects who were classified as having convergence insufficiency. This is done while you look closely at something. Convergence Insufficiency Symptom Survey If you or your child struggle with near oriented visual tasks, like reading/learning, writing or computer work, this free online vision test helps determine if a Developmental Vision Evaluation is needed. Convergence Insufficiency is a common vision problem that can make reading or staying on-task quite difficult for school-aged children. In some cases, the symptoms of CI don’t go away with treatment. But it does not help correct CI. Near point of convergence testing was performed using a single column of letters of 6/9 (20/30) equivalent at 40 cm on a near point rule (Gulden Ophthalmics, Elkins Park, Pennsylvania, USA). For detection of convergence insufficiency with three signs, the ratio of positive fusional vergence over the phoria also performed among the best tests, but this would require testing both positive fusional vergence and phoria and determination of the ratio. Screening tests of vergence and accommodative function were performed by trained student optometric clinicians. Learn more. Extreme tiredness (fatigue) also can bring on symptoms. Blur, break and recovery values were measured three times. When reading, the eyes and brain also have to do quick, complex eye movements to look across and down a page. However, the best screening test for CI is unknown. It also does not give you practice working with both eyes together, which is important in order to correct CI. Convergence insufficiency is normally seen in school-age children and adolescents at the age of 16. You may need to do them regularly at home. Diagnosis of Convergence Insufficiency (CI) Individuals with convergence insufficiency might have otherwise normal vision (20/20), so it is important to mention reading or learning concerns to your eye care provider. Near point of convergence and amplitude of accommodation testing are tests that a nurse and/or lay screeners may be able to be trained to perform; therefore, further research should evaluate the effectiveness of screening for convergence insufficiency with one or both of these tests when performed by a nurse and/or lay screeners.
