2014;98(5):679–83. A pseudo-convergence insufficiency occurs if an accommodative dysfunction inhibits vergence. Springer Nature remains neutral with regard to jurisdictional claims in published maps and institutional affiliations. Hi Everyone! An understanding of the close association between accommodative function and convergence isimportant. Symptoms were quantified using the Portuguese version of the CISS (Convergence Insufficiency Symptom Survey). Convergence insufficiency is a very common condition, characterized by the following: Exotropia greater at near than at distance (at least 10 prism diopters difference) Causes symptoms of “asthenopia” (fatigue with reading, diplopia at near, intermittent blurred vision when reading) Article  Measurement of habitual refractive prescription with a lens meter. Divergence. Validity and reliability of the revised convergence insufficiency symptom survey in children aged 9 to 18 years. Other ways to limit visual distractions are to keep the main learning space clear of extraneous posters, charts or decorations, along with conscious choices for seating the child. The use of an extra sheet of paper to block out extra information can be helpful in creating the white space that is needed. Positive and negative relative accommodation were assessed us- ing a visual acuity card situated at 40 cm and with the maximum plus for best visual acuity correction placed in the phoropter. They will pass a school screening. The fact is, vision impacts learning. In convergence insufficiency, eye misalignment occurs when focusing at near target. This causes what is known as asthenopia, a situation in which people experience discomfort and difficulties performing the kinds of tasks where close focusing is necessary. There are a lot of classroom set-ups these days that have children not facing the board or at an awkward angle. However, this is not necessarily the best for a child with vision deficits. CAS  http://creativecommons.org/licenses/by/4.0/, http://creativecommons.org/publicdomain/zero/1.0/, https://doi.org/10.1186/s12886-019-1061-x. 372 children were assessed from a total of 412 students (response rate of 91%). Convergence and accommodative insufficiency represent the main cause of complaints during close visual work and can reduce visual performance and comfort. If you have this condition, one or both eyes move outward when you look at a nearby object. Convergence is the action of turning the eyes inward as one looks at a near object. AI is mostly observed to occur with a vergence problem especially convergence insufficiency due to the close link between accommodation and convergence system of the eyes. Optom Vis Sci. The CI rate found in this study is somewhat lower than the results reported in other studies with similar methodology (see Table 3). Data was also excluded from children who presented visual Acuity at distance or near, worse than 0.1 logMAR (0.8 in decimal system) in at least one of their eyes, or a difference greater than two lines of VA between the two eyes; with uncorrected refractive errors greater than 0.50D in Myopia, 1.50D in Hyperopia and Astigmatism. Determining the cause of an accommodative dysfunction is important prior to deciding on a treatment approach. Accommodative insufficiency (AI) is a condition that affects the ability to maintain near vision focus for a prolonged time. As stated by the CITT group, the presence of one, or more than one sign of CI allows classification of the visual condition at different levels, from suspected to definite [8]. Google Scholar. To classify CI, a low suspect CI presented the 8th criterion; a high suspect CI presented criterion 8 and other criterion (9 or 10); a definitive CI presented three criteria (from 8 to 10). Convergence Insufficiency (CI) is a binocular vision dysfunction, characterised by the patient’s inability to accurately converge, or sustain accurate convergence when focussing on near objects. Correspondence to We have seen several cases, usually in adolescents, but also in adults. In addition, due to the high rate of comorbidity of CI and AI, several authors have evaluated the frequency of AI in their studies [5, 9]. PubMed Google Scholar. The demographic characteristics for all volunteers assessed and for each clinical grouping are expressed in Table 2 (school year, gender and score symptoms reported by CISS questionnaire). Grouping of CI into the three categories shows that a large percentage of cases found with this condition were classified as low suspect CI (51.2%), a condition requiring the lowest number of characteristic signs of CI. The literature has shown a high rate of comorbidity of CI and AI [5]. The purpose of this study was to estimate the frequency of these conditions in children in 5th and 6th school years in inland Portugal and to assess the impact that each visual condition has on their quality of life, based on the level of visual symptoms. Limiting visual distractions and over stimulation is a large part in helping kids with visual deficits. A prevalence of 6,8% could be considered if clinically significant CI (high suspect and definite categories) cases are accounted. The data collection was carried in the school over a three months. Convergence insufficiency and Reading study (CIRS) group. For the most significant forms of CI (high suspect and definitive), the rate of occurrence was 6.8%, while in other studies rates ranging from 7.75 to 20% were found [5, 9, 10, 18, 22]. Accommodation Insufficiency (AI) is a condition in which a patient has an inability to focus or maintain focus at near. What is Convergence Insufficiency? Optom Vis Sci. A proper diagnosis of CI can prevent a child from being labelled as “lazy,” “spacey,” “clumsy”, “anxious,” and even misdiagnosed with ADHD , dyslexia , … Part of Rule out combined accommodation insufficiency and convergence insufficiency. For children with convergence insufficiency in this age range, identification and treatment with vergence/accommodative therapy are likely to improve vergence and accommodation function, 26 which could make reading and schoolwork more comfortable. Accommodations for visual problems can address visual needs through changes in seating, presentation of visual information, test information, or classroom activities without modifying what is tested, completed, or taught. Risk factors. Data was acquired in the following order: Symptoms (CISS questionnaire Portuguese version); Refractive measures; Binocular Vision and Accommodative measures according to the scheme shown in Fig. Optom Vis Sci. 2010;87(3):168–75. Convergence insufficiency means the eyes struggle to focus easily for near tasks, affecting school work, attention and office performance in adults. © 2021 BioMed Central Ltd unless otherwise stated. Google Scholar. Classroom Accommodations Colorado COVD Study Group Jen Simonson, OD, FCOVD . Borsting E, Rouse MW, Deland PN, et al. The inability to concentrate for long periods during near visual work can reduce the level of student achievement, so CI and AI are presented as negative factors in relation to health and quality of life, as both interfere with reading and near work, contributing to diminished performance at school [1, 3, 4]. One recent study seeks to distinguish these two geographical areas and although the rural area has revealed a lower rate, it is in the same order of magnitude of the rate found in urban areas [17]. Clin Exp Optom. Optom Vis Sci. 2003;74(1):25–34. Improvement in academic behaviors following successful treatment of convergence insufficiency. AI is mostly observed to occur with a vergence problem especially convergence insufficiency due to the close link between accommodation and convergence system of the eyes. Indian J Ophthalmol. The OT Toolbox assumes no responsibility for errors or omissions that may appear in the Website. Keep the kiddo’s work space limited to a name tag and one other item. 2,3 Patients with “pseudo-CI” accommodative insufficiency (AI) will show an improved NPC with a non-accommodative target. 2010;3(4):185–97. These findings need to be clarified emphasizing not only aspects related to geographic location and socioeconomic issues, but also factors related to the design of epidemiological studies and clinical procedures. For the push-up method, the subjects initially viewed the target at a distance of approximately 40 cm and then the target was moved slowly toward the child along the ruler. This set of three processes - technically termed convergence, accommodation, and miosis - is known as the near triad. Each child is different and finding the right visual supports is a trial and error process that takes time and patience to work through. Also limit that amount of ‘work’ that is place in front of the kiddo. AFN carried out the study design, managed the experiment, collected the database, performed the statistical analysis and results analysis, and drafted the manuscript. Accommodation is the action of changing the focus of the eyes when one looks at a near object. Used only to search for the presence of stereoscopic acuity. Optom Vis Sci. 2012;89(1):12–8. Deficient Stereopsis 4. To further identify a pseudo-convergence insufficiency, place a +0.75D lens OU on top of the habitual near prescription and repeat the NPC. What Do Pediatric Occupational Therapists Do. These visual distractions may cause the kiddo to feel visually unorganized leading to the appearance of sloppy work and poor time management, and even signs of anxiety. Convergence insufficiency (CI) is an eye disorder where your eyes don’t move at the same time. For CI classification, the guidelines proposed in more recent studies about CI were followed, where the condition is classified in cases of suspected and cases of definite CI [7, 9, 10]. Convergence and accommodation are two separate neuro muscular actions that are interrelated. For this study, all students enrolled in the 5th and 6th year of education in the group of schools of the city were invited to attend. More recently, a longitudinal study was published by Jorge et al. CI & accommodation: Psuedo-CI is an important differential to make when diagnosing a convergence insufficiency. Convergence and accommodative insufficiency represent the main cause of complaints during close visual work and can reduce visual performance and comfort. 1999;76:643–9. For instance, crayon boxes and utensils may be shared at a table or grouping of students. To further identify a pseudo-convergence insufficiency, place a +0.75D lens OU on top of the habitual near prescription and repeat the NPC. Momeni-Moghaddam H, Kundart J, Askarizadeh F. Comparing measurement techniques of accommodative amplitudes. The test was stopped at the point of consistent diplopia. In convergence insufficiency near point of convergence will recede, and positive fusional vergence (PFV) will reduce. The data used in the current study is available from the corresponding author (Amélia Fernandes Nunes) upon request. 2016. https://doi.org/10.1155/2016/6963976. J Optom. The room provided by the school was suitably adapted, ensuring adequate conditions in terms of test distances and lighting levels. We talked about the anatomy of the eye a while ago, but we didn't talk about convergence. In Group A (73 patients), fusional convergence and divergence amplitudes, NPC, and AC/A ratio were studied and compared with a control group. Inter-examiner repeatability of heterophoria tests. When it doesn’t work, is when the child needs to utilize this information. This little known plugin reveals the answer. A developmental optometrist will complete a full evaluation and determine the need for corrective lenses, vision therapy or a home program to address vision concerns. Knowing their prevalence among schoolchildren is fundamental to define strategies for action. Convergence is the ability of the eyes to move medially, towards the nose, which allow for single vision of closer objects – the ability to cross your eyes, therefor Convergence insufficiency is the inability to do so. Purpose. Horwood AM, Toor S, Riddell PM. Color coding can also be a helpful tool in providing visual structure for older children. One way to help eliminate visual distraction within the workspace is to limit what is on the child’s desk. (CISS- Convergence Insufficiency Symptom Survey; VA – Visual Acuity). 2017; doi.org/10.1016/j.optom.2017.10.002. 7.7% had convergence insufficiency with accommodative excess. Get the latest tools and resources In addition, it is important to test the near point of accommodation (both monocularly and binocularly), as a combined insufficiency of accommodation and convergence can sometimes occur. The Mann-Witney test was used when studying the differences between two groups and the Kruskal-Wallis test when comparing the differences between more than two groups. Relationship between accommodative and vergence dysfunctions and academic achievement for primary school children. Convergence Insufficiency will impact ability of all tasks at near 2. 2002;79:779–87. Manage cookies/Do not sell my data we use in the preference centre. The complaints of visual discomfort are broad and in clinical examination may not be associated with an increased effort on ocular convergence and focus. I have a bachelors in Health Science from Syracuse University at Utica College, and a Masters in Occupational Therapy from Utica College. ● Direction in which the child is facing in relation to the board or main work area Shin HS, Park SC, Parh CM. García-Munoz Á, Carbonell-Bonete S, Cacho-Martínez P. Symptomatology associated with accommodative and binocular vision anomalies. In Group B (in 20 patients), myopia-phoria while switching fr… Studies in children have higher rates, and the frequency is reduced with the increase in criteria for diagnosis of CI [6, 7, 9, 10]. Cacho P, García A, Lara F, Seguí M. Diagnostic signs of accommodative insufficiency. Convergence is the action of turning the eyes inward as one looks at a near object. A pseudo-convergence insufficiency occurs if an accommodative dysfunction inhibits vergence. Good news is that there are some accommodations that can be made in the classroom to assist the child. Convergence Insufficiency (CI) is a binocular vision dys-function, characterised by the patient’s inability to accur-ately converge, or sustain accurate convergence when focussing on near objects. However, the methodology applied in this study was the most suitable for the type of work performed, since it required the use of portable material to permit the evaluation of all the children in their normal school environment. Keywords: accommodation, accommodative insufficiency, optometric vision therapy, near plus add, bifocal Introduction and Review Accommodative insufficiency is an anomaly that is characterized by an inability to focus or sustain focus at near. Although you can have one without the other, they often both cause a problem because accommodation and convergence are closely intertwined neurologically. Experimental studies show reduced vergence parameters and tonic adaptation. statement and This procedure of classifying cases of CI has been followed by other authors [5, 9, 10], which has led to comparable results. Convergence insufficiency or paralysis Convergence insufficiency or paralysis may be functional in nature. On the other hand, it was verified that AI is a visual condition with similar frequency to CI, which requires additional investigation. Significance: These data confirm the effectiveness of office-based vergence/accommodative therapy for improving convergence in children with symptomatic convergence insufficiency. In relation to AI, a frequency rate of 10% was recorded, and 3% of the evaluated children presented AI and CI together. Review studies carried out with school samples, have reported AI rates ranging from 0.2 to 32.5% [16, 17]. Negative and Positive Fusional Vergences at near with horizontal prism bar and a column of Sloan letters 20/30 size at 40 cm as stimulus. age) and with the CI definition used (1 or more criteria). Sometimes limiting visual distractions is not enough support for visual organization. A retrospective review of the records of 96 patients with accommodative insufficiency has been completed. 2001;24(4):205–12. convergence insufficiency also had the signs needed to be present in the accommodative excess. Students with visual impairments will flourish with effective classroom accommodations for visual problems. Comparative studies of phorias measurement between the cover test and other techniques, conclude that the measure obtained by the cover test leads to lower magnitudes [27, 28]. A comparison of subjects with convergence insufficiency and subjects with normal binocular vision using a quality of life questionnaire. Often times when vision is discussed as a concern, a parent or caregiver may push back saying that the child has had their vision checked, and that they can see fine. Convergence insufficiency (CI) is a condition in which a person’s eyes have a tendency to drift outward when looking at objects at near distances, and their ability to converge (rotate the eyes towards each other) is inadequate. … If accommodation is inhibiting vergence, the add lens will relax accommodation and allow the NPC to improve. It is often associated with a host of symptoms that occur when doing near work, such as reading and computer viewing. Convergence Insufficiency is when a child’s eyes are unable to converge inside the midline, or are unable to maintain a position of convergence for an extended period of time. Data on refraction, binocular vision and accommodative function was collected. As occupational therapists, it is imperative that we rule out vision problems before treating handwriting or delays in visual motor integration, to ensure the best possible trajectory of development and success for the child. It can also be mentioned that the scores on the CISS questionnaire between students with NBV and students with low suspect CI are similar and the conditions of high suspect and definite CI are the ones presenting the highest scores on the symptom questionnaire. It is best to have the child facing the board straight on or with a slight angle if they are not seated in the center. In the push-down method, the accommodative target was advanced toward the subject until a significant blur was produced, and then the target was pushed away until the subject could just read the letters [21]. If other items are needed on the desk or workspace, have them arranged so that they are not in the child’s direct line of sight while working. Despite education, and handouts, the parent still resists getting a more in-depth vision evaluation for their child. Accommodative insufficiency (AI) and convergence excess (CE) are associated with high values of NRA, and the dysfunction of convergence excess combined with accommodative excess (CE AE) is related to a normal-high value of NRA. Typically, one eye will turn outward (intermittent exotropia) when focusing on a word or object at near. When visual problems exist, it can be be helpful to next address what to do about those problems to maximize learning. Differential diagnosis • Convergence paralysis: – Total lack of ability to overcome any amount of base out prism. Terms and Conditions, California Privacy Statement, Ophthalmic Physiol Opt. Background: Accommodative insufficiency (AI), accommodative infacility, and convergence insufficiency (CI) are some of the most common visual problems following traumatic brain injury (TBI). Most people think that windows are distractions for kiddos, but for a child with vision deficits, sitting near or facing a window can give a much needed visual “break” from stimulation. Or utilizing the Handwriting Without Tears lined paper versus traditional triple lined paper. People with CI may have symptoms when trying to perform near-based activities such as reading, working on a computer or smart phone, watching video, or playing … The statistical analysis to study the differences between groups was based on nonparametric tests, due to the great disproportionality between groups. 2. 3.1% had basic exophoria. 6.2% showed accommodative insufficiency. Below, you will find strategies that school-based occupational therapists can use as accommodations for addressing visual needs while meeting educational goals. Methods. BMC Ophthalmol 19, 58 (2019). Nunes, A.F., Monteiro, P.M.L., Ferreira, F.B.P. Divergence is the opposite of convergence and is the ability to turn the two eyes outwards to look at a distant object. The higher the amount of white space, they less likely a child with vision deficits is to struggle. ASN participated in the statistical analysis, editing and review of manuscript. This visual screening tool was created by an occupational therapist and provides information on visual terms, frequently asked questions regarding visual problems, a variety of visual screening techniques, and other tools that therapists will find valuable in visual screenings. When visual problems exist, it can be be helpful to next address what to do about those problems to maximize learning. In some studies, the reported prevalence rates include only students with small refractive errors [5, 9], and/or are performed in clinical settings, and this might result in a bias, since the most deprived children tend not to participate in these studies. 2,3 Porcar E, Martinez-Palomera A. Kids and teenagers with headache complaints, somnolence while reading, loss of concentration in performing near vision activities, among other visual stress complaints, must be submitted to an evaluation of binocular vision and accommodation status. Convergence insufficiency and accommodative insufficiency in children. This can be due to eye muscle imbalances and weakness, weak supporting … 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 So, the patient use execessive accommodation to stimulate accommodative convergence to overcome reduced PFV. This is one of the few times that it is okay to have a child’s back to the board or main work area. Upon purchase, you will be able to download the 10 page file and print off to use over and over again in vision screenings and in educating therapists, teachers, parents, and other child advocates or caregivers. Accommodations are strategies set forth that allow a student to change the method of how learning happens. Cite this article. Accommodative insufficiency is commonly present in people with convergence insufficiency. For children with convergence insufficiency in this age range, identification and treatment with vergence/accommodative therapy are likely to improve vergence and accommodation function, 26 which could make reading and schoolwork more comfortable. This causes what is known as asthenopia, a situation in which people experience discomfort and difficulties performing the kinds of tasks where close focusing is necessary. There are a few keys points to preferential seating for kiddos with vision deficits that should be considered. Regarding the symptoms, there were no significant differences in the CISS score between gender or between school year. I practice primarily in a private clinic, but have experience with Medicaid and home health settings also. Cookies policy. If children were found with a poor VA (worse than 0.1 logMAR) or a significant uncorrected refractive error (greater than 0.50 myopia, 1.00 hyperopia or astigmatism) they were referred to an optometric clinic setting, due to suspected uncorrected refractive error. Optom Vis Sci. In addition, children were excluded if they had changed glasses in the last two weeks or present constant strabismus, nystagmus or vertical phoria at distance or near. However, an AI rate (with and without CI) was slightly higher than the rate of significant CI. 372 children (192 girls) were assessed, with average ages of 10.9 ± 0.9 years. Suppression Visual Perception The panq was going to blay in the qark. Our results are closer to the results obtained by White and Wajuihian, which are related to prevalence studies in different geographic areas and countries with different degrees of development [10, 22]. CI has been associated with the visual demand for school requirements, so it is expected that in rural areas and in less developed countries there will be a lower rate of CI than in more developed countries and urban areas. Participants’ ages ranged from 10 to 14 years old with a mean and standard deviation of 10.9 ± 0.8. Understand the pathway for the near reflex and importance of convergence insufficiency. This is okay if the child is not expected to copy work from the board or utilize information from the main learning space. Translation and validation of convergence insufficiency symptom survey (CISS) to Portuguese - psychometric results. Rouse MW, Borsting E, Deland PN, Group C. Reliability of binocular vision measurements used in the classification of convergence insufficiency. If there is too much information in front of them or around them, they are more likely to get lost visually, leading to more time needed to complete tasks and increases in errors when copying or missing written steps. This position would also benefit a child with who struggles with filtering visual information and needs information to be limited on one side. I say ‘work’ lightly as most ‘work’ for kids are worksheets and craft projects. Frequency of convergence insufficiency among fifth and sixth graders. odqy’s father blayep the prum in the qanb. This can generally be done during the comprehensive case history. Effect of cumulative nearwork on accommodative facility and asthenopia. Usually AI was defined by reduced accommodative amplitude, high values on monocular estimation retinoscopy and failing monocular accommodative facility with minus lenses [6, 8, 15, 16]. An average in the order of 5% has been taken as the rate of prevalence of CI in the general population [1, 7]. All children in the 5th and 6th years from the city’s schools were invited to participate in the study. However, visual distractions can also come from items in the child’s work space. In convergence insufficiency, the eyes do not move inward effectively to allow accurate focusing on something near. Once your child has been tested and determined that to have CI, the next step is working with the school to create either an Individualized Education Program (IEP) plan or a Section 504 plan. It should also be noted that 29 students presented signs of AI (~ 10%) and 9 of these cases presented signs of CI with AI (one of low suspect CI, five of high suspect CI and three of definite CI). https://doi.org/10.1186/s12886-019-1061-x, DOI: https://doi.org/10.1186/s12886-019-1061-x. ● Level of visual distractions around the room including posters, boards and other children This study revealed a frequency rate of CI in children of the 5th and 6th year of school that varied between 2% for a more conservative diagnosis, requiring the presence of the three criteria, to 14% for a more liberal diagnosis, requiring the presence of only one criterion. Hussaindeen JR, Rakshit A, Singh NK, et al. 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. All measurements were performed with their habitual refractive prescription. Children were excluded if they had learning disabilities (e.g. Post-hoc analyses were carried out to identify which categories differ, regarding the level of symptomatology, and the results show that there is statistical difference only between NBV and CI in definitive form (p = 0.032). This study has been approved by the Ethics Committee of Beira Interior University (CE-FCS-2012-027). For AI the same criteria as other similar studies, were used [5, 15]. This research is very important since, (1) it is the first in Portugal; (2) it reports on frequency of NBV, CI and AI in a school-based sample (rather than clinic based) and includes students with significant but corrected refractive error (therefore, the sample is more representative of a school population); and (3) it presents the impact that each visual condition has on the quality of life, based on the level of visual symptoms. What is Visual Tracking? To find out whether the different scores on the symptoms questionnaire between the different groups are significant, the differences were studied using the Kruskal-Wallis test, which showed significant differences in at least one of the categories (N = 206; H = 9.052; p = 0.029). Despite education, and handouts, the parent still resists getting a more in-depth vision evaluation for their child. On the other hand, previous epidemiological studies on binocular alterations, carried out in Europe, were performed with university students or generalised age groups [23, 25, 26], which makes it difficult to compare the results obtained in children or adolescents, as they differ of how they spend their time (from leisure time to food habits). This little known plugin reveals the answer. Sometimes changing the handout or worksheet is not an option and other strategies need to be utilized. Regarding CI with and without AI, statistical evidence was found to state that the differences are significant (Kruskal-Wallis test: N = 41; H = 6.524; p = 0.011), Distribution of scores on the CISS questionnaire (0–60), by AI (Accommodative Insufficiency), with and without CI. ACCOMMODATION. Researchers from the CITT group (Convergence Insufficiency Treatment Trial Investigator Group) have quantified the symptoms reported by patients with a questionnaire developed for this purpose, the CISS (Convergence Insufficiency Symptom Survey).
