Due to the nationwide shortage of vision professionals, it can be challenging to locate personnel. Announce a job vacancy on the Job Exchange of Teaching Students with Visual Impairments, an online listing of jobs specific to the visual impairment field.
Convergence Insufficiency (CI) is a common binocular (two-eyed) vision disorder in which the eyes do not work at near easily. It interferes with a person's ability to see, read, learn, and work at near distances. A person can pass the 20/20 eye chart test and still have convergence insufficiency. Treatment that is typically recommended by optometrists includes either passive (prism lenses) to active (office-based vision therapy with home reinforcement). Eye surgery is rarely, if ever, recommended.
CI is an eye teaming problem in which the eyes have a strong tendency to drift outward when reading or doing close work (exophoria at near). If the eyes do drift out, the person is likely to have double vision. To prevent double vision, the individual exerts extra effort to make the eyes turn back in (converge). This extra effort can lead to a number of symptoms which interfere with the ability to read and work comfortably at near. Symptoms may include: eyestrain, headaches, blurred vision, diplopia (double vision), sleepiness, difficulty concentrating, movement of print while reading, loss of comprehension after short periods of reading or performing close activities, frequent loss of place, squinting rubbing, closing or covering an eye. Symptoms will be worsened by illness, lack of sleep, anxiety, and/or prolonged close work.
CI may lead to suppression of vision in one eye causing loss of binocular vision and depth perception. Poor binocular vision may have a negative impact on many areas of life, such as coordination, sports, judgment of distances, eye contact, motion sickness, etc. Recommended treatment by optometrists for Convergence Insufficiency is vision therapy. As with other visual diagnosis, a diagnosis of Convergence Insufficiency in and of itself does not guarantee that a student will be eligible or in need of school based vision services. If a student is found to be eligible, these services would NOT include vision therapy as vision therapy is not provided by schools.
The optometrist may also recommend school accommodations that may assist the student throughout the day. These recommendations are generally simple to provide and may include using a line guide or a bookmark to keep their place while reading, positioning books on a slant board or incline, receiving a copy of notes or information presented on the board and being seated closer to the board. The school can provide these accommodations regardless of a students eligibility for school based vision services.
Although a student with Convergence Insufficiency may need support or accommodations in areas related to vision, they will typically NOT meet the eligibility criteria to be identified as a student with a visual impairment as the criteria for that label is reserved for students who are severely impacted by their vision (see eligibility criteria). Although there are exceptions to the rule, a student who is diagnosed with Convergence Insufficiency and has an otherwise normal eye report will not meet the eligibility criteria for vision services provided by the school.
