One in four school aged children have a vision impairment that gets in the way of their learning
Vision problems more common in children with disabilities
An infant’s eyes should be checked as soon as possible for abnormalities and muscle imbalance to reduce risk of permanent vision loss
Early detection improves success of medical treatment
The child’s teacher is usually the first to notice clues in a child’s behavior that might suggest a vision disorder
Unlikely that young children will recognize when their vision isn’t normal
Special attention should be paid to children with known physical disabilities
Delays in identifying vision problems could affect learning process
Methods of Assessment
Any concerns should be discussed with the child’s family
Routine screenings are essential
Teachers and volunteers can be trained to administer many standardized visual acuity tests
Children’s eyes should be checked for
Deviations in pupil position
“lazy eye”, approximately 2% of children younger than 10 have this.
Caused by a muscle imbalance or childhood cataracts resulting in blurred/double vision.
Refractive Amblyopia: One type of lazy eye, called refractive amblyopia, is caused when one eye is more nearsighted or farsighted than the other, making it difficult for the eyes to focus together.
StrabismicAmblyopia: Another common cause of lazy eye is strabismus. Strabismus, often referred to as a crossed or wandering eye, is a condition in which the brain is unable to properly align the eyes.
Treated by having the child wear a patch over the stronger eye until muscle strength improves in weaker eye . Other methods for treatment include eye drops, corrective glasses, and special eye exercises
Teachers may be asked to help give treatment, be supportive, and make accommodations for students.
Common disorders (cont’d)
“crossed eyes”, causes observable misalignment of the child’s eyes . May experience double or blurred vision, images from weaker eye ignored by brain, and gradual loss of vision
Children with obvious crossed or wandering eyes have to deal with the self-consciousness arising from questions, stares, and teasing from their peers.
Early recognition is essential for restoring normal vision
Several methods are used to treat strabismus:
Patching of unaffected eye
Common disorders (cont’d)
“nearsightedness”, meaning they can see near objects but cannot see far clearly
Problematic for young children because they move quickly
Squinting is common
Teachers can note these behaviors and refer children for screening
Families should be counseled and encouraged to arrange for professional screening
Teachers can help families understand why it is important to follow through with any recommendations
Arrangements can be made through pediatrician’s office, public schools, etc.
Children who don’t pass initial vision screening should be retested
Results should be read with caution because it does not guarantee that there is or isn’t a problem
Visual acuity changes over time; VERY important for teachers and families to be aware of children’s visual performance
How would I address this as a teacher?
I would address the importance of going to the eye doctor and making sure that your vision is okay.
If necessary, if children give those with visual impairments any problems or grief, I will construct the class not to.
