Key Facts About Vision Disorders in Children for Your Patients and Staff [Infographic]

Vision disorders are widespread among the pediatric population with one in 20 children at risk for permanent vision loss due to vision disorders like amblyopia.1 Fortunately, with early detection and treatment, 80% of vision disorders can be prevented or cured.2 However, only 1 in 3 American children has received eye care services before the age of six.3

Common Pediatric Eye Problems

Vision loss can be caused by a wide range of factors including damage to the eye, incorrect eye shape, or from a problem within the brain.4 Equal input from both eyes is vital for normal development of the vision system in babies and young children.5 A child's vision may be permanently impaired if eyes are unable to send clear image signals to the brain.5

Up to 10% of preschoolers and 25% of school-age children have a vision disorder that can impact learning and quality of life.6 Here are some of the most common disabling vision disorders among U.S. children:3

  • Myopia (nearsightedness)
  • Hyperopia (farsightedness)
  • Astigmatism (blurred vision)
  • Amblyopia (lazy eye)
  • Strabismus (eye misalignment)
  • Anisometropia (unequal refractive power)
  • Anisocoria (unequal pupil size)

Oftentimes, vision disorders have no noticeable symptoms. Signs that may indicate a potential vision problem include:4, 7

  • Closing or covering one eye
  • Squinting
  • Complaints of blurry objects
  • Difficulty doing close-up work
  • Holding objects close to eyes
  • Blinking more than usual
  • Watering of eyes
  • Red-rimmed, crusted or swollen eyelids
  • Tilting their head

Detecting Vision Disorders in Children

Among preschool children, less than 15% receive comprehensive eye examinations and less than 22% undergo vision screenings.8 The evaluation of the visual system is vital as it can help detect conditions like strabismus and amblyopia that distort or suppress normal visual images and may lead to vision loss.6 Vision screening and comprehensive eye exams are complementary methods for evaluating vision disorders in children.3

Pediatric vision screening is the first line of defense for detecting potential vision problems early on when treatment is more likely to be effective.9 Vision screening is an efficient and cost-effective method that can be conducted by primary care providers, eye care professionals, school nurses and other trained laypersons. Vision screening can help identify children who have or are at risk for developing vision disorders such as amblyopia, strabismus, and various refractive errors (e.g., myopia, hyperopia).3 A child should be referred to an eye care professional if they fail a vision screening test.10

A comprehensive eye exam by an eye doctor (optometrist or ophthalmologist) is required to formally diagnose and treat vision disorders. During the exam, various tests are performed to evaluate visual acuity, depth perception, eye alignment, and eye movement.8 Eye drops are used to dilate the pupil, enabling a more thorough investigation of the eye.

How Instrument-Based Vision Screeners Can Help

An instrument-based vision screener is a device that can help detect vision disorders that may cause visual impairment.11 An instrument-based vision screener takes an image of the eyes to measure refractive error and ocular misalignments and easy as having a photo taken with a digital camera.1, 12 An instrument-based vision screener is recommended for children who are unable to perform a visual acuity chart test.11

What Can You Do?

80% of all learning happens visually.13 Therefore, uncorrected vision disorders may result in impaired development, behavior problems, interference with early literacy and learning, and even permanent vision loss.14

To help facilitate early detection and treatment, the U.S. Preventative Services Task Force (USPSTF) recommends all children between the ages of three and five years receive at least one vision screening to help detect vision problems.8

Additionally, the American Optometric Association recommends that asymptomatic or low-risk children should have a comprehensive eye exam at age three, followed by another exam prior to entering first grade and then at least every two years afterward.3 High-risk children (e.g., born prematurely, family history of vision problems or eye disease, noticeable abnormalities or symptoms of decreased vision, etc.) should bypass a vision screening and be directly referred to an eye care professional.9

To help educate your patients and staff, we’ve created a helpful infographic that conveys the importance of early detection and treatment of vision disorders in children.
