Vision problems are common among children, with 19 million worldwide living with a vision disorder.1 Oftentimes, vision disorders have no noticeable symptoms,2 and as a result, children may not realize they see the world differently than others.3
Uncorrected vision disorders can impact a child’s cognitive, emotional, neurological, and physical development, potentially resulting in behaviour problems, interference with early literacy and learning, and even permanent vision loss.4 Paediatric vision screening is the first line of defence for detecting potential vision problems early, when treatment is more likely to be effective.5
To help provide clarity around paediatric vision screening, we have compiled the most common questions and answers regarding this vital test.
A vision screening is a method used to identify children who may have an eye condition that could lead to vision loss.4
Amblyopia is the #1 cause of vision loss in U.S. children.6 It is defined as decreased vision in one or both eyes due to abnormal development of the vision system.7 The earlier the treatment, the more likely it will be successful.5 If left untreated, the child may become blind in the amblyopic eye.8
A vision screening can help detect potential eye problems at an early age when treatment is most effective.4
The American Academy of Paediatrics (AAP) recommends that children receive an instrument-based vision screening at 12 months of age and chart-based testing when the child can read a visual acuity chart (typically around 3-5 years old).9
An instrument-based vision screener can help detect common vision-threatening conditions such as nearsightedness, farsightedness, blurred vision, unequal refractive power, eye misalignment, and unequal pupil size.10
Children may not realize they see the world differently than others and oftentimes vision disorders have no noticeable symptoms.3
A vision screening can help detect a vision problem, but a comprehensive dilated eye exam by an eye doctor (optometrist or ophthalmologist) is necessary for diagnosis.
No, dilation drops are not necessary for a vision screening.11
Your child will be referred to an eye doctor for further examination. It is imperative that parents follow through with this recommendation as only an eye doctor can formally diagnose and treat vision disorders.
Yes, periodic comprehensive eye exams are key to evaluating overall eye heath. During the exam, various tests are performed to assess visual acuity, depth perception, eye alignment, and eye movement.12 Eye drops are used to dilate the pupil, enabling a more thorough investigation of the eye.
Paediatricians and family doctors often conduct vision screenings during well-child visits. In addition, vision screenings can be performed in schools by school nurses or at community-based events by trained laypersons.
