Pediatric Automated Vision Screening:
Vision screening is a cost-effective and efficient way to identify if your daughter or son may have avisual impairment or eye condition that could lead to vision loss. An automated vision screener is used in the office of yourpediatrician or at yourchild’s school, through the regionalLion’s Club International of Connecticut. Here is a slide showing common machines.
Theautomated photoscreener has a special camera which uses thered reflex which helpsidentify risk factors fordecreased vision. The automated photoscreener is especially helpful in children ages 1 to 4 years old.The red reflex should be equal and the same in both eyes.
What if the red reflex test is abnormal or if there is a ‘failed vision screening’ test?
This happens when anabnormal red reflex triggers the photoscreener’s ‘risk factor’ settings in one or both of your child’s eyes. These risk factors can tell us if your childcould be at risk fordecreased vision in the future. Decreased vision during childhood is calledamblyopia.
So, the photoscreener machine is pre-programed to help us assess if your child could possibly be at risk to have a vision problem.
Why is it is helpful to use a photoscreenerso young,especially before 12 months old? It is important to screen at 12 months old or younger because we can tell if therecould be a vision problem months and years before your child could let us know by identifying shapes, pictures, or letters during an office visit.So, this early intervention is really helpful to help children have the best possible vision develop in both of their eyes!
There arefive major risk factor settings on most automated photoscreeners: nearsightedness (myopia), farsightedness (hyperopia), astigmatism (curved shape of cornea and/or lens), unequal pupil size (anisocoria) andstrabismus (eye misalignment).
Does every child who has a ‘failed vision screening’need glasses? The short answer isno. Sometimes the automated machineover calls myopia and astigmatism in children. However—it is important to have a referral to an eye doctor who is comfortable evaluating children for a complete exam. Sometimes, the eye doctor will hold off on giving glasses right away, but still observe and watch your child’s vision closely—maybe needing glasses later in childhood. Other times, the eye doctor will need to give glasses to your child at a young age to help prevent vision loss in one or both eyes—and to help improve vision as soon as possible.

FAQs
If your child fails, they should see a pediatric ophthalmologist – rather than an optometrist – to find out what's causing their vision problem. Pediatric ophthalmologists have advanced training to diagnose and treat all eye conditions in children, from myopia to more complex disorders such as: Amblyopia, or lazy eye.

Can eye doctors make mistakes? ›

Often, the schools will want a child's vision screened before kindergarten.
How to read child vision screening? ›
Depending on the extent of any errors in refraction, your child may be prescribed glasses. On the chart, myopia will be noted with a minus sign next to a number while hyperopia will be recorded with a plus sign. The higher the number, the greater the refractive error and the stronger the prescription.
What happens if you fail a field of vision test? ›
If your visual field test is not normal, you may need additional follow-up testing, as well as treatment. A visual field test can help diagnose scotomas , or blind spots.
