The Importance of Vision Screening

A child’s vision is still developing and can be vulnerable to eye disease. Untreated infection, refractive error and misaligned eyes can harm vision. By finding and treating problems early, healthy vision can develop. Learn about childhood eye conditions and screen your child regularly to protect their vision.

Refractive errors

Refractive errors cause blurry vision. A child can have trouble seeing at near distancesfar distances, or both. If a child does not see correctly for long enough, they can lose vision and get a “lazy eye.” Correct your child’s refractive error with the right prescription glasses.

An eye is too short lengthwise in a farsighted eye, so light rays fall beyond the retina. Near objects are blurry when a child is farsighted. 

Amblyopia

Amblyopia is poor vision in an eye that did not develop vision normally in childhood. It’s also called “lazy eye.”

A child can get amblyopia when they do not get treated for problems like refractive errors, strabismus (misaligned eyes), droopy eyelids or cataracts.

Strabismus

Strabismus (misaligned or crossed eyes) happens in about 4 percent (4 out of 100) children. One eye may look straight ahead while the other turns in, out, up or down. Strabismus needs to be treated as soon as possible.

Without strabismus treatment, the brain may ignore the crossed eye to avoid double vision.

Ptosis

Ptosis is a droopy eyelid that can block vision. If the eyelid droops very low, your child may need surgery to raise it. The raised eyelid helps preserve vision in that eye.

“Cloudy” eyes

A child’s eyes can appear cloudy if they have a cataract. This is when the normally clear lens inside the eye gets cloudy. Older people mostly get cataracts, but some children are born with them or get them from an injury. Most children need surgery to remove a cataract and see clearly again.

Very rarely, a cloudy eye can be a sign of retinoblastoma (cancer of the retina, or back wall of the eye). Your child’s doctor checks for this at each exam.

Cellulitis is an infection of the eyelid or the eye socket. Symptoms include:

  • painful swelling or bulging of the eye
  • fever
  • blurry vision
  • problems with eye movement

The infection can spread quickly to other parts of the body and needs immediate treatment.

Conjunctivitis (pink eye)

Conjunctivitis is irritation of the white part of the eye from infection or allergy. Pink eye can be viral or bacterial (both very easily spread, or contagious) or allergic (not contagious).

A child’s eyes may be red, itchy, teary or have a sticky discharge. Keep your child home from school if they have contagious pink eye. Pink eye usually goes away on its own in a week. You can usually control symptoms at home, but sometimes a doctor prescribes antibiotic eye drops.

Stye and Chalazion

A stye is a red, sore lump at the edge of the eyelid. It is caused by a bacterial infection. Warm compresses are used to treat styes with an antibiotic in some cases.

A chalazion is a swollen lump on the eyelid caused by a clogged oil gland. It is not caused by infection. You can usually use warm compresses at home to treat a chalazion.

Blocked Tear Duct

Twenty percent of babies (2 out of 10) are born with a blocked tear duct. Tears do not drain normally, which causes a watery, irritated or infected eye.

Your doctor may show you a special massage technique to help open the tear duct. If massage doesn’t help after a few months, your ophthalmologist may use an instrument to open the duct.

Remember, a child might not tell you their vision is blurry, and symptoms can go unnoticed by parents or teachersProtect your child’s vision with regular screening and eye exams.
