PEDIATRIC VISION CARE

SIGNS OF POTENTIAL VISION CONDITIONS

Spotting Eye Problems

Signs that a child may have vision problems include:

• constant eye rubbing

• extreme light sensitivity

• poor focusing

• poor visual tracking (following an object)

• abnormal alignment or movement of the eyes (after 6 months of age)

• chronic redness of the eyes

• chronic tearing of the eyes

• a white pupil instead of black
  
  

In school-age children, other signs to watch for include:

• being unable to see objects at a distance

• having trouble reading the blackboard

• squinting

• difficulty reading

• sitting too close to the TV

Watch your child for signs of poor vision or crossed eyes. If you notice any eye problems, have your child examined right away so that the problem doesn't become permanent. If caught early, eye conditions often can be corrected.

VISION CONDITIONS

Several eye conditions can affect kids. Most are detected by a vision screening using an acuity chart during the preschool years.

​

• Amblyopia ("lazy eye") is poor vision in an eye that may appear to be normal. Two common causes are crossed eyes and a difference in the refractive error between the two eyes. If untreated, amblyopia can cause irreversible visual loss in the affected eye. (By then, the brain's "programming" will ignore signals from that eye.) Amblyopia is best treated as early as possible, ideally before a child is 8 years old.

• Strabismus is a misalignment of the eyes; they may turn in, out, up, or down. If the same eye is chronically misaligned, amblyopia may also develop in that eye. With early detection, vision can be restored by patching the properly aligned eye, which forces the misaligned one to work. Surgery or specially designed glasses also may help the eyes to align.

• Refractive errors mean that the shape of the eye doesn't refract (bend) light properly, so images appear blurred. Refractive errors also can cause amblyopia. Nearsightedness is the most common refractive error in school-age children; others include farsightedness and astigmatism:

  • Nearsightedness is poor distance vision (also called myopia), which is usually treated with glasses or contacts.

  • Farsightedness (also called hyperopia), which is usually treated with glasses or contacts.

  • Astigmatism is imperfect curvature of the front surface of the eye, which is usually treated with glasses if it causes blurred vision or discomfort.
    
    

Other eye conditions need immediate attention, such as retinopathy of prematurity (a disease that affects the eyes of premature babies) and those associated with a family history, including:

• Retinoblastoma is a malignant tumor that usually appears in the first 3 years of life. The affected eye or eyes may have visual loss and whiteness in the pupil.

• Infantile cataracts can occur in newborns. A cataract is a clouding of the eye's lens.

• Congenital glaucoma in infants is a rare condition that may be inherited. It is the result of high pressure in the eye from incorrect or incomplete development of the eye drainage canals before birth and can be treated with medication and surgery.

• Genetic or metabolic diseases of the eye, such as inherited disorders that make a child more likely to develop retinoblastoma or cataracts, may require kids to have eye exams at an early age and regular screenings.

GLASSES AND CONTACTS FOR KIDS

Kids of all ages — even babies — can wear glasses and contacts.

Keep these tips in mind for kids who wear glasses:

• Let kids pick their own frames.

• Plastic frames are best for children younger than 2.

• If older kids wear metal frames, make sure they have spring hinges, which are more durable.

• An elastic strap attached to the glasses will help keep them in place for active toddlers.

• Kids with severe eye problems may need special lenses called high-index lenses, which are thinner and lighter than plastic lenses.

• Polycarbonate lenses are best for all kids, especially those who play sports. Polycarbonate is a tough, shatterproof, clear thermoplastic used to make thin, light lenses. However, although they're very impact-resistant, these lenses scratch more easily than plastic lenses.
  
  

Babies born with congenital cataracts may need to have the cataracts surgically removed during the first few weeks of life. Some wear contact lenses after cataract surgery.

Around age 10, kids may want to get contact lenses for cosmetic reasons or if they play sports.

To wear contacts, a child will need to know how to insert and remove lenses properly, take them out as required, and clean them as recommended by the doctor.
