cataract is a painless, cloudy area in the lens of the
eye that blocks the passage of light to the retina, the nerve layer at the back
of the eye, usually causing vision problems. Cataracts are rare in babies and children. But a child may be born with them because
of genetics, infection during pregnancy, or low
The earlier cataracts are diagnosed and treated, the more likely it is that sight will be preserved or develop
normally. A baby's vision develops rapidly in the first few months of life. If
a cataract blocks light from entering the eye and stimulating the retina, the
area of the brain used for sight does not develop properly. And lazy eye (amblyopia) occurs. Without surgery in the first few months of life, the child won't ever see well with that eye, even if he or she has surgery later in life.
The signs of cataracts in children include the following:
If a child has a cataract in only one eye, you may not be able to
tell. All children should have regular exams by a family doctor to
screen for these types of cataracts.
Cataracts in infants are commonly detected at birth or during routine
well-child checks. More frequent exams are needed if the child has a medical
condition that increases the risk for cataracts, if he or she seems
to have trouble seeing, or if you notice your child has clouding of the lens.
Children who have vision problems from cataracts
usually need surgery to prevent lasting vision loss and to ensure normal vision
will develop. A small number of children with cataracts may benefit for
a short time from eyedrops that widen (dilate) the pupil. These eyedrops
increase the amount of light getting into the eye. The drops may also
help prevent vision loss in very young children who need to wait for surgery to be done.
Some types of cataracts in children require more urgent treatment
than other types:
Call your child's doctor right away if you see that your child has one eye with a red reflex and one eye without it. The eye with the "white reflex" may have a cataract.
Call your child's doctor if:
