Retinopathy of Prematurity
What is retinopathy of prematurity?
Retinopathy of prematurity is an eye problem that happens to premature babies. The
retina lines the back of the eye. It receives light as it comes through the pupil.
From there, the optic nerve sends signals to the brain. Retinopathy of prematurity
is a problem of the blood vessels of the retina. It occurs in stages. It can cause
bleeding and scarring throughout the retina. This may cause the retina to detach.
A detached retina can cause loss of eyesight.
What causes retinopathy of prematurity?
Doctors don't know what causes this condition. Babies who are born too early (premature)
or at a lower birth weight are more likely to get retinopathy of prematurity. In premature
babies, the blood vessels of the retina may not have the chance to develop as they
Who is at risk for retinopathy of prematurity?
Babies who are born prematurely are most likely to get this condition. Babies who
weigh less than 2 pounds, 12 ounces and are born before 31 weeks of the pregnancy
are at greatest risk.
What are the symptoms of retinopathy of prematurity?
Retinopathy of prematurity has no signs or symptoms. The only way to detect it is
through an eye exam by an eye doctor.
How is retinopathy of prematurity diagnosed?
An eye doctor (ophthalmologist) will look at your baby's retinas. The doctor should
have experience treating retinopathy of prematurity. Babies should be screened if
- Weigh less than 3 pounds, 5 ounces at birth. They should also be screened if they
were born before 30 weeks or pregnancy.
- Weigh 3 pounds, 5 ounces to 4 pounds, 7 ounces at birth and are at higher risk for
the condition. They should also be screened if they were born after 30 weeks of pregnancy
but are at higher risk.
Doctors use a special system to describe retinopathy of prematurity. They use it to
figure out treatment and timing of follow-up exams.
How is retinopathy of prematurity treated?
Your baby will be checked regularly, based on his or her condition. That is all most
babies need. Retinopathy of prematurity goes away without treatment.
If your baby needs treatment, the doctor can use a laser to stop the growth of abnormal
blood vessels. Or the doctor may use cold therapy (cryotherapy). Some forms of the
condition are treated with injections. But the long-term effects of these injections
aren’t yet known.
Two surgeries may be done for babies with partial or total retinal detachment:
- Scleral buckling. In this surgery, a band is placed around the eye to push a detaching retina back in
- Vitrectomy. In this procedure, the surgeon removes the gel-like substance inside the eye. This
lets the surgeon better reach the back of the eye. He or she then injects a substance
to hold the retina in place.
After treatment, your baby will be checked often. Your baby should have regular exams
by an eye doctor.
Can retinopathy of prematurity be prevented?
Preventing premature births is the key to preventing this problem. Finding the condition
early and getting treatment can help prevent long-term vision problems.
