17430 Retinopathy Of Prematurity

Overview

Retinopathy of prematurity (ROP) is an eye problem that can happen in babies who are born too early. In the womb, the eye's retina (the light-sensitive layer at the back of the eye) grows blood vessels slowly and in a careful pattern. When a baby is born early, these blood vessels can stop growing normally or grow in the wrong direction. This can lead to scarring and, in severe cases, vision loss.

ROP is uncommon in full-term babies. It is most often seen in babies who are born very early (before 31 weeks) or who weigh less than about 1.25 kilograms (2.75 pounds) at birth.

ROP affects babies who are born prematurely. The earlier the baby is born and the lower the birth weight, the higher the risk. It often appears in both eyes and is more common in babies who received oxygen therapy after birth.

Symptoms

Common symptoms

• ROP usually has no outward symptoms in the early stages, which is why screening is so important.
• In advanced stages, you may notice the baby's eyes moving abnormally (jittery or wandering).
• The baby may not seem to respond to light or objects as expected.

Symptoms in children

• Young children with a history of ROP may develop crossed eyes (strabismus) or a lazy eye (amblyopia).
• They may need glasses at a young age because of nearsightedness or astigmatism.
• In rare cases, a child may have difficulty seeing even with glasses.

Symptoms in older adults

• ROP is a condition of premature babies, so it does not first appear in older adults. However, people who had ROP as babies are more likely to develop vision problems later in life, such as retinal detachment or glaucoma.

Causes

Main causes

• Premature birth interrupts the normal growth of blood vessels in the retina.
• High levels of oxygen given to premature babies can damage the delicate blood vessels in the eye.
• After birth, the retina may grow abnormal blood vessels that are fragile and can leak or scar.

Risk factors

• Being born before 31 weeks of pregnancy.
• Having a birth weight under 1250 grams.
• Receiving oxygen therapy, especially for a long time.
• Having other health problems at birth, such as anemia or breathing difficulties.

When to see a doctor

See a doctor urgently if:

• If your baby develops any eye redness, uneven pupils, or a white glow in the eye, see a doctor or eye specialist the same day.
• If you are worried your baby may not be seeing, contact your health visitor, GP, or eye specialist promptly.
• If your baby's eyes are suddenly crossing or wandering, get an urgent appointment.

Book a routine appointment if:

• All premature babies at high risk will have eye screening appointments arranged by the hospital before they go home.
• Keep all scheduled eye check-ups, even if your baby seems to be seeing well.
• If your baby has mild ROP, they may need follow-up checks to make sure the eyes heal normally.

Diagnosis

ROP is diagnosed by an eye doctor (ophthalmologist) who checks the baby's retina. The baby's pupils are widened with special eye drops, and the doctor uses a small light and magnifying lens to look inside the back of the eye. This is called a retinal exam.

Tests that may be done

• Retinal examination (using an ophthalmoscope).
• Digital retinal imaging, where a special camera takes pictures of the eye.
• Eye ultrasound in rare cases if the view is not clear.

What to expect at your appointment

The exam can be uncomfortable, but it does not hurt the baby. Eye drops may make the baby's eyes sensitive to light for a few hours. The doctor looks for abnormal blood vessels and decides whether the ROP is mild, moderate, or severe. If treatment is needed, it is usually done within a few days.

Treatment

Treatment for ROP depends on how severe it is and whether the abnormal blood vessels are likely to damage the retina. In many cases, no treatment is needed because the retina heals on its own. When treatment is necessary, the goal is to stop the abnormal blood vessels from pulling on the retina and causing a detachment.

Self-care at home

• Attend all follow-up eye appointments, even if the baby seems fine.
• Protect the baby's eyes from sunlight and bright lights if the doctor advises it.
• After treatment, follow your eye specialist's instructions about eye drops or eye care at home.
• If the baby needs glasses later in childhood, make sure they wear them as prescribed.

Medical treatments

For moderate to severe ROP, doctors may use laser therapy to seal off the abnormal blood vessels. Another option is a medicine injected into the eye to help stop the abnormal blood vessel growth. Both approaches are decided by the specialist based on the baby's condition. These treatments are usually done under anesthesia so the baby feels no pain.

When is surgery considered?

If the abnormal blood vessels cause the retina to pull away or detach, surgery may be needed. This could involve a procedure to reattach the retina or to adjust the inward pressure in the eye. Surgery is reserved for advanced cases that could lead to permanent blindness.

Living with this condition

For most babies with mild ROP, day-to-day life is completely normal. The baby may need regular eye checks until the vision is stable. For children with vision problems, using glasses, low-vision aids, and support from teachers can help them develop and learn.

Lifestyle tips

• Encourage your child to play, read, and explore their world even if they wear glasses or patches.
• Protect the eyes with sunglasses when playing outside during bright days.
• If your child has low vision, make the home environment safe with good lighting and clear pathways.
• Keep up with scheduled visits to the eye specialist even in later childhood.

Diet and exercise

A healthy diet rich in vitamins, especially vitamin A, is important for overall eye health. If your child wears glasses, make sure they wear them during exercise and sports. For babies, follow normal feeding and growth checks; healthy weight gain helps development, including the eyes.

Mental health and emotional wellbeing

As a parent, learning that your baby has ROP can be stressful. If your child needs treatments or has permanent vision loss, it can feel overwhelming. It is normal to feel anxious or worried. Talk to your health visitor or GP about your feelings and ask about counselling or parent support groups.

Prevention

ROP cannot always be prevented, because it is linked to prematurity. However, careful management of oxygen levels in premature babies can reduce the risk or the severity of the disease. Once a baby is born early, regular eye screening is the best way to catch and treat ROP early.

Vaccines

Vaccines do not prevent ROP. But keeping your baby healthy and up to date with routine immunizations protects them from other infections that could complicate their overall health and development.

Screening programmes

Screening is essential. Babies born prematurely are checked for ROP at regular intervals, starting shortly after birth. This is typically arranged by the hospital's neonatal team. Screening helps find problems before they cause vision loss, which is why it is so important to attend every appointment.

Complications

If left untreated

• Development of scar tissue that pulls on the retina.
• Retinal detachment, where the retina peels away from the back of the eye.
• Permanent blindness or severe visual impairment.
• Later childhood problems such as crossed eyes, lazy eye, or glaucoma.

Long-term outlook

The outlook for ROP is generally very positive. Many babies with mild ROP recover fully without treatment, and even babies who need laser or injection treatments usually do well with good vision. When treatment is successful, most children can see well and lead normal lives, though they may need glasses or regular eye checks. Early detection and timely care are key.
