Is your little one born prematurely? Or is he or she underweight? Such babies can sometimes have minor health problems. One of them is a condition called Retinopathy of Prematurity (ROP), which is an eye problem. Don't be scared when you hear this name. Let's talk about it simply, in a way that you can understand.
What is this eye problem that occurs in premature babies (Retinopathy of Prematurity - ROP)?
Simply put, ROP is a condition that affects the eyes of some babies born before 31 weeks (prematurely). What happens in this is that abnormal blood vessels form in the part of the baby's eye called the retina . Think of it like the film in a camera. When light hits the eye, it is converted into electrical signals and sent to the brain by this retina. The brain then uses those signals to create images for us to see. So, keeping this retina healthy is very important for the baby to see the world well.
These new, abnormal blood vessels that form in ROP are usually harmless. They do not require any special treatment, just observation by doctors. About 90% of babies with ROP recover without any treatment and regain normal vision. However, sometimes this condition can become more severe and threaten the baby's vision. In such cases, prompt treatment is necessary to prevent permanent damage to the eye and loss of vision. If left untreated, severe cases of ROP can even lead to blindness.
That's why doctors recommend screening at-risk babies for ROP as soon as they're born. These tests can help determine if the baby has symptoms of ROP and whether treatment is needed.
Your baby's doctor will tell you if your baby is at risk for ROP and when to bring your baby in for testing. To reduce the risk of serious damage to your baby's vision, it is essential to follow the testing schedule your doctor gives you exactly.
How common is ROP?
If we look at the statistics in a country like the United States, about 14,000 to 16,000 babies develop ROP every year. Of these, about 90% have very mild ROP. That is, they do not require treatment. However, between 1,100 and 1,500 develop severe ROP that requires treatment. As a result, between 400 and 600 babies become legally blind every year. Although the exact statistics in our country may vary, this is a situation that needs attention.
What are the symptoms of a baby with ROP?
Often, you may not be able to recognize such a major symptom just by looking at your baby. An ophthalmologist is the only person who can accurately diagnose ROP by carefully examining your baby's eyes (especially the way the blood vessels in the retina are formed).
Why does this ROP occur?
The main cause of ROP is a disruption in the normal process of blood vessel formation in the baby's retina.
Think about it, the blood vessels in the retina of the eye begin to form slowly while the baby is still in the womb. These are not fully formed until the baby is born. So, the blood vessels in the retina of premature babies are not fully formed. These blood vessels continue to form after birth, but sometimes they can form abnormally.
Although it is not possible to say exactly which babies will develop ROP, researchers have found that certain factors increase the risk of developing ROP.
What are the risk factors for ROP?
There are several risk factors for this condition:
- Preterm delivery: The earlier the baby is born, the higher the risk of developing ROP.
- Birth weight of 1,500 grams (about 1.5 kilograms, or about 3.3 pounds) or less.
- Respiratory distress syndrome: Difficulty breathing after birth.
- Bleeding within the brain (Intracranial hemorrhage).
- Various infections or other medical problems.
If your baby has one or more of these risk factors, your doctor may recommend that you have an eye exam to check for signs of ROP as soon as your baby is born.
What are the complications of this condition?
If severe cases of ROP are left untreated, a condition called retinal detachment can occur. This is when the baby's retina separates from the supporting tissue around it. Retinal detachment can cause severe vision loss or blindness. This is the most serious consequence of ROP.
How do you accurately diagnose ROP?
Neonatologists in neonatal care units usually identify babies at risk for ROP. They then refer the baby to an ophthalmologist for further testing.
During this test (also called a "screening"), the eye doctor uses eye drops to dilate the baby's iris and look for signs of ROP. Digital pictures of the baby's retina may also be taken. This initial test is usually done between four and six weeks after birth.
The criteria for screening babies for ROP can vary from country to country. In countries like the United States, babies are typically screened for:
- Babies 30 weeks pregnant or less.
- Babies with a birth weight of 1,500 grams (3.3 pounds) or less.
- Babies with higher gestational age or birth weight, but other risk factors for ROP.
Your baby may need additional tests every one to three weeks, or as scheduled by your doctor. Your baby's ophthalmologist will tell you that these tests are no longer necessary once the blood vessels in your baby's retina are fully developed and the risk of retinal detachment is gone.
If the ophthalmologist diagnoses that the baby has ROP, they will classify the condition according to its severity.
What are the stages of ROP?
To determine how severe ROP is and whether treatment is needed, ophthalmologists classify it into five stages. Stage 1 is the mildest, and stage 5 is the most severe.
- Stages 1 and 2: Mild to moderate ROP. These usually get better without treatment.
- Stage 3: A condition of ROP that may require treatment to prevent damage or detachment of the retina.
- Stage 4: Severe ROP. Part of the retina may have detached. Prompt treatment is essential.
- Stage 5: The most severe form of ROP. The retina may have completely detached. Prompt treatment is essential. Even with treatment, vision loss or blindness can occur.
In addition to these stages, you may hear two more words:
- Aggressive ROP (Aggressive retinopathy of prematurity): This is a type of ROP that becomes severe very quickly.
- Plus disease: This is a severe form of ROP. Here, the blood vessels in the retina are dilated and tortuous.
What are the treatments for ROP?
There are several treatment options for ROP:
- Laser therapy: This treatment involves directing a laser beam at the outer edges of the baby's retina, creating a pattern of small burns. These burns stop the abnormal blood vessels from forming. Laser therapy is about 90% effective in curing ROP.
- Anti-VEGF therapy: This involves injecting a medicine into the baby's eye. This medicine stops the growth of abnormal blood vessels.
Your baby's ophthalmologist will explain the pros and cons of these treatments, and what treatment plan is best for your baby.
Don't worry, doctors are always trying to do what's best for the baby.
If your baby's retina has somehow detached (that is, if ROP is stage 4 or 5), your baby will need further treatment. This is usually done by a retina specialist. For example, your doctor may recommend a surgery called a vitrectomy .
When is ROP treated?
If your baby is at risk of developing a retinal detachment, or if they have already developed a retinal detachment, they will need treatment. Your baby's ophthalmologist will decide the best time for treatment based on the stage of ROP and the information from the tests.
Can ROP be prevented?
ROP is mainly caused by premature birth. Therefore, any steps you can take to reduce the risk of premature birth will also help reduce the chance of your baby developing ROP. It is very important to seek medical advice during pregnancy and follow your doctor's instructions.
But, you should also remember this. Sometimes, even if you do everything you can, you may not be able to prevent a premature birth. If that happens, don't blame yourself for it. Thanks to today's advanced treatments and technology, even premature babies can live healthy, happy lives.
Is ROP going away?
Most of the time, ROP gets better on its own without causing permanent damage to the baby's retina or vision. However, severe cases of ROP require treatment to prevent complications such as retinal detachment and vision loss.
Talk to your baby's ophthalmologist about what kind of treatment your baby will need and how ROP will affect their vision in the future.
How do I take care of my baby?
The most important thing you can do is take your baby to all the screening appointments recommended by your baby's eye doctor. These tests are essential to detect ROP early and begin treatment to reduce the risk of permanent vision damage.
Babies treated for ROP will need follow-up visits throughout their lives. These are especially important in early childhood. During these visits, the baby's eye doctor will check for signs of abnormal blood vessel formation, even years after successful treatment.
Babies who were born prematurely and did not have ROP still need regular eye exams. This is because they are at higher risk of developing certain eye diseases. For example:
- Amblyopia or lazy eye
- Strabismus or crossed eyes
- Glaucoma
Ask your baby's ophthalmologist how often your baby should have eye exams, and follow that schedule exactly.
What questions should you ask your doctor?
To learn more about ROP, you can ask your baby's ophthalmologist questions like these:
- Is my baby at risk of developing ROP?
- How often should my baby be tested for ROP?
- When might my baby need treatment?
- What is the best treatment option?
- What are the advantages and disadvantages of the treatment?
- What follow-up tests will my baby need after treatment?
- What is my baby's outlook?
Finding out that your baby has an eye condition can be a source of anxiety and fear. Learning that your baby has ROP can be stressful, and it can be even more stressful if your baby has other health problems. Remember, your baby's medical team is there to help you every step of the way. Write down your questions and bring them to every appointment. Get all the information you need to support your baby's health during these crucial first few months and beyond.
In summary, take-home message:
Okay, so let's recap the most important points from what we've talked about:
- ROP is a condition that mainly affects the eyes of premature babies.
- Most babies have mild ROP and get better without treatment.
- However, in some severe cases, vision loss can occur, so early detection and treatment are essential.
- Never skip the ROP screenings recommended by doctors. It's the best way to protect your baby's vision.
