The rate of retinopathy in premature babies is very high, especially leaving visual impairments in premature babies under 28-30 weeks of gestation and babies with birth weight less than 1.5 kg. This is the cause of blindness in children.

1. What is retinopathy of prematurity?

Retinopathy of prematurity (ROP) is a medical condition of the eye caused by abnormal development of retinal blood vessels.
The disease usually occurs in babies born before 31 weeks of pregnancy and weighing less than 1.5 kg. The younger a baby is born, the more likely they are to have retinopathy. This disorder, which usually affects both eyes, is one of the most common causes of long-term vision impairment and blindness in children.
Retinopathy of prematurity has 5 stages:
Stage I: There is a slight growth of abnormal blood vessels; Stage II: There is moderate growth of abnormal blood vessels; Stage III: There is severe growth of abnormal blood vessels; Stage IV: There is severe growth of abnormal blood vessels and partial retinal detachment; Stage V: Total retinal detachment. Retinal conditions in premature babies are divided into two types: mild disease that can heal on its own and severe disease that requires treatment. Most cases of retinopathy of prematurity are mild (accounting for about 90%), the disease improves on its own and has no long-term effects. However, parents still need to take their children to have regular eye exams and follow up regularly to avoid possible complications later on such as strabismus, myopia, glaucoma, delayed retinal detachment,... Therefore Long-term follow-up in a pediatric ophthalmology hospital is necessary for timely detection and intervention.
Severe neonatal retinopathy needs to be treated as soon as possible, otherwise it will cause vision loss, in many cases permanent blindness.

2. When should a premature baby get an eye exam?

Most children with ROP are only brought to the doctor when the disease is severe. Some families, too eager to find the light for their children, have collected all the money to send their children abroad for treatment, but the results are very limited. Because when the nerve has atrophied due to too much damage to the retinal cells, even with surgery abroad with modern means, children still do not have the opportunity to see light.
The rate of ROP according to gestational age is 83% with pregnancy under 28 weeks and 30% with pregnancy over 31 weeks; by weight is 90% for babies born weighing less than 750g and 47% for 1000 - 1250g.
Therefore, doctors recommend, need to appoint ROP examination in all babies with:
Birth weight from 1,500g to 2,000g but suffocated at birth, incubator, prolonged oxygen breathing, other comorbidities and the doctor ordered an eye exam. Birth weight from 1,500g to 2,000g and multiple pregnancies (twins, triplets...). The lower the birth weight or the smaller the gestational age, the higher the risk of ROP. Children who weigh more and have an older gestational age at birth but have risk factors such as respiratory failure, prolonged oxygenation, anemia, infection... also need to have an eye exam. Indicating ROP examination at the 3rd or 4th week after birth is an appropriate time for preterm infants to be screened.

An effective way to prevent retinopathy in premature babies is that pregnant women should manage their pregnancy well to limit premature birth. When being born prematurely, parents must adhere to the eye examination regime for the child, absolutely not be subjective when the baby's eyes appear normal. Many cases of children with ROP have undergone surgery, the fibrous tissue continues to proliferate, causing traction and retinal detachment, so it is necessary to re-examine according to the doctor's orders.

3. Prepare for an eye exam

3.1 Register before the examination date Before the examination, the child will be given a pupil dilator so that the doctor can observe the entire retina, so it is necessary to go to the clinic for an appointment in advance (when you go to register, you do not need to bring the child with you). ) and bring the child to the scheduled date and time.
3.2 Abstain from feeding for at least 1 hour During the examination, the child often cries. To avoid a dangerous (possibly fatal) milk aspiration, the child needs to be fasted from the moment the pupil dilator is instilled.
Bring all necessary papers such as hospital discharge paper, referral for eye exam, antenatal check-up, mother's ultrasound, appointment letter for follow-up examination.
