Welcome to week 3

An introduction to week 3 which looks at screening and treatment for sight-threatening ROP.

Screening and treatment for retinopathy of prematurity (ROP) needs to be meticulously coordinated and managed alongside use of agreed clinical criteria for decision making. This week we look closely at all the different components that make up the ROP screening and treatment process and at the selection of the right management pathway.

ROP screening and treatment at the University of Ilorin Teaching Hospital

All preterm babies are registered into a computer on admission to the University of Ilorin Teaching Hospital in Nigeria and those who require ROP screening are identified at this time using a screening guideline poster (shown below). The babies typically have their first eye examination within 30 days of life or before discharge from the NICU if earlier than four weeks after birth.

A specially appointed ROP coordinator ensures these babies are listed and followed up for screening. They post the name of each baby to be screened and their caregivers’ contact details on a calendar. This is reviewed on Tuesdays to confirm the number and location of babies to be screened and ROP screenings are done every Wednesday morning.

The team in the neonatal intensive care unit (NICU) works closely with the ROP team to ensure that:

  • Screening examinations are carried out before discharge from the NICU.
  • Follow up eye exam appointments are made.
  • Caregivers are reminded about ROP screening during follow up appointments with neonatologists.
  • Any babies who miss ROP follow up screening appointments are identified from the calendar and their mothers contacted and encouraged to attend.
  • Any babies who miss ROP screening, either while an inpatient on the neonatal unit or they do not attend after discharge, are identified from the list generated. If they are still an inpatient their names are added to the diary or electronic system for the next screening day; if they have been discharged their mothers are contacted and encouraged to attend.
  • After ROP screening has been completed, parents are given an appointment at 6 months to attend the pediatric ophthalmology department where the baby will be examined to detect other eye complications of prematurity, which are more common in infants who have had ROP. The more frequent complications include strabismus and refractive errors. All infants should be examined again at one year of age, and thereafter if required.

The following case study from the University of Ilorin Teaching Hospital demonstrates the importance of team work and how complex families find the ROP screening and treatment process.

Case study: Baby Abebi

Baby Abebi was delivered at 28 weeks gestational age, with a birth weight of 1.14 kg. In the NICU she required a blood transfusion, nutritional support for poor weight gain and close management for respiratory distress syndrome. She was also provided with supplemental oxygen for 17 days. Abebi’s parents have two other children, both under five years of age, and had to travel into the hospital each day.
Abebi had her first ROP screening in the NICU six weeks after birth. She was found to have type 2 ROP and was discharged from the NICU and the mother was asked to bring her back for further screening a week later. The mother was supported and advised all along. Type 1 ROP in Zone II stage 3 with plus disease was identified in the follow up screening examination when Abebi was 36 weeks and five days old. She was treated using intravitreal bevacizumab and laser and remains on follow up. Abebi’s parents are being given counselling and support and are fully engaged in supporting their daughter’s ongoing needs and development.
