Ocular sequelae of preterm birth and their relation to ultrasound evidence of cerebral damage
Insights
Retinopathy of prematurity (ROP) in very preterm infants is linked to brain damage, particularly hypoxic ischemic injury. This eye condition often results in permanent vision problems and refractive errors.
Area of Science:
- Ophthalmology
- Neonatology
- Neurodevelopmental Pediatrics
Background:
- Very preterm infants (born <33 weeks gestation) are at risk for ocular pathologies.
- Retinopathy of prematurity (ROP) and delayed visual maturation (DVM) are significant concerns in this population.
- Long-term neurodevelopmental outcomes are crucial for assessing the impact of prematurity.
Purpose of the Study:
- To investigate the prevalence and types of ocular pathology in very preterm infants.
- To determine the association between ROP and perinatal factors, brain imaging, and neurodevelopmental outcomes.
- To explore the potential link between hypoxic ischemic injury and ROP.
Main Methods:
- Ophthalmic examinations of 177 very preterm infants (born 1979-1982) admitted to NICU.
- Correlation analysis of ROP with perinatal variables, neonatal ultrasound brain scans, and neurodevelopmental assessments.
- Prospective coding of perinatal data and follow-up assessments up to 18 months.
Main Results:
- Ocular pathology was found in 21% of infants; ROP in 8% and DVM in 5%.
- Permanent ocular pathology occurred in 15%, with refractive errors being the most common sequelae.
- ROP was strongly associated with brain damage, suggesting hypoxic ischemic injury, and with shorter gestation and lower birth weight.
Conclusions:
- Hypoxic ischemic damage to the retinal circulation is a potential underlying cause of ROP.
- ROP in very preterm infants is significantly linked to brain injury, highlighting the need for integrated care.
- Early detection and management of ocular conditions in preterm infants are vital for optimal visual and neurodevelopmental outcomes.
Abstract:
The eyes of 177 very preterm (less than 33 weeks' gestation) infants, born between 1979 and 1982 and admitted to a neonatal intensive care unit, were examined as part of an ongoing follow-up study of neurodevelopmental outcome. Ocular pathology was diagnosed in 37 (21%) of the 177 infants: 14 (8%) had retinopathy of prematurity (ROP)--progressive in three--and nine (5%) infants had delayed visual maturation (DVM). The ocular pathology was permanent in 26 (15%) of the 177 infants. Refractive errors were the commonest problem and accounted for permanent sequelae in eight of the 14 infants with ROP and two of the nine with DVM. The presence or absence of ROP was related to a wide range of prospectively coded perinatal variables and to the results of routine neonatal ultrasound brain scans and neurodevelopmental follow-up assessments made in the first 18 months of life. As in previous studies, infants with ROP were of shorter gestation, lower birth weight, and required oxygen therapy for longer than unaffected infants, but the condition was only weakly associated with other indices of respiratory illness. In contrast, ROP was strongly associated with evidence of brain damage, often consistent with hypoxic ischaemic injury. We conclude that an underlying lesion in ROP may be hypoxic ischaemic damage to the retinal circulation.
