Ocular defects in infants of extremely low birth weight and low gestational age

|February 1, 1991
Insights
Very premature infants often experience vision problems. Nearly 60% of high-risk babies studied had eye abnormalities, including blindness from retinopathy of prematurity, highlighting the need for regular eye exams.
Area of Science:
- Ophthalmology
- Neonatology
- Pediatrics
Background:
- Infants born with very low birth weight or extremely preterm are at increased risk for ocular complications.
- Retinopathy of prematurity (ROP) is a significant cause of visual impairment in these vulnerable infants.
Purpose of the Study:
- To assess the long-term ocular health of children born at extremely preterm or with very low birth weight.
- To determine the prevalence and spectrum of ocular abnormalities in a cohort of high-risk infants at age 4.
Main Methods:
- Ophthalmological examinations were conducted on 49 children at 4 years of age.
- Participants included infants born weighing less than 1,000 g or at or before 28 weeks of gestation.
Main Results:
- Twenty-one children (41%) had normal ocular findings.
- Twenty-nine children (59%) exhibited ocular abnormalities, ranging from mild amblyopia to severe visual impairment and blindness due to retinopathy of prematurity.
Conclusions:
- A high proportion of extremely preterm or very low birth weight infants develop significant ocular abnormalities.
- Regular, comprehensive eye examinations are crucial for early detection and management of vision-threatening conditions in high-risk children.
Abstract:
The eyes of 49 babies who weighed less than 1,000 g at birth or who were born at or before 28 weeks gestation were examined at the age of 4 years. Twenty-one children were normal. The remaining 29 children (59%) had ocular abnormalities which ranged from mild amblyopia to blindness from retinopathy of prematurity. The need to examine children at risk is stressed.
