Implications of the severity of retinopathy of prematurity on childhood development
Insights
Infants with severe retinopathy of prematurity (ROP) show delayed visual development and lower developmental quotients. Long-term monitoring is crucial for these high-risk children.
Area of Science:
- Ophthalmology
- Developmental Pediatrics
- Neuroscience
Background:
- Retinopathy of prematurity (ROP) is a significant cause of visual impairment in premature infants.
- Understanding the long-term developmental impact of ROP severity is crucial for early intervention.
Purpose of the Study:
- To investigate the relationship between the severity of retinopathy of prematurity (ROP) and childhood developmental outcomes.
- To assess visual development using flash visual evoked potential (FVEP) and cognitive development using Developmental Quotient (DQ) and Intelligence Quotient (IQ) tests.
Main Methods:
- Evaluated 21 children (birthweight ≤2500g) with ROP using FVEP (ages 1-3 years).
- Assessed 73 children (birthweight ≤1500g) with ROP using DQ (2.5 years) and IQ (6-7 years).
- Compared outcomes between severe and mild ROP groups.
Main Results:
- Severe ROP group showed significantly longer P100 latency in FVEP compared to mild ROP.
- The main DQ was significantly lower in the severe ROP group (99.1) than in the mild ROP group (108.7).
- Higher proportion of verbal-performance IQ discrepancies in the severe ROP group.
Conclusions:
- Infants with severe ROP are at increased risk for developmental disorders.
- Long-term follow-up and multidisciplinary care involving pediatricians are essential for managing children with ROP.
Abstract:
This study investigated the severity of retinopathy of prematurity (ROP) and its relationship to childhood development. The subjects were 21 children with a birthweight of 2500 g or less who were tested for flash visual evoked potential (FVEP) at conceptual ages ranging from 1 to 3 years. We also examined 73 children with a birthweight of 1500 g or less, using the Developmental Quotient (DQ) test, at 2 1/2 years of age. Twenty-five of this group were given an Intelligence Quotient (IQ) test at 6 to 7 years of age. The P100 latency of FVEP in the severe ROP group was significantly longer than that of the mild ROP group (P < 0.05). The main DQ in the severe ROP group was 99.1 +/- 17.9, significantly lower than the 108.7 +/- 15.5 of the mild ROP group (P < 0.05). No significant IQ differences were found between the two groups. The proportion of children with verbal-performance IQ discrepancies was, however, significantly greater in the severe ROP group than in the mild ROP group (P < 0.05). Since infants with severe ROP are more likely to suffer developmental disorders, long-term follow-up is absolutely necessary and must be done in cooperation with pediatricians.
