Insights
Seven-month-old infants with intrauterine growth retardation (IUGR) show similar vision function to normal birth weight infants. This study found comparable visual acuity and refractive error between the two infant groups.
Area of Science:
- Ophthalmology
- Pediatric Vision
- Developmental Pediatrics
Background:
- Intrauterine growth retardation (IUGR) can impact infant development.
- Vision development is crucial in early infancy.
- Limited data exists on the visual function of infants with IUGR.
Purpose of the Study:
- To compare vision function in 7-month-old infants with IUGR versus normal birth weight infants.
- To assess visual acuity and refractive error in these infant groups.
- To identify potential visual impairments in infants with IUGR.
Main Methods:
- Vision function was measured in 7-month-old infants.
- Two groups were compared: infants with IUGR and infants of normal birth weight.
- Visual acuity and refractive error were assessed, along with the prevalence of anisometropia, astigmatism, and strabismus.
Main Results:
- IUGR infants had an average visual acuity of 6/162 (20/540) and 1.49 D hyperopia.
- Normal birth weight infants had an average visual acuity of 6/118.8 (20/396) and 0.94 D hyperopia.
- Differences in visual acuity and refractive error were not statistically significant between groups. Anisometropia, astigmatism, and strabismus were infrequent in both groups.
Conclusions:
- Infants with IUGR demonstrate visual abilities comparable to those of normal birth weight infants.
- IUGR does not appear to significantly impair early visual development in the studied cohort.
- Further research may explore long-term visual outcomes in IUGR infants.
Abstract:
We measured vision function in a number of 7-month-old infants with intrauterine growth retardation (IUGR) and compared these findings to those for 7-month-old infants of normal birth weight. The IUGR infants had an average visual acuity of 6/162 (20/540) and an average spherical refractive error of 1.49 D hyperopia. The normal birth weight infants had an average visual acuity of 6/118.8 (20/396) and an average spherical refractive error of 0.94 D hyperopia. However, the differences between the infant groups for visual acuity and refractive error were not statistically significant. Anisometropia, astigmatism, and strabismus were infrequent for both infant groups. The results of this study suggest that IUGR infants have visual abilities resembling those of normal birth weight infants.
