Insights
Very preterm-born children without retinopathy of prematurity show higher risks for decreased visual acuity and anisometropia. These findings highlight the need for continued visual monitoring in this population.
Area of Science:
- Ophthalmology
- Neonatology
- Developmental Pediatrics
Background:
- Very preterm-born (VPB) infants face increased risks for various health complications.
- Retinopathy of prematurity (ROP) is a known risk factor for visual impairment in preterm infants.
- The visual outcomes of VPB children without ROP require further investigation.
Purpose of the Study:
- To compare visual function between very preterm-born (VPB) children with no retinopathy of prematurity (no-ROP) and full-term-born controls.
- To assess visual acuity, color vision, stereoacuity, ocular alignment, refractive errors, amblyopia, and nystagmus.
Main Methods:
- Observational, prospective study of 30 VPB children (born ≤32 weeks gestation) and 30 matched full-term controls.
- Participants aged 6-10 years.
- Comprehensive ophthalmic evaluations were performed.
Main Results:
- VPB children had significantly worse best-corrected visual acuity (BCVA) in their left eyes (P=0.014).
- Higher incidences of myopia, hypermetropia, anisometropia (16.7%), and amblyopia (10%) were observed in VPB children.
- Strabismus occurred equally in both groups (10%).
Conclusions:
- VPB children without ROP are at increased risk for decreased BCVA in at least one eye.
- Anisometropia is more prevalent in VPB children compared to full-term controls.
- These findings emphasize the importance of regular ophthalmic screening for VPB children.
Purpose:
To compare visual dysfunction between very preterm-born (VPB) children with no retinopathy of prematurity (no-ROP) at 6-10 years of age and age- and sex-matched full-term-born controls.
Methods:
This is an observational, prospective study that included 30 children, 6-10 years of age, born ≤ 32 weeks of gestation, with no-ROP, and 30 age- and sex-matched full-term-born controls, conducted from January 2015 until August 2015. All children underwent complete ophthalmic evaluation. Main outcome measures include visual functions (best corrected visual acuity (BCVA), color vision, and stereoacuity), ocular alignment, refractive errors, and the presence of amblyopia and nystagmus.
Results:
Mean BCVA of the right eyes was 0.04 ± 0.08 logMAR for VPB children and 0.02 ± 0.05 logMAR for the full-term children (P = 0.075). Mean BCVA for the left eyes was 0.07 ± 0.09 logMAR for VPB children and 0.02 ± 0.05 logMAR for the full-term children (P = 0.014). Refractive errors were slightly higher though not statistically significant in VPB children compared to full-term children (P = 0.125). The incidence of myopia and hypermetropia was 16.7 and 40%, respectively, in VPB children and 10 and 23.3%, respectively, in full-term children. Anisometropia found only in VPB children with an incidence of 16.7%. Amblyopia found in 10% of VPB children compared to 3.3% in full-term children. Strabismus was found equally in 10% of each group.
Conclusion:
VPB children with no-ROP are at an increased risk of developing decreased BCVA at least in one eye and anisometropia compared to age-matched full-term controls.
