Abstract

Purpose. To investigate the association of birth parameters with refractive status in different age groups of Caucasian children. Materials and Methods. This cross-sectional study included 564 eyes of 282 children aged 4 to 17 years. All children underwent complete ophthalmologic examination. The children were divided into three groups according to their refractive status (emmetropia,myopia, and hyperopia), ages (4–7, 8-9, 10–12, and 13–17), and appropriateness for gestational age, respectively. Results. The mean age of the children was 9.2 ± 2.8 (age range 4–17 years). The mean spheric equivalent was +0.3 ± 1.7 (range: (−10.0)–(+10.0) diopters). The mean birth weight and gestational age were 2681.1 ± 930.8 grams (750–5000 grams) and 37.2 ± 3.7 weeks (25–42 weeks). According to multinominal logistic regression analysis, children with myopia were more likely to have higher birth weights than emmetropic children (OR: 1.0, 95% CI: 1.000–1.001, and P = 0.028). The hypermetropes were found to be significantly small for gestational age between 13 and 17 years of age. Conclusion. Birth weight and appropriateness for gestational age as birth parameters may have an impact on development of all types of refractive errors. The hypermetropic children tended to be small for gestational age.

Highlights

Full term newborn babies tend to be hypermetropic at birth [1, 2] whereas preterm babies have been found to be either hypermetropic or myopic; even very preterm babies with severe ROP are slightly hyperopic at birth [3,4,5].To date, refractive status at birth and its relation to birth weight (BW), birth length, head circumference, and gestational age (GA) have been studied and refractive error has been reported to correlate better with birth weight more than it did with GA [6]
We aimed to investigate the association of birth parameters (BW, GA, and appropriateness for GA) with refractive status in different age groups of Caucasian children
As one of the indicators of intrauterine development, may be associated with several systemic disorders in the long term [18]. Since it affects the eye size, it may have an impact on refractive status or development of refractive error along with gestational age

Summary

Introduction

Refractive status at birth and its relation to birth weight (BW), birth length, head circumference, and gestational age (GA) have been studied and refractive error has been reported to correlate better with birth weight more than it did with GA [6]. Numerous studies have been carried out to find out the relations of refractive error and ocular biometric measures with birth parameters in preterm or low birth weight child at birth and in the long term [6, 9,10,11,12,13]. A few studies investigated the association of birth parameters and refraction or biometric parameters in the general population of children [14,15,16] In this cohort study, we aimed to investigate the association of birth parameters (BW, GA, and appropriateness for GA) with refractive status in different age groups of Caucasian children
