Subjects
In this retrospective cohort study, we examined 133 healthy white children, aged 3–6 years, who visited (with their parents) our clinic for routine eye examinations between January 1, 2011 and March 28, 2013. The investigational purposes of all measurements were explained to parents, after which written informed consents were obtained from both parents of each participating child. The study was approved by the Human Research Ethics Committee of Ondokuz Mayıs University, Samsun, Turkey
Results
Descriptive statistics of all subjects for age; spherical equivalant; central, paracentral, pericentral, and thinnest corneal thicknesses; posterior corneal curvature; total corneal power; central, paracentral, and pericentral axial curvatures; asphericities (anterior and posterior); anterior chamber depth; anterior chamber volume; superior, temporal, inferior, and nasal iridocorneal angles; lens thickness; vitreous length; and axial length are shown in Table 2.

Discussion
During the last trimester of gestation, accelerated fetal weight gain and rapid growth of ocular structures occur. Low birth weight, therefore, may be assumed to be a marker of adverse intrauterine development and growth. It has been shown that both low birth weight and prematurity have important and significant effects on posterior segment structures (eg, fovea, macula, retinal nerve fiber layer, and optic disc).22, 23 In the study, we examined the association between birth weight and anterior

2023, Journal of OptometryCitation Excerpt :Furthermore, other studies reported that ROP contributes to an increase in CCT in newborns independent of prematurity.12 A few studies have evaluated the long-term effects of low BW as a proxy for prematurity on CCT in childhood16 and adolescence17,18 suggesting a decrease in CCT over time. Recently, the Gutenberg Health Study demonstrated in a population-based chohrt that a low BW (<2500 g) is associated with central cornea thinning in adulthood19,20 while less effects were observed on peripheral corneal thickness.20
