- PurposeThe purpose was to characterize normal growth patterns of ocular and optical components and to relate them to auxological data in a sample of Swedish children aged 4-15years. MethodsA prospective cross-sectional study was carried out in 143 Swedish children with a mean age of 9.8years. Variables including gestational age (GA), weight, length and head circumference (HCF) at birth and at the time of assessment were registered. Visual acuity (VA), cycloplegic refraction and biometric measures were obtained. Palpebral fissure length and inner canthal distance were measured. Optic disc morphology as seen on fundus photographs was analysed. ResultsChildren born more mature, with male predilection, were found to have deeper anterior and vitreous chamber depths, longer axial lengths and thinner crystalline lens thickness. No correlations were found between ocular biometric measurements and VA or refraction after adjustment for confounding variables. Inner canthal distance was significantly correlated with birth length (p=0.03), height, weight, BMI and HCF (p=0.0008, p=0.0007, p=0.037, and p=0.04, respectively) at time of assessment. Total axial length was found to be significantly correlated with GA (p=0.0226) and length at assessment in girls (p=0.0084). Right optic disc and rim areas decreased with increasing age (p=0.0078 and p=0.0107, respectively); however, optic disc parameters were not dependent on any other variable. ConclusionThese normative values may serve as a basis for the ocular findings and their relationship to auxological data in Caucasian children aged 4-15years, as well as for future comparison in patients with paediatric ocular pathologies.

- PURPOSE: To study ocular morphology and visual function in relation to general growth in moderate-to-late preterm (MLP) children.METHODS: Visual acuity (VA), refraction, optic disc parameters, biometric values and anthropometric measures were obtained from 50 eight-year-old MLP and 43 full-term children. Macular parameters were examined by optical coherence tomography. Serum insulin-like growth factor I (IGF-I) levels were analysed at birth and at assessment and delta IGF-I was calculated.RESULTS: Total macular volume was significantly less in MLP than in controls (both eyes p < 0.01). Macular volume correlated with head circumference (HCF) at assessment [right eye (RE) p = 0.002, r = 0.67; left eyes (LE) p = 0.01, r = 0.54] and refraction (both eyes p < 0.05, r = 0.4) in the MLP children. Furthermore, central retinal thickness correlated significantly with delta IGF-I (RE p = 0.03, r = -0.51, LE p = 0.006, r = -0.59) and refraction (both eyes p < 0.01, r = 0.5) and optic disc areas correlated with weight and height at assessment (all p < 0.05, r = 0.4). Total axial length correlated with HCF at assessment (both eyes p < 0.01, r = 0.5) and VA logMAR (both eyes p < 0.02, r = -0.4).CONCLUSIONS: Macular volume was significantly less in MLP children than in controls examined at 8 years of age. General growth of children and IGF-I levels seem to be involved in development of ocular growth and morphology.
