This study investigates the association between self-reported birth weight (BW) and the prevalence of hypertensive retinopathy (HR) in a large population-based cohort in Germany, as part of the Gutenberg Health Study (GHS). The study involved analyzing fundus photographs of 6855 participants, aged 35 to 74, to assess signs of HR, classified according to the Mitchell-Wong Classification. The research aimed to explore the correlation between fetal growth restriction indicated by BW and the frequency of HR. The results showed that the frequency of HR did not significantly differ among groups with different BW ranges. In the univariable analysis, HR was initially associated with high BW, but this association disappeared after adjusting for age, sex, and cardiovascular risk factors. No association was found between low BW and HR. The study reveals novel insights as there are no prior population-based studies specifically exploring this association. [ABSTRACT FROM AUTHOR]

Highlights: What are the main findings? Restricted prenatal growth is associated with increased higher-order aberrations in adulthood. There was an association between increased higher-order aberrations correlating with lower visual acuity and spherical equivalent. What is the implication of the main finding? These results indicate that corneal development is influenced by fetal growth irrespective of prematurity, leading to life-long alterations of ocular shape. Increased corneal aberrations caused by adverse fetal growth might be a risk factor for reduced optical image quality in later life. Background/Aims: This study investigated whether there are changes in corneal surface regularity and corneal thickness in adults born small, appropriate, or large for gestational age at term. Methods: This retrospective cohort study involved prospective Scheimpflug imaging of the cornea (Pentacam®) to compare the corneal thickness and aberrations between adults classified as small for gestational age (SGA), normal birth weight (BW), and large for gestational age (LGA). Multivariable linear regression was applied to analyze associations with gestational age, BW percentile, placental insufficiency, preeclampsia, and breastfeeding. Results: In total, 448 eyes of 261 individuals born full term (aged 29.9 ± 9.5 years, 140 females) were examined, including 29 severe SGA (BW < 3rd percentile), 32 moderate SGA (BW between 3rd and <10th percentile), 132 normal BW (BW between 10th and 90th percentile), 35 moderate LGA (BW between >90th and 97th percentile), and 33 severe LGA (BW > 97th percentile). There were no differences between groups in the corneal aberrations of the total cornea as well as of the corneal front surface, except for higher-order aberrations in the front of the cornea (p = 0.032). There was an association between the increased total root mean square of higher-order aberrations and lower birth weight percentile (p = 0.004), with increased higher-order aberrations correlating with lower visual acuity and spherical equivalent. Conclusion: Restricted prenatal growth is associated with increased higher-order aberrations in adulthood. [ABSTRACT FROM AUTHOR]

GA and BW percentiles were also not associated with CRAE in a multivariable model with adjustment for age, sex, mean arterial blood pressure and arterial hypertension. Preterm birth and associated factors are linked with an increased risk for cardiovascular disease and arterial hypertension in later life (Barker 2004; Barker & Bagby 2005). Associations were assessed with linear regression analyses between GA, BW and BW percentile, ROP occurrence, ROP treatment, placental insufficiency, preeclampsia, breastfeeding, maternal smoking during pregnancy, mean arterial blood pressure (mmHg) and arterial hypertension with retinal vessel characteristics.
