In this study, we investigate if children born following assisted reproduction technologies (ARTs) are at an increased risk for long-term ophthalmic complications. For this purpose, a population-based cohort analysis was conducted which included all deliveries between 1991 and 2014 at a single tertiary medical center. Offspring were classified relative to conception method as ART or spontaneous pregnancies. Offspring hospitalizations up to the age of 18 years involving ophthalmic morbidities were evaluated according to a predefined set of ICD-9 codes. A Kaplan–Meier survival curve was used to compare cumulative hospitalization rates in exposed (ART) and unexposed offspring (spontaneous), and a Cox proportional hazards model was used to control for potential confounders. A total of 243,682 deliveries were included in the study. In that, 1.8% of the deliveries (4364) were of mothers who underwent fertility treatments and 98.2% (239,318) were conceived spontaneously. Offspring born to mothers who underwent fertility treatments had a significantly higher hospitalization rate involving ophthalmic morbidity, as compared to spontaneously conceived offspring (1.2% vs. 1.0%, p = 0.04). The Kaplan–Meier survival curve pointed to a significantly higher cumulative incidence of ophthalmic morbidity following ART (log rank p = 0.02). Cox proportional hazards model was adjusted for maternal age, preterm delivery, maternal hypertensive disorders, diabetes, and mode of delivery which demonstrated ART as an independent risk factor for long-term pediatric ophthalmic morbidity (adjusted hazard ratio = 1.37, CI 1.04–1.80, p-value = 0.02). We concluded that ART is an independent risk factor for long-term ophthalmic morbidity of the offspring. [ABSTRACT FROM AUTHOR]

Objectives: To assess the prevalence of corneal astigmatism among patients before routine cataract surgery and overall ocular difference between Jewish and Bedouin population in the south of Israel., Methods: Retrospective research collecting biometric information from IOLMaster (Carl Zeiss Meditec AG, Germany) in patients attending cataract surgery at Soroka University Medical Center, Beer-Sheva, Israel between the years 2015 -2016., Results: Mean corneal astigmatism among all cohorts was 1.20D ± 0.83, with 1.26D ± 0.84 in Bedouins patients vs 1.17D ± 0.82 in Jews patients (p-value=0.08). Corneal astigmatism lower than 0.5D was seen in 20% of the population, 28% of the population had corneal astigmatism above 1.5D and 9% showed corneal astigmatism higher than 2.5D. When comparing axial length and keratometric characteristics between the two populations, Bedouins had shorter axial length (23.41mm± 1.62 vs. 23.67mm ± 1.55, p=0.01), and flatter corneas on both axes (flat - 43.18D ± 1.76 vs. 43.62D ± 1.79, p<0.01); (steep - 44.44D ± 1.84 vs. 44.77D± 1.89, p<0.01). Higher astigmatism was found in men than in women (1.24D vs.1.15D p- value=0.04) of study group., Conclusions: In our study we found more than 25% of patients had astigmatism more than 1.5D. Patients attending cataract surgery may therefore benefit the use of advanced IOL types and surgical techniques. In addition, a statistically significant difference between the Bedouin and Jewish populations biometric measurements in patients attending cataract surgery found.
