Screening-detected refractive errors in infants born after assisted reproductive technology: a prospective cohort study

We observed no increased risk of screening-detected REs at one year of age in ART-conceived infants compared with spontaneously conceived infants, independent of parental infertility diagnoses or specific ART procedures. Among the ART-conceived infants, the use of the GnRH-antagonist protocol may be associated with a lower risk of screening-detected REs; however, this finding should be interpreted cautiously because protocol selection was clinically guided and residual confounding cannot be excluded.
