No significant differences in visual function or ocular morphology were found between children born after intracytoplasmic sperm injection and matched control children at 5 years old, according to a Swedish study.
Margareta Hök Wikstrand and colleagues at Sahlgrenska University Hospital in Mölndal compared visual function and ocular morphology in 137 children born after in vitro fertilization and 159 born after natural conception. The two pediatric groups were matched for age, gender and maternal age.
Of the children conceived via in vitro fertilization, 90.4% had a visual acuity in the better eye of at least 0.8, compared with 93.7% of the children conceived naturally. No significant differences were found between the two groups in terms of hyperopia, myopia, astigmatism, heterotropia, stereoscopic vision and convergence. Goldenhar syndrome, Marcus Gunn syndrome and retinopathy of prematurity were found in one child each in the in vitro group.
The study is published in the January issue of Acta Ophthalmologica Scandinavica.
