Screening of Septo-optic Dysplasia During a Fetal Examination at 16-20 Weeks of Gestation

Plain-language summary

Evaluation of prenatal optic chiasm (OC) is important for the differential diagnosis of septo-optic dysplasia (SOD), which is a congenital optic disc anomaly, and the absence of the cavum septum pellucidum (CSP). Septo-optic dysplasia is associated with a wide range of neurological abnormalities, including hypoplasia of the visual pathways, CSP agenesis, and developmental delay.
