Postmortem fetal MRI scans of 58 fetuses (16-42 gestational weeks) were included. Thirty-three fetuses with normal development of optical structures, and 25 fetuses with pathologies were evaluated. Postmortem imaging was performed within 24 hours of fetal demise using a 3T MR scanner and an eightchannel knee coil. T2-weighted axial images and Image J software were utilized to measure total optic nerve length, maximum diameter of optic nerve (retrobulbar and intracranial), angle between optic nerves, and Results
