[Oculo-orbital anatomy and nuclear magnetic resonance: use in ocular growth and fetal pathology].
The computation of eyeball growth has a wide field of applications in orbital and ocular pathology. An anatomic, macroscopic, histologic and RMI study has correlated the different oculo-orbital signals with the anatomy: a study of compute eyeball growth has been done. The anatomic study was made to determine the best MRI parameters to calculate the ocular surface. The surface was computed by MRI T2 weighted in the neuro-ocular plane in children aged from 0 to 13 years. The curve of eyeball growth shows rapid growth in utero until 18 months and then a phase of slower growth. A second study with fetuses RMI of pregnant women showed the neuro-ocular plane of fetus. Application in antenatal pathology are interesting. Two cases of orbital tumor, with fetal diagnosis are analysed and histologically explained.
