Abstract:
The computation of eyeball growth has a wide field of applications in orbital and ocular pathology. An anatomic and MRI study to compute eyeball growth has been done. The anatomic study was made to determine the best MRI parameters to calculate the ocular surface; then this surface was computed by MRI in the neuro-ocular plane in fetuses and children aged from 0 to 13 years. The curve of eyeball growth shows rapid growth in utero and until 18 months, followed by a phase of slower growth. This method allows measurement in two dimensions, which we find complementary to ultrasound in the antenatal search for certain congenital malformations.
