Three-dimensional FEA model of the eye and orbit with embedded retinal vessels (A) Isometric anterolateral (from the front and side) view of the model with cross section. (B) Anterolateral cross section of the posterior (at the back of the eye) retina (blue) with embedded vessel elements (red). (C) Two-dimensional axisymmetric model derived from the full-scale three-dimensional model. Insert highlights the optic nerve sheath and its contents.
