The inner (sensitive) shell of the eyeball (tunica interna, s. Sensoria bulbi), or the retina, fits snugly from the inside to the choroid along its entire length, from the point of exit of the optic nerve to the edge of the pupil.
Iris is the most anterior part of the choroid, visible through a transparent cornea. It has the form of a disk with a thickness of about 0.4 mm, placed in the frontal plane.
The cornea (cornea) is one of the transparent media of the eye and is devoid of blood vessels. It has the form of a watch glass, convex in front and concave behind. The diameter of the cornea is 12 mm, the thickness is about 1 mm.
The eye (oculus; Greek ophthalmos) consists of the eyeball and the optic nerve with its membranes. The eyeball (bulbus oculi) is round, with poles anterior and polus posterior in it. The anterior pole corresponds to the most prominent point of the cornea, the posterior pole is lateral to the exit point from the eyeball of the optic nerve.
