Description of the Human Eye
- 229 Downloads
Although no organ possesses a strictly geometrical form, it is often useful to describe the adult human eye as a sphere with an average radius of 12 mm completed anteriorly by a transparent portion of a sphere of 8 mm radius. The distance between the centers of these two curvatures is approximately 5 mm. The geometrical axis (axis of a revolution) goes through the anterior and posterior poles of the eye (Fig. 2.1). The equatorial plane crosses the center of the large sphere and is in a plane perpendicular to the geometrical axis. Every plane that passes through the geometrical axis determines a meridional section.
