Structures of rim
There are two distinct anatomies to its rim.
- In the common form the rim is “V” shaped, with a groove separating the anterior and posterior parts.
- In the horizontal-oval form there is no groove, and the rim is horizontally oriented and oval in shape, the anterior and posterior parts connected.
