ixtli (Mdz51r)
This element for ixtli (eye and/or face) has been carved from the compound sign for the place name, Ixcoyamec. It is a full circle with a half of a concentric circle inside and a horizontal line just above the middle of the circle. What would be the eyelid is painted red, the rest is white (except for the black line drawings).

The Nahuatl noun ixtli can refer to eyes or faces, but this visual is clearly evoking an eye. The diphrase "in ixtli in yollotl" ("the eye or face and the heart" served as a metaphor for a person), with what we see and what we feel being essential. This eye will also appear as a star in the sky in some glyphs, which is why some scholars called it a starry eye.
