The canthus (pl.: canthi, palpebral commissures) is either corner of the eye where the upper and lower eyelids meet.[1] More specifically, the inner and outer canthi are, respectively, the medial and lateral ends/angles of the palpebral fissure.
The bicanthal plane is the transversal plane linking both canthi and defines the upper boundary of the midface.
