: canthi, palpebral commissures) is either corner of the eye where the upper and lower eyelids meet.

The word canthus is the Latinized form of the Ancient Greek κανθός (kanthós), meaning 'corner of the eye'.

In the Caucasian or double eyelid, the inner corner tends to be exposed completely.

[4] The two canthi of each eye (medial and lateral, that is, inner and outer) are represented in cephalometric analysis by the endocanthion and exocanthion landmarks (single points representing the point of each commissural angle).

Telecanthus, or dystopia canthorum, is a lateral displacement of the inner canthi of the eyes, giving an appearance of a widened nasal bridge.
