Canthus (pl. canthi, palpebral commissures) is either corner of the eye where the upper and lower eyelids meet.[1] More specifically, the medial and lateral canthi would be described as 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.

Commissures
- The lateral palpebral commissure (commissura palpebrarum lateralis; external canthus) is more acute than the medial, and the eyelids here lie in close contact with the bulb of the eye.
- The medial palpebral commissure (commissura palpebrarum medialis; internal canthus) is prolonged for a short distance toward the nose, and the two eyelids are separated by a triangular space, the lacus lacrimalis.
Surgery
Canthoplasty refers to a plastic surgery of the medial and/or lateral canthus.
A canthotomy involves cutting the canthus, often performed to release excessive orbital pressure (i.e., from orbital hemorrhage or infection).
Pathology
"Dystopia canthorum" is associated with Waardenburg syndrome.[2]
