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 ...
Orbitomeatal line is a positioning line used in radiography of the skull. [1] It passes through the outer canthus of the eye and the center of the external auditory meatus.It is used for positioning the patient for different radiographic views including Water's view, Perorbital view, Lateral view, and others.
Left gaze: the cornea approaches the electrode near the outer canthus of the left eye, resulting in a negative-trending change in the recorded potential difference. Right gaze: the cornea approaches the electrode near the inner canthus of the left eye, resulting in a positive-trending change in the recorded potential difference.
The accessory visual structures (or adnexa of eye, ocular adnexa, etc.) are the protecting and supporting structures of the eye, including the eyebrow, eyelids, and lacrimal apparatus.
Canthopexy is the surgical fixation of the canthus. A canthoplasty is plastic surgery at the canthus. [8] A canthorrhaphy is suturing of the outer canthus to shorten the palpebral fissure. [8] A canthotomy is the surgical division of the canthus, usually the outer canthus. [8] A lateral canthotomy is the surgical division of the outer canthus ...
The term is used especially in the fields of anatomy and biology. The most common usage of the term refers to the brain's commissures, of which there are at least nine. Such a commissure is a bundle of commissural fibers as a tract that crosses the midline at its level of origin or entry (as opposed to a decussation of fibers that cross obliquely).
