What is lateral canthis?

The lateral canthus is the outer corner of the eye where the upper and lower eyelids meet. It is one of the two canthi present in humans, the other being the medial canthus which is the inner corner of the eye. The lateral canthus is formed by the lateral palpebral ligament, the lateral rectus muscle, and the orbital septum.

The lateral canthus plays an important role in the shaping of the eye and the overall appearance of the face. It is often used as a reference point in plastic surgery and facial rejuvenation procedures. In certain cases, abnormalities or laxity of the lateral canthus can cause conditions such as ectropion (outward turning of the eyelid) or entropion (inward turning of the eyelid), which can cause discomfort and vision problems.

In summary, the lateral canthus is an important anatomical feature of the eye and its surrounding structures. Its proper function and appearance are essential for good eye health and facial aesthetics.
