What is lateral.canthus?

The lateral canthus refers to the outer corner of the eye where the upper and lower eyelids meet. It is also known as the outer canthus or outer commissure. The lateral canthus plays an important role in defining the shape and appearance of the eye, and it is also involved in the drainage of tears from the eyes. It is formed by the articulation of the orbital bones and the surrounding muscles and ligaments. In some cases, the lateral canthus may require surgery to correct a droopy or sagging appearance, or to repair damage caused by trauma or injury.
