When it comes to the anatomy of the eye, most people are familiar with terms like iris, pupil, and eyelid. However, there are lesser-known names for the corners of the eye that are not commonly used in everyday conversation.

One such name for the corner of the eye is the canthus. The canthus refers to the angle where the upper and lower eyelids meet at either side of the eye. There are two canthi on each eye: the lateral canthus, which is on the outer corner of the eye, and the medial canthus, which is on the inner corner of the eye.

Another little-used name for the corner of the eye is the commissure. The commissure is the point where the upper and lower eyelids come together at the outer and inner corners of the eye. Like the canthus, there are two commissures on each eye: the lateral commissure and the medial commissure.

While these terms may not be as commonly known as other parts of the eye, they are important for properly describing the anatomy of the eye and understanding its functions. For example, when discussing the location of a tear duct or the placement of an eyelid lesion, using the terms canthus and commissure can help to provide more precise and accurate information.

Overall, while the names canthus and commissure may not be as frequently used as other terms for the eye, they are still important for anyone interested in learning more about eye anatomy and physiology. By familiarizing yourself with these lesser-known names, you can gain a more comprehensive understanding of how the eye works and how different parts of the eye are interconnected.

So, the next time you're discussing the anatomy of the eye or describing a specific feature of the eye, consider using the terms canthus and commissure to add a level of detail and accuracy to your conversation.
