lacrimal caruncle
whitish oily secretion that occurs during sleep
The lacrimal caruncle is a small, fleshy, triangular-shaped structure located in the inner corner of the eye, where the upper and lower eyelids meet. It is also called the caruncula lachrymalis.
The lacrimal caruncle contains sebaceous and sweat glands, as well as accessory lacrimal glands. It is also rich in blood vessels, which can make it appear red or pink in color.
The lacrimal caruncle plays a minor role in the production of tears, but it does contribute to the lubrication of the eye by producing a small amount of fluid. It also acts as a barrier between the eye and the external environment to help prevent foreign particles and debris from entering the eye.
In some cases, the lacrimal caruncle can become inflamed or irritated, causing it to become red, swollen, and painful. This condition is known as carunculitis, and it can be treated with topical or oral antibiotics or anti-inflammatory medications, or in severe cases, surgical removal may be necessary.
