The corneal limbus, also known as the limbus, is a significant component of the human eye. It is a translucent, ring-shaped area located at the junction of the cornea and sclera. The term "limbus" is derived from the Latin word "limbus," which means border. There are several synonyms for this anatomical structure, including corneoscleral junction, corneoscleral limbus, sclerocorneal junction, and sclerocorneal limbus. These terms are often used interchangeably in medical terminology to refer to the same structure. The limbus contains critical structures like stem cells that contribute to the growth and maintenance of the cornea, making it an essential area for ophthalmologists studying the eye.
