limbus
Pronunciation: LIM-bus
The junction between the cornea and sclera, serving as a surgical landmark.
Full Definition
The limbus is the anatomical boundary between the clear cornea and the white sclera of the eye. This region contains important stem cells and serves as a crucial surgical landmark for many ophthalmic procedures. In cataract surgery, incisions are often made at or near the limbus. The limbus is also significant in corneal transplantation and refractive surgery planning. Understanding limbal anatomy is essential for proper wound construction and healing.
Usage
Usage note: Critical anatomical landmark referenced in most anterior segment procedures.
