Limbal nodule
Limbal Nodule
Limbal Nodule (/ˈlɪmbəl ˈnɒdjuːl/) is a medical term referring to a small, rounded mass or growth that appears at the limbus of the eye. The limbus is the border between the cornea and the sclera, the white part of the eye.
Etymology
The term "limbal" is derived from the Latin word "limbus", meaning "border" or "edge", and "nodule" comes from the Latin "nodulus", a diminutive of "nodus", meaning "knot". Thus, a limbal nodule is essentially a "small knot at the edge".
Related Terms
- Cornea: The clear front surface of the eye, which covers the iris and pupil.
- Sclera: The white outer layer of the eye, continuous with the cornea at the limbus.
- Limbus: The border or transitional zone between the cornea and the sclera.
- Nodule: A small, rounded mass or growth that is solid to the touch.
Diagnosis and Treatment
Diagnosis of a limbal nodule typically involves a thorough eye examination by an ophthalmologist. The nodule may be biopsied to rule out malignancy. Treatment depends on the underlying cause of the nodule. In some cases, no treatment may be necessary, while in others, surgical removal or medication may be recommended.
