Correct Answer � A Explanation |

A dermoid of the limbus, also known as a limbal dermoid, is a type of benign tumor that occurs at the junction of the cornea and sclera in the eye. It is typically present at birth, although it may not be noticed until later in life. Limbal dermoids are usually located on the nasal side of the limbus and appear as a raised, yellowish-white mass with hair follicles and skin appendages.
Limbal dermoids are thought to arise from a developmental abnormality in which skin cells are trapped in the eye during embryonic development. They are typically unilateral, although they can occur in both eyes in rare cases. Limbal dermoids are usually asymptomatic and do not affect vision, although they can cause irritation and inflammation if they become infected or inflamed.
Diagnosis include visual acuity testing, slit-lamp biomicroscopy, and possibly ultrasound imaging.
Treatment may not be necessary if the dermoid is small and asymptomatic, but larger or symptomatic dermoids may require surgical removal.
In some cases, a limbal dermoid may be associated with other ocular abnormalities, and additional testing or evaluation may be necessary to rule out other underlying conditions.
