Answer: Limbal Dermoid

Limbal Dermoids are choristomas which contain epithelium derived tissues. They most commonly occur in the infero-temporal quadrant of the cornea and are localised to superficial layer of cornea and sclera. It can contain tissue for fat, bone, cartilage, skin, teeth muscles, sweat glands, vascular structures or neurological tissues.

Vision can be affected by visual axis encroaching by the lesion, development of astigmatism or infiltration of lipid into cornea.

Surgical excision maybe required for cosmetically unacceptable lesions.
