What is the term for a yellow deposit noted between the canthus and the edge of the cornea?

The term for a yellow deposit noted between the canthus and the edge of the cornea is known as a pinguecula. This condition is characterized by a small, elevated, yellowish growth that appears on the conjunctiva, commonly seen in individuals who are exposed to sun, wind, and dust. It is typically a benign condition that can occur when the conjunctiva thickens due to irritation or damage from environmental factors, leading to the formation of this deposit.

The presence of a pinguecula is often asymptomatic, but it may cause some irritation or cosmetic concerns. The growth can sometimes be mistaken for other conditions, but its location and appearance help distinguish it.

On the other hand, pterygium is another growth that can occur on the conjunctiva, but it is usually more significant and extends onto the cornea itself, often related to chronic UV exposure. Keratoconus refers to a condition involving a progressive thinning and bulging of the cornea, leading to vision distortion, and is unrelated to the yellow deposits. Arcus senilis is a condition characterized by a gray or white opaque ring in the periphery of the cornea, often associated with aging or hyperlipidemia, rather than a yellow deposit. Thus,
