A yellow mass in the corner of the eye is a hallmark sign of a pterygium, which is a growth of tissue that starts on the conjunctiva and can extend onto the cornea. This lesion is typically triangular in shape, and it is often influenced by environmental factors, such as UV exposure, wind, and dust. While the growth may initially remain asymptomatic, over time it can become irritated, leading to inflammation and a noticeable yellow or white appearance at its advanced stages.

Other symptoms associated with pterygium may include redness in the eye, which could be indicative of irritation or inflammation. Blurry vision might occur if the pterygium encroaches significantly on the visual axis but is not typically the primary sign. Additionally, dry eyes can occur due to various factors, including environmental conditions, but they are not specifically indicative of a pterygium. Therefore, observing a yellow mass in the corner of the eye is the most direct and characteristic sign of this condition.
