Yellow sclera

Yellow sclera is a symptom where the whites of the eyes become yellow. It is usually caused by a buildup of bilirubin, a yellow-colored bile pigment. It can develop gradually over time, or it can occur suddenly. It can range from very mild to severe, and can be accompanied by other symptoms such as itching, pain, or redness. In some cases, yellow sclera can be a sign of a more serious underlying condition.
