What does it mean when the eyeballs turn yellow?

Yellowing of the eyeballs may result from pigment deposition in the bulbar conjunctiva, or it may indicate an underlying disease—such as jaundice. Common types include obstructive jaundice and hemolytic jaundice. Patients should seek medical evaluation at a hospital for proper diagnosis. Prompt treatment is essential upon diagnosis, along with maintaining good ocular hygiene and cleanliness.
