Which eye sign indicates a potential issue with the eyes: yellow or red sclera?

• A. White sclera
• B. Pink conjunctiva
• C. Swollen conjunctiva
• D. Yellow or red sclera

Answer: (D)

The key idea is that the sclera—the white part of the eye—should look white in a healthy eye. When the sclera is yellow, it often signals jaundice from liver or blood problems, meaning bilirubin is building up in the body. When the sclera appears red, it usually points to inflammation, irritation, or a small bleed under the surface, all of which indicate an eye or systemic issue. These color changes are not normal and typically prompt veterinary attention to find the underlying cause. The other signs—white sclera is normal, and pink or swollen conjunctiva reflect surface tissue issues rather than a scleral color change—don’t indicate the same level of concern about the sclera itself. So yellow or red sclera best signals a potential problem.
