Yellowing of the corners of the eyes may be caused by pigmentation, impaired liver function and blepharospasm. 1. Pigmentation: When patients eat more food containing lutein and carotene in a short period of time, such as spinach, pumpkin, oranges, etc., which are not metabolized by the body in a short period of time, and are deposited in the patient’s body, the yellowing of the corners of the eyes of the patients may be caused, which belongs to normal physiological state, and does not need any special treatment in general. 2. Impaired liver function: After liver function is impaired, the bilirubin metabolism in the human body is abnormal, resulting in increased bilirubin level in the blood, which may trigger jaundice and show yellowing of the corners of the eyes of the patients. 3. Blepharospasm: long-term exposure to ultraviolet sunlight, smoke, welding and other stimuli may induce blepharospasm. Blepharospasm often occurs on the sclera at the corner of the eye toward the cornea, and the color is mostly yellow, but it does not affect vision and may only show yellowing at the corner of the patient’s eyes. When the yellowing of the corners of the eyes is not relieved for a long time or accompanied by discomfort, it is recommended to go to the hospital for relevant examinations so as to avoid delaying the condition.
