Introduction
Yellow spots on the white part of the eye may be caused by physiological factors, pigmented nevi, hemolytic anemia, or other reasons. The appearance of yellow spots on the sclera could result from various causes. If this condition persists or is accompanied by other serious vision problems, medical attention should be sought promptly, and treatment from a professional ophthalmologist should be received. Meanwhile, regarding the physiological occurrence of yellowish spots...
Yellow spots on the white part of the eye may be caused by physiological factors, pigmented nevi, hemolytic anemia, and other reasons. A detailed analysis is as follows:
1. Physiological Factors
Sometimes yellow spots are not pathological but rather a physiological phenomenon. Normal macular tissue contains carotenoids and flavonoids, which can accumulate in the macular area with age, resulting in a "macular phenomenon" that causes yellow spots on the white of the eye. Generally, this is a harmless physiological occurrence that does not require treatment.
2. Pathological Factors
1) Pigmented Nevus
A pigmented nevus is a localized area of pigmentation formed by melanocytes and other pigment cells, which can also cause yellowish spots on the white of the eye. Pigmented nevi are often genetically inherited, while environmental factors such as sun exposure and hormonal changes may increase the risk. Individuals with yellow skin tones tend to have higher levels of melanin in their skin, making them more prone to developing pigmented nevi and thus more likely to exhibit yellow spots on the sclera. Small pigmented nevi can be treated with laser therapy. After laser treatment, it is important to maintain local hygiene, apply sun protection, and avoid further pigmentation.
2) Hemolytic Anemia
The macula is a crucial part of the retina. In individuals with hemolytic anemia, excessive bilirubin is produced due to the breakdown of hemoglobin and is normally excreted via the liver as bile. However, when there is an overaccumulation of bilirubin or impaired liver function, bilirubin may deposit in the macular region, leading to yellowish discoloration known as macular xanthopsia. Therefore, hemolytic anemia may promote the development of this condition, causing yellow spots on the white of the eye. Under medical supervision, medications such as prednisolone, cyclophosphamide, and azathioprine may be used to alleviate symptoms.
In summary, yellow spots on the white of the eye may result from various causes. If these spots persist or are accompanied by other serious visual problems, prompt medical attention and evaluation by a professional ophthalmologist are recommended. Additionally, for physiologically caused macular discoloration, reducing stress, ensuring adequate sleep and a healthy diet—including foods rich in carotenoids and flavonoids—may help alleviate symptoms.
