A xanthelasma is a white spot or small yellowish fatty deposit that forms around the inner corners of the upper and lower eyelids. In some cases, it is associated with high cholesterol levels in the bloodstream. So, they are essentially fatty cholesterol deposits around the eyes.
Your eyelid function is not generally affected. But, because xanthelasmas tend to grow, it is better to treat them early. Also, they can be a cosmetic nuisance for many patients.
For most cases, you can get surgical excision to remove sections of the lid’s skin. Also, you could go for Yag laser techniques involving the vaporization of the affected tissue.
