The first is a solid eyelid wart, which is a viral infection that can cause a swelling. It is recommended that you do not squeeze or stimulate the eyelid, as this can lead to infection of the surrounding skin and requires surgery or laser treatment in the hospital. Secondly, if the eyelid is a cystic polyp with a white center, it is considered a fatty granule, which is caused by over-nourishment of the eyelid skin or an abnormal lipid metabolism of the skin, resulting in lipids being wrapped around the epithelial cells, and can be picked out with a needle in the hospital. Thirdly, if there are grains of flesh on the white of the eye, the main consideration may be lid fissures or pterygium, which are white and usually do not invade the cornea. Consider surgical treatment.
