Chalazion - Sanryushu (English spelling)
What is the disease? The meibomian glands (sebaceous glands deep inside the eyelids) become clogged. What is the cause?The meibomian glands have openings near the base of the eyelashes, and this condition occurs when these openings become clogged due to inflammation or other reasons. How symptoms manifestA dome-shaped lump appears on the eyelid. It is usually not painful. If left untreated, it will gradually grow larger. When touched from the outside, it feels like a hard lump. If left untreated, the contents may break and leak out from the skin or inside of the eyelid. Testing and diagnosisDiagnosis is relatively easy based on symptoms and the presence of a painless lump. However, if the lesion recurs repeatedly in the same area in elderly patients, it may be cancer, so the tissue removed by surgery must be examined under a microscope. Treatment methodsLocal anesthesia is administered, and the tumor is removed through an incision. In the case of children, general anesthesia is required. In principle, surgery is required, but if surgery is to be avoided, steroid drugs can be injected into the tumor. If this does not cure the tumor, surgery is still required. What to do if you notice an illnessEven if you notice a lump on your eyelid, it usually doesn't hurt, so people tend to delay seeing an ophthalmologist. It tends to get bigger gradually, so it's best to see an ophthalmologist as soon as possible.
