A chalazion is a lump from a blocked Meibomian glands, oil producing glands in the eyelid that help to form the tear film.
The first measures to treat chalazion are conservative: warm compresses and Ophtamologist visit to assess the need of antibiotic therapy and full eye examination.
When chronic, the cyst can be surgically removed. While some chalazion can be removed with loca anesthesia in very cooperant patients, sedation or general anesthesia helps to avoid blinking, ensuring a safer and faster procedure.
Do not let such lesions without medical survaillance, because, some premalignant or even malignant lesion can have similar appareances to chalazion, and require a different course of treatment.
