Chalazion

A chalazion is a benign eyelid swelling caused by a blocked oil gland. It typically manifests as a painless, round lump, often on the upper eyelid, initially appearing red and tender before becoming a firm, painless nodule. Meibomian glands, responsible for lubricating the eyes, can become obstructed, leading to the accumulation of thickened oil and subsequent inflammation. While generally resolving on their own over time, chalazia may persist or grow larger, causing discomfort or affecting vision. Initial treatment involves warm compresses and gentle massage to encourage drainage. In cases where these measures are ineffective, medical intervention like steroid injections or surgical drainage may be required for complete resolution.
