Difference between wheals and chalazion

  Macrophthalmia is an acute purulent inflammation of the eyelid glands. It is also known as “blepharitis” and “pinhole”. It is treated mainly with antimicrobial eye drops. In some children, the inflammation gradually subsides and heals; in others, it turns into an abscess, which typically manifests itself as a decreasing peripheral congestion, limited inflammation, and a fluctuating sensation under the skin. The abscess may break down on its own, or the skin may be cut open to drain the abscess, leaving a scar.  Chalazion is a chronic granulomatous inflammation of the eyelid glands. The cause is primarily a chronic inflammation of the sebaceous glands due to their high secretion and poor exclusion; it can also result from long-term recurrent episodes of wheals. Some of them grow inside the eyelids and are more hidden, and the masses are found only when they are larger; some grow on the skin surface and leave scarring easily. For smaller masses, antimicrobial eye drops can be used for a short period of time, but if the mass cannot be absorbed or even grows gradually, it should be surgically removed.
