Why Are My Eyes Red?
5. Chalazion and Stye
Chalazion refers to a cyst in the eyelid due to the blockage of an oil gland. Patients generally present with a painless swelling on the eyelid and redness that progresses over a few weeks. There may also be heaviness of the eyelid, redness of the conjunctiva, and increased tearing. It is not due to an infection. It may be confused with a stye as it appears to be similar.
However, a stye is often painful with the bump located on the edge of the eyelid and occurs due to a bacterial infection by Staphylococcus aureus. Both these conditions causes redness on the affected eyelid. Treatment involves the application of a warm compress. A large chalazion may require incision and drainage. A stye may require antibiotic ointment. Both conditions are usually harmless and resolve with time.
