Trachoma is a chlamydial infection, while a stye is an infection caused by Staphylococcus aureus.

Trachoma manifests as the formation of trachoma follicles, hyperplasia, and inflammation on the inner surfaces of the eyelid and conjunctiva, with symptoms including redness, swelling, pain in the eyes, neovascularization of the cornea, and vascular pannus. A stye presents with redness, swelling, heat, and pain in the eyelid, mainly caused by inflammation.

In terms of treatment, trachoma mainly uses rifampin eye drops; styes are treated with levofloxacin eye drops, and erythromycin or tobramycin ointment at night, with no hot compresses applied. Typically, a stye can heal within about a week, whereas trachoma requires a longer treatment period, and it is important to rest and undergo regular check-ups.
