If there is inflammation, anti-inflammatory eye drops or local cold compresses can be used. If there is impingement or foreign body irritation, the impingement needs to be removed or the foreign body needs to be picked out and treated for the cause. If the polyp-like bulge is gradually dipping into the cornea, it is called pterygium. In the early stage, it can be controlled with hormonal eye drops, such as dexamethasone drops, or non-steroidal eye drops, such as diclofenac sodium, but to a certain extent, if it affects the vision, surgery can be considered. If it is caused by acute conjunctivitis, it is usually also accompanied by a significant increase in eye discharge, which needs to be treated with antibiotic eye drops, as well as antibiotic eye ointment.
