Pus in the eye is usually caused by inflammation due to infection of the local skin, mucous membrane and other tissues of the eye by disease-causing bacteria, so the treatment of this disease is based on anti-infective treatment. If it is an ocular surface disease, such as granuloma or conjunctivitis, you can keep the local area of the eye clean and use antibiotic eye drops to control the inflammation, such as levofloxacin hydrochloride eye drops and tobramycin eye drops. In case of corneal inflammation or inflammation inside the eye, it is trickier to deal with as it can affect vision. This condition must be taken seriously and antibiotic medication should be chosen early to control the inflammation. Systemic application of antibiotics can also be considered when symptoms are more pronounced. Only when the inflammation is normalized as soon as possible, the local purulent discharge will decrease and the inflammation will return to normal. After the appearance of this situation, it is necessary to go to the hospital as soon as possible to carry out relevant examinations, to clarify the specific conditions and then early treatment.
