It is caused by excessive discharge from the eye, especially purulent discharge that sticks to the eyelid and causes inability to open. It is commonly caused by inflammation of the conjunctiva, especially bacterial, resulting in excessive purulent discharge. This is when anti-inflammatory treatment is needed, with anti-inflammatory eye drops, such as tobramycin eye drops, ofloxacin eye drops, pralophine eye drops, erythromycin eye ointment, and diclofenac eye ointment. In the process of treatment, if the eye drops are heavy and affect your life, you can first moisten a sterile cotton swab with anti-inflammatory drops and swab slowly, remembering that you must not use your hands or clothes or toilet paper to wipe, which will aggravate the infection. After the symptoms are reduced by anti-inflammatory treatment, the eye discharge will become less and less, and eventually the discharge will disappear.
