Pus secretions fear blindness Chronic dacryocystitis patients only flow pus but not tears, this is because the initial stage of inflammation did not completely block the tear duct, so the patient does not have symptoms of tear overflow, and the pus did not overflow, pus did not overflow does not mean that the tear sac is not inflamed, it may just be a relatively mild inflammation, but once found to have pus overflow, it means that the inflammation has been more serious, and the tear sac filled with inflammation has become the eye The “invisible threat”. The inflammatory phase of the tear sacs need to be timely medical treatment The early stage of the tear sacs are easily ignored, many people will be mistaken for the fire caused by the increase in eye droppings, thus delaying treatment, until the acute onset of the period to think about medical treatment, the most appropriate treatment at this time is to immediately undergo nasal endoscopic surgery, only under the nasal endoscope, in order to clearly see the inflammatory situation within the tear sacs, so as to take targeted treatment, in the tear sacs and It is also a new tear duct between the nasal cavity and the nasal endoscope, and the lacrimal sac is perforated with medication directly on the affected area to reduce inflammation, so that the inflammation will gradually subside and the tear duct will not become inflamed easily after it is opened.
