It’s cold and the various signs and symptoms of lacrimal disease are manifesting themselves clearly. Many patients will only seek medical attention, and my personal experience in the practice of medicine is as follows: the patient must be patient and persistent in following medical advice, and the healer must be loving and careful in his work, because we are dealing with flesh and blood. God has given mankind a very fine and wonderful physical body with various functions having real pain sensation. The patient should know that the tear duct contains the tear ducts (water catchers) the lacrimal duct, the common lacrimal duct, the lacrimal sac (pump function), and the nasolacrimal duct (which leads to the nasal cavity), each of which will be blocked and will weep, lose function and will weep, and the nasal cavity will be congested and inflamed and will weep. It shares germs with the nasal cavity and with the conjunctiva, and is prone to inflammation when it is blocked, just as a blocked road pipe will accumulate dirt. If this tube is narrow and easily blocked, regular flushing is necessary, unless your tear ducts are not narrow and drainage is normal and the lower nasal tract is normal, you can rest easy. Note to the doctor: operate gently, follow the path, do not false path, do not rough hands, do not move much, do not not count. Congenital dacryocystitis can be diagnosed by the child’s guardian’s complaint, and then a smooth probe with a rounded head can be used to gently explore the channel at a time, basically 98% success rate. 2% of children with lacrimal duct stenosis and other abnormalities must be placed in the tube support, adult lacrimal ducts are different, almost all must be placed in the tube, regardless of the use of endoscopic ring drill, laser, exploration and other methods are only to guide the tube and different. Of course, it is important for the surgeon to follow the natural duct of the lacrimal duct and operate gently to reduce the repeated non-effective use of the duct, otherwise the duct will be scratched and scarred to aggravate the stricture. Patients after surgery and even surgery when the eye swelling and bruising serious means that patients are prone to bleeding reaction heavy, inappropriate excessive roughness during surgery la, miserable, it is recommended minimally invasive treatment, serious treatment, the patient as a physical heartache point.
