Handling the rule of law

It is when the tear drainage system is partially or completely blocked.

Then tears can no longer drain down the nose as usual and will cause live tearing symptoms, irritating or causing chronic eye infections.

The pupil is a tubular system, with a special structure that begins with a scale in the inner corner of the eyelid and ends at the lower nasal slit.

Due to the anatomical feature of the tubular system, the most common pathology in the tears is obstruction. When there is an obstruction, tears are not drained down the nose, so it will flow out. Therefore, the most common symptom is watery eyes. If the obstruction process lasts for a long time, then the tear can build up in the tear duct, which can cause an infection in the tear duct. Religious practice can cause inflammation, pain …, if left for a long time, it will lead to complications in the eye.

Anyone can get sick

Pathology that causes morbidity can be found in all ages, from infants to teenagers, and the elderly. Babies after birth (especially premature babies) can also have a blocked religion, called congenital obstruction. The principle is usually caused by the process of forming the vagina in the fetus is incomplete, so the lower end of the nasal tear duct remains the obstructive membrane. Most of these cases go away on their own as they get older.

The cases of obstruction are often caused by trauma to the eye, sinuses or after surgery in the jaw sinus. Chronic eye infections such as trachoma, conjunctivitis can cause tears narrowed. Religious practice is more common in women than in men.

Common complications

When there is an obstruction, especially an obstruction of the nasal tear duct, it can cause chronic cholecystitis. Patients often have watery eyes, accompanied by purulent discharge. The corner area in the eye can be lighter and tighter. Pressing into this area has pus oozing at the corner of the eye. If left untreated, chronic inflammation can progress to acute inflammation, causing a tear abscess, even leakage, drainage of pus. The patient often aches a lot, the corner in the eye is swollen and red.

The methods of rule of law

Many cases of congenital obstruction will improve on their own within a few months after birth when the baby’s tear drainage system is more complete or when the nasal tear duct opens. In some cases, the ophthalmologist will show you how to press the edge of your baby’s nose to dislodge the membrane.

Most cases of obstruction after a facial injury will not require supportive treatment because the tear drainage system usually takes several months to start working on its own. Therefore, the ophthalmologist will likely suggest the patient wait several months before considering surgery.

In children where the blockage does not improve on its own, or in cases of adults with semi-morbid obstruction, the doctor will intervene with a traditional method. An instrument will be used to dilate the ratio before inserting the catheter into the tear duct through this scale. The stick will be threaded down to the nose and withdrawn. After that, the religion will be pumped with normal saline to flush away the stuffy stagnant substances.

For cases where the vagina is blocked due to inflammation or scar tissue, the doctor will use a small tube thread inserted into the canal down to the nasal tear duct, inflating the balloon at the tip of the tube to expand into a narrow space. , then blow off the ball. This method requires general anesthesia.

Another method, which also requires general anesthesia, is called intubation. The doctor will insert a small piece of the tube into the tear duct through 1 or both of the tear points in the inner corner of the eye, then insert it completely down the nose and remain there for 3 – 4 months. The tip of the tube at the rate is knotted to keep the wire from falling off. This constriction will not cause discomfort.

Surgery is often the option of progressive obstruction. This method is also quite effective for young children with congenital morbidity. However, it is applied after the above methods have failed.

Nasal tear bags are often used to treat most cases of obstruction. The doctor will create a junction between the tear bag and the nose. Therefore, tears will no longer flow down the nasal tear duct, where the obstruction, as before, but flows straight into the nose with a new route. To stabilize the connection, the doctor will put the tube in and save the tube for 3 – 4 months before taking it out.

To prevent postoperative infection, nasal vasoconstrictors and eye drops will be needed. After 3-6 months, the tube placed inside is removed.

If the obstruction is caused by a compression of the tumor, surgery to remove the tumor or other methods to reduce the size of the tumor will be performed to address the cause.
