Causes of lacrimal sac obstruction
Lacrimal sac obstruction is a common ophthalmic disease, which mainly refers to the failure of normal flow of tears caused by the failure of lacrimal drainage. Tears are secreted by lacrimal glands, which can keep the eyeballs moist, clean the eyes, resist external bacterial infection and other important functions. After the tear is secreted from the lacrimal gland, it needs to flow into the nasal cavity through the lacrimal canaliculus and the lacrimal sac, and then be swallowed into the stomach. When the lacrimal canaliculus or lacrimal sac is blocked, tears cannot flow out, which will cause the lacrimal sac to be blocked.
The reasons for lacrimal sac blockage mainly include two aspects:
First, the anatomical structure of the lacrimal passage was abnormal. The lacrimal passage is composed of lacrimal canaliculus and lacrimal sac, and the connection between them is complex. When the lacrimal passage is poorly developed and special anatomical structures occur, it is easy to cause obstruction of lacrimal drainage.
The second is inflammation and other diseases. For example, eye inflammation such as conjunctivitis and nasosinusitis can cause swelling of the lacrimal passage mucosa, which increases the resistance of tears through the lacrimal passage, and then leads to blockage of the lacrimal sac.
Symptoms of lacrimal sac blockage
The main manifestations of lacrimal sac obstruction are:
1. Repeated cough and runny nose. Tears can not be discharged smoothly from the nasal cavity, which will stimulate the trachea through the mouth nose junction, causing cough and runny nose.
2. Persistent wetting sensation around the eyes. As tears cannot flow normally, there will be a moist feeling around the eyes, which makes people uncomfortable.
3. Frequent conjunctivitis. The blockage of the lacrimal sac makes the tears cannot be discharged, which not only moistens the eye, but also affects the resistance of the eye, and easily leads to recurrent ocular inflammation such as conjunctivitis.
Treatment of lacrimal sac obstruction
For the treatment of lacrimal sac obstruction, Guangzhou Zhongshan Ophthalmology Department provides the following effective measures:
1. Flush with air to dredge the lacrimal passage. By inserting a slender tube into the nasal cavity, use the air pressure to blow through the blocked lacrimal passage, and restore the normal discharge of tears.
2. Flush the lacrimal passage. Use a special instrument to inject clean and sterile physiological saline into the patient's lacrimal passage to flush and clean the blockage.
3. Irrigation and drainage of lacrimal sac. The secretion in the lacrimal sac is aspirated through the sterile syringe and special guide wire to restore the normal drainage of tears.
