What to do if the tear sac is blocked? Treatment for blocked tear sac

The eye looks like a very simple sphere, but the inside of the eye is very complex, containing various visual organs and tissues, including lacrimal gland tissue. The lacrimal gland contains lacrimal sacs, which are organs that secrete tears. Tears lubricate the eyeballs, allowing people's eyes to move more easily when taking in the outside world. Lacrimal glands can also have diseases. Among them, lacrimal sac blockage is a common symptom, which can cause dry eyes and tearless eyes. In the long run, it can cause sequelae such as decreased vision and damage to the eyeball. Therefore, lacrimal sac obstruction must not be taken lightly. Let’s take a look at how to treat lacrimal sac obstruction.

Tear duct obstruction is a common ophthalmic disease. It is a disease that occurs at the lacrimal puncta, lacrimal canaliculi, the junction of the lacrimal sac and nasolacrimal duct, and the lower opening of the nasolacrimal duct, with epiphora as the main symptom. If not treated thoroughly, there is a risk of latent intraocular and extraocular infection. The causes of tear duct obstruction include congenital developmental malformations, inflammation, trauma, foreign bodies, tumors and iatrogenic injuries.

Symptoms of lacrimal sac obstruction include epiphora, redness and swelling of the upper eyelid, local swelling, conjunctival congestion, inverted eyelashes, redness and swelling of the lacrimal gland tissue with secretions, etc.

The treatment principle of tear duct obstruction is to control the inflammation of the tear sac and restore or establish the drainage channel from the tear sac to the nasal cavity. Depending on the specific situation of each patient, treatment measures such as nasolacrimal duct probing and catheterization, obstruction incision, artificial tube implantation, lacrimal cystonasal anastomosis, and laser lacrimal ductoplasty can be adopted.

Through the review of the experience of tear duct surgical treatment, the traditional tear duct probing surgery has its limitations. Many complex tear duct obstructions require multiple probing surgeries. Multiple probing surgeries will cause false channels in the tear ducts of children, which means iatrogenic damage to the tear ducts. In the past, no hospital in China was able to perform tear duct intubation surgery, but foreign ophthalmologists used tear duct intubation surgery on almost all children. The introduction of this new technology has brought good news to children with congenital tear duct obstruction in the country. In many clinical cases, tear duct obstruction will recur after a period of probing treatment. The current treatment method is to complete tear duct probing and tear duct intubation at the same time. This treatment is more effective and provides a better opportunity for the reconstruction of the tear duct in children.
