The lacrimal passage will have an effect on the eyes. Some lacrimal passages are blocked and often shed tears. There is something wrong with the eyes, and the eye drops will flow out. You can go and have a look. Should not be expensive.

Lacrimal duct obstruction (or stenosis) means that the initial part of lacrimal duct (lacrimal punctum, canaliculus and lacrimal duct) is narrow and shallow in diameter and communicates with conjunctival sac, and the leader is easily blocked by Hua Tuo's inflammatory trauma. The lower end of nasolacrimal duct is also an anatomically narrow segment, which is easily blocked by nasal lesions.

Lacrimal obstruction is a common and frequently-occurring disease in ophthalmology. If the treatment is not thorough, there is a danger of latent infection inside and outside the eye. Its treatment principle is to control dacryocystitis and restore or establish the lacrimal passage obstruction (or stenosis) from lacrimal sac to nasal cavity drainage channel.

Infants with lacrimal duct obstruction (or stenosis): Try to press the lacrimal sac area with your fingers regularly and use antibiotic eye drops to open the lower end of nasolacrimal duct. Most children can heal themselves after development or stress. If conservative medical treatment fails, all doctors can consider lacrimal passage after half a year. Fermented?

Functional tears overflow: Try eye drops to shrink the lacrimal sac mucosa.

Lacrimal point stenosis, occlusion or absence: lacrimal point dilator can be used to expand or lacrimal probe can be used to explore.

Abnormal position of tears in ectropion: correct ectropion and restore tears. If there is eyelid slack, the eyelid level can be shortened at the same time. In addition, electrocautery can also be tried.

Lacrimal canaliculus obstruction: You can try to treat lacrimal canaliculus obstruction with extremely high silicone tube indwelling. In recent years, laser treatment of lacrimal duct obstruction has been carried out in the morning. The optical fiber is guided to the blocking position by the probe, and the blocking is opened by the gasification effect of pulsed YAG laser. Continue to cooperate with intubation or thread placement can improve the curative effect many times.

Common lacrimal duct obstruction: Conjunctiva-dacryocystorhinostomy can be used, and artificial lacrimal duct can be established with Pyrex tube or its own vein to drain tears directly from conjunctiva sac to dacryocystorhinostomy or to nasal cavity.

Stenosis of nasolacrimal duct: dacryocystorhinostomy is feasible
