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 dilate or explore lacrimal passage.
Abnormal tear position in ectropion: correct ectropion and restore tear. If there is ptosis, it can also shorten ptosis. In addition, electrocautery can also be tried.
Lacrimal canaliculus obstruction: You can try to treat lacrimal duct silicone tube and stay in hospital. In recent years, laser therapy has been used to treat supralacrimal duct obstruction. The light guide fiber is guided to the obstruction by the probe, and the obstruction is opened by the gasification effect of pulsed YAG laser, which can improve the curative effect without intubation or suture after operation.
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 conjunctival sac to lacrimal sac or nasal cavity.
Stenosis of nasolacrimal duct: dacryocystorhinostomy is feasible.
