What is lacrimal probing?

Lacrimal passage probing is a common surgical method used in ophthalmology. It is mainly used for the diagnosis and treatment of lacrimal passage diseases, such as lacrimal passage stenosis or obstruction in infants or adults, chronic dacryocystitis, etc. According to different functions, it is divided into diagnostic lacrimal passage probing and therapeutic lacrimal passage probing. Diagnostic lacrimal passage probing is mainly used to confirm the upper lacrimal passage, including lacrimal punctum, lacrimal canaliculus and lacrimal sac obstruction. Therefore, it is treated. Therapeutic lacrimal duct probing is mainly used for lacrimal duct obstruction in infants. For adult nasolacrimal duct obstruction, lacrimal duct probing can not play a radical effect. For this situation, RS catheter implantation can be considered during surgery to enhance the effect of surgery and reduce the probability of recurrence of the disease. After surgery, antibiotic eye drops are normally used to control local inflammation.
