Patient's question:
A week ago, due to tearing in the left eye, a left lacrimal canal irrigation was performed, which revealed pus. It improved afterward, but later it was found that her eyes had red bags without tearing or discharge. However, during the follow-up visit, the doctor needed to irrigate both eyes, which resulted in only clean water without pus.Doctor's answer:
There are many treatment methods, but the results are not ideal. For confirmed lacrimal canal obstruction, it is necessary to determine whether the lacrimal sac and nasolacrimal duct are unobstructed to provide targeted treatment. If there is inflammation, the obstruction is likely caused by mucosal swelling. In this case, topical administration of an antibiotic solution with epinephrine should be used first, or irrigation may be performed. If necessary, a probe can be used to dilate the canal, gradually increasing the probe size, which may sometimes be effective. If the obstruction is organic or has already formed scar tissue, and the affected area is small and close to the lacrimal punctum, lacrimal canalotomy can be performed.
