How to identify lacrimal canaliculus rupture?

Lacrimal canaliculus rupture is a common ophthalmic disease, which can lead to poor tear flow and bring discomfort to patients. In Guangzhou Ophthalmology Department, we often encounter such patients. So, how should we recognize lacrimal canaliculus rupture? Next, I will elaborate from four aspects.

Appearance inspection

One of the obvious symptoms of lacrimal canaliculus rupture is poor tear flow, so visual examination is one of the important methods to identify the disease. When there are wet water marks under the lips, and there are no obvious water marks on the forehead or cheeks, it is likely that the tear canaliculus is broken. In addition, you can also observe whether the patient's eyes have obvious symptoms such as redness, swelling and pain.

If you find yourself or others with the above symptoms, it is recommended that you go to a regular eye hospital for further examination and diagnosis as soon as possible.

Tear discharge test

Tear discharge test is a common diagnostic method. By checking the rate and condition of tear discharge, we can determine whether there is a tear canaliculus fracture. The doctor will drop dye into the patient's eyes and observe whether the dye is discharged smoothly. If the stain cannot be discharged, it indicates that the lacrimal canaliculus may be broken.

However, the lacrimal drainage test is only a preliminary diagnostic method, and further examination such as canaliculography is needed to confirm the canalicular rupture.

Canaliculography

Dacryocystography is an intuitive and accurate examination method, which can clearly show the situation of lacrimal canaliculus. The doctor will inject contrast agent at the entrance of the lacrimal canaliculus, and then use X-ray or other imaging equipment to observe the flow of contrast agent in the lacrimal canaliculus.

If there is obstruction or rupture in one part of the lacrimal canaliculus, the contrast agent cannot pass through smoothly, thus confirming the existence of lacrimal canaliculus rupture.

Examination and diagnosis of ophthalmologist

Finally, the examination and diagnosis of the ophthalmologist is also an important method to confirm the lacrimal canaliculus rupture. The doctor will have a detailed understanding of the patient's medical history, observe the appearance of the eyes, and carry out further examinations according to the patient's symptoms, such as radioactive examination or other auxiliary examinations for the eyes.

Our Guangzhou Ophthalmology Department has experienced ophthalmologists and advanced equipment, which can provide professional examination and diagnostic services for patients.

Summary

Lacrimal canaliculus rupture is a common ophthalmic disease. Through visual inspection, tear discharge test, canaliculography, and the examination and diagnosis of ophthalmologists, we can accurately identify the existence of canalicular fractures. If you have relevant symptoms, it is recommended to seek medical advice in time to obtain professional treatment and help.
