What does it consist of?
The radiologist technician will provide you with a gown and will ask you to remove your clothing and metal objects from the body area where you are going to have the scan. The radiologist will then position you on the X-ray equipment table. Next, the radiologist will locate the lacrimal foramen and insert a flexible tube or fine blunt needle into the lacrimal cavity to administer the liquid contrast medium. In this case, an iodine contrast is used that runs through the lacrimal duct and makes it possible to visualize the entire path of the lacrimal duct, making it possible to determine if there are obstructions or if the duct is permeable.
CASES IN WHICH IT IS RECOMMENDED
Who is it for?
The performance of a dacryocystography is mainly indicated in the case of:
- People who have excessive tearing or a watery eye sensation over a long period of time.
- Patients with recurrent conjunctivitis and painful inflammation of the inner corner of the eye, among other symptoms.
Who is it for?
This test does not require specific prior preparation, but it is important to take into account the following aspects:
- It is important that you come with a clean face, especially the periocular area. Therefore, it is not advisable to wear makeup on the day of the test.
- On the other hand, we will ask you if you suffer from any type of allergy (especially to iodine contrasts or latex) and, in the case of women, if you are pregnant, since in this case the test is contraindicated.
- It is usual to carry out an x-ray prior to the test to assess the state of the paranasal sinuses.
- It is inadvisable to carry out the test if you present signs of infection at that time.
