Tear occlusion can occur in the initial part of the excretory system or anywhere in the system.
In adult patients, the most obstructed part is seen in the tubular system between the tear sac and the nose.
It is popularly known as tear vascular occlusion. The most prominent complaint in tear drainage duct is watering.
When the pouch area is pressed, the infected secretion may drain towards the eye.
With channel occlusion, the risk of infection increases. If there is a complaint of redness, swelling and pain at the level of the root of the nose where the tear sac is located, there is an infection.
In this case, it is necessary to give drug treatment before it is too late. Otherwise, the infection may spread to the area where the eye socket is. The patient's vision may be compromised.
Treatment of lacrimal duct obstruction varies according to the site of obstruction of the duct. Specially prepared silicone materials are applied to widen the canal in the obstructions at the entrance of the canal in the eyelids.
These hole-in-the-middle silicone plugs are removed after three months and the canal can be opened in this way. Apart from silicone plugs, tear duct obstructions at the entrance of the canal can be opened with surgery
In cases of obstruction after lacrimal sac, surgery is required. These operations can be performed through the skin (external dacryocystorhinostomy) from the eyelid and the root of the nose, or through the nose (endoscopically) and laser.
Among these methods, the method that is accepted as the gold standard and has the highest surgical success is the external dacryocystorhinostomy surgery performed through the skin.
Endoscopic dacryocystorhinostomy surgery is not suitable for every patient. It is applied according to the examination of the inside of the nose and the determination of the level of duct obstruction.
Its success is not as high as external dacryocystorhinostomy. Surgical success of dacryocystorhinostomy surgery performed by laser is lower than other methods.
The treatment applied in canal occlusion is surgery. The procedure can be done endoscopically via the skin (external) or nasal route.
The success of surgical treatment performed through the skin is over 95% in experienced hands.
