Diagnostics and treatment of lacrimal duct obstruction in the Ophthalmology Clinic of MC Nairi

Normally, tears flow from the eyes through thin tear ducts, so called lacrimal duct that extend from the eye into the nasal cavity. It is necessary to think about the blockage of the lacrimal canal, when the outflow of tears through the duct is partially or completely disturbed. If the tear duct remains blocked, the lacrimal sac is filled with fluid, swells and inflames, and sometimes becomes infected. Blockage of lacrimal ducts occurs in 6 out of 100 newborns. In adults, blockage of lacrimal ducts occurs much rare and as a result of age-related changes or trauma. The first symptom of lacrimal ducts blockage is a lacrimation of varying degree. Manifestations of blockage of lacrimal ducts may worsen after infectious diseases of the upper respiratory tract, such as the common cold or sinus infections. The reason for the blockage of the lacrimal duct in adults is usually associated with a general disease or trauma. For example, blockage of the lacrimal duct may result from thickening of the tissues lining the lacrimal canal, tissue structure or nasal bone structure disorder or as a complication after surgeries in the nasal region. If infection occurs in the eye's drainage system, redness and swelling around the eyes or nose may be detected. In addition, in the corners of the eyes can accumulate yellowish discharge, and the eyelids can stick each other. In severe cases, the infection can spread to the eyelids and around the eyes. In addition, the symptoms may be more noticeable after exposure to wind, cold and bright sunlight. Diagnosis of lacrimal duct obstruction is based on anamnesis and physical examination. In addition, some tests can be used to measure the number of tears or to determine how normal the outflow of tears from the eyes is. Only in the Ophthalmology Clinic of MC Nairi is carried out a precise localization level and the degree of bstruction of the lacrimal duct by an innovative method called contrast dacryocystography. Methods of treatment If conservative methods of treatment are not effective, then interventional or surgical correction of blocked lacrimal ducts performed: Probing, which is based on the passage of the probe through the obstruction of the lacrimal duct in order to open it. Probing successfully opens the duct in about 90 out of 100 children. In adults, it is less effective. Intubation is placing a silicone tube in the lacrimal duct to create a drainage canal for tears in the nasal cavity. The perforation of the nasal bone in the depth of the nasal cavity in order to create an open canal and increase the passage of the canal into the nasal cavity. Balloon dacryocystoplasty when a miniature balloon attached to the probe is used to open the lacrimal duct. Endoscopic and laser dacryocystorhinostomy. During this procedure, a new lacrimal duct is formed with the help of scopes inserted to the nasal cavity - lighting instruments and a flexible tube with a micro-camera at the top. The type of surgery in lacrimal duct blockage in adults depends on the cause of blockage of the canal and can contain any of the above options.
