Lacrimal system diseases (tear ducts)
An idea about lacrimal system diseases and their impact on eye health
What’s a tear duct?
As previously explained, the tear duct or the nasolacrimal duct is the normal drainage pathway of tears in the human eye. This fine channel connects the tear sac (located at the inner corner of the eye near the nose ) to the inner nasal cavity, and
this channel may be completely or partially clogged or obstructed, causing a malfunction in tear drainage.
Symptoms of tear duct obstruction
There are several symptoms of a blocked of the nasolacrimal (tear duct)
- Excessive tears dripping from the eye, or high tear margin appearing on the eye all the time, as if the patient is constantly crying.
- Infections of the eyelids or cornea due to the accumulation and stagnation of unclean unflushed tears loaded with bacteria and germs, which cause repeated discharge and pink eye syndrome.
- Painful swelling of the tear sac located at the inner corner of the eye from the side of the nose.
- Mucous discharge from the eye.
- Bloody tears are contaminated with blood.
It is very important to directly go to your ophthalmologist as soon as these symptoms or some of them appear, because early diagnosis helps making treatment simple, before the problem worsens. In more advanced cases these simple options become impossible or unavailable, and the doctor is forced to surgically intervene to treat the problem.
Nasolacrimal or tear duct obstruction in children
Many children are born with an incomplete tear duct or an imperforated valve at the nasal end of the duct. During the first year of life the tear duct matures and completes its growth. this is a widespread phenomenon, and the obstruction of the tear duct in these cases is not pathological, but just a congenital obstruction that opens automatically with the completion of growth.
In a few cases of congenital duct obstruction, the blockage may not spontaneously open, and your ophthalmologist discusses treatment options with the child’s parents. The first of these options is a regular massage done with proper direction and force to the area adjacent to the nose at the inner corner of the eye mother or father a certain way to massage the area adjacent to the nose underthe eye of the child regularly, to help relieve the block. if this option does not relieve the lock then certain tested are done to correctly diagnose the site and cause blockage. If this blockage is inflammatory and not congenital, then surgical correction of the obstruction (dacryocystorhinostomy) may be used as a last resort.
Nasolacrimal (tear) duct obstruction surgery
Tear duct obstruction surgery dacryocystorhinostomy is used to treat the problem of acquired obstruction or less commonly congenital cases after the failure of other traditional treatment methods,
in children born with congenital occlusion that did not resolve after the completion of the growth or with the manual massage, surgical treatment by slicing the tear duct and
removing the blockage, or by rebuilding a new tear path. The surgery is carried out under the influence of general or local anesthesia depending on the nature of the case and the place of the operation.
