Injuries of the lacrimal ducts
Cause Injuries to the tear ducts occur, for example, in bite wounds from dogs or windshield injuries in car accidents. The lacrimal ducts, of which there are two – one on the edge of the upper eyelid and one on the edge of the lower eyelid – are, in the worst case, completely severed and must be restored. Symptoms Due to the injured tear ducts, the tears can only be transported away inadequately.
This results in a dripping of tears. As with any kind of external injury, the risk of infection must be considered. Insufficient hygiene can lead to inflammation, which can quickly become dangerous for the eye.
Therapy The lacrimal ducts are reconstructed. This is done with the help of a silicone tube that is inserted into the tubules and thus maintains the original shape. Now the injured tubules can heal again.
Lacrimal duct stenosis in newborns
In newborns, lacrimal duct stenosis is the most common disease of the lacrimal duct. A stenosis is a narrowing of the tear ducts. Cause In newborns or infants, the exit of the lacrimal duct into the nose may remain blocked.
During the development of the fetus in the womb, a membrane (Hasner membrane) forms in the lacrimal duct, which sometimes remains after birth. SymptomsComplaints The occlusion causes mucus to accumulate and the eye to water. Over time, pus collects in the inner corner of the eye, which then emerges through the tear dots.
Therapy At first, pressure from outside on the lacrimal sac can be used to try to clear the way. If this is not successful, the tear duct is rinsed or, if not successful, probed. If possible, this should not be waited for too long, as there is a risk of sticking. Parents should then observe their newborn well and consult a doctor if they suspect any problems.and lacrimal duct stenosis
