Stenosis of the lacrimal canaliculi refers to a condition where the tear ducts that drain tears from the eyes to the nose become narrowed or blocked. This blockage can lead to excessive tearing, discomfort and even infections.
The lacrimal canaliculi are small channels located on the inner corner of the eye that collect tears. These tears then drain through the lacrimal sac and into the nose. In cases of stenosis, the tears are unable to drain properly and can cause irritation, inflammation, and even infections.
The most common cause of stenosis of the lacrimal canaliculi is age-related changes in the tear ducts. As we age, the tissues in our body become less elastic, and the tear ducts can become narrower, leading to blockages.
In addition to age, other factors that can cause stenosis of the lacrimal canaliculi include trauma to the eye area, infections, tumors, and certain medical conditions such as sarcoidosis or Wegner's granulomatosis.
The most common symptom of stenosis of the lacrimal canaliculi is excessive tearing. This can occur when the tears are unable to drain properly, causing them to overflow onto the face. Other symptoms may include eye redness, irritation, swelling, and discharge.
The treatment for stenosis of the lacrimal canaliculi depends on the severity of the condition. Mild cases may be treated with warm compresses to help open the tear ducts. In more severe cases, surgery may be necessary to remove the blockage and allow the tears to drain properly.
