Lacrimal Duct Obstruction (DSR) and Its Treatment

Lacrimal Duct Obstruction (DSR) and Its Treatment

Lacrimal duct obstruction (DSR) causes tearing and discomfort. Treatments include non-surgical methods like warm compresses and medications, as well as surgical procedures like dacryocystorhinostomy (DCR) to create a new drainage pathway.

Consulting an ophthalmologist is crucial for personalized evaluation and treatment, improving eye comfort and quality of life.

What is Lacrimal Duct Obstruction (DSR)?

Tears are an important fluid produced to moisten and protect our eyes. Constantly bathing the surface of the eye, tears also help protect the eyes from infections, irritations, and foreign substances. Tears are produced in our eyes and flow towards the tear ducts between the eye and the eyelids. However, in some cases, the tear ducts can become blocked, leading to a condition known as lacrimal duct system obstruction (DSR).

DSR is typically a congenital condition and is frequently observed in infants, either unilaterally (affecting one eye) or bilaterally (affecting both eyes). Due to a narrowing or blockage in the tear ducts, tears cannot drain normally, resulting in a constant accumulation of tears in the eyes. This condition can cause persistent tearing in infants and sometimes redness of the eyelids.
DSR can also rarely occur in adults. In adults, DSR is often associated with trauma, infection, aging, or as a complication of eye surgery. Blockage in the tear duct can result from structural changes in the eyelid or nasal area.

Lacrimal duct system obstruction usually manifests with noticeable symptoms. These symptoms may include constant tearing in one eye, rarely in both eyes, swelling of the eyelids, redness of the eyes, and occasional recurrent eye infections. Diagnosis of DSR is typically made by an eye doctor. Various tests can be performed to evaluate the function of tear ducts, including tear duct irrigation tests and certain imaging methods.

The treatment of DSR aims to alleviate the symptoms. In infants, DSR often resolves spontaneously, but in some cases, massage and surgical intervention may be required to open the tear duct. In adults, treatment of DSR usually involves surgical intervention, with a success rate of around 90%. Additionally, a procedure called Laser Dacryocystorhinostomy (DCR) can be performed to clear the blockage using laser beams, with a success rate of around 60%. However, the duct may still narrow after the procedure, leading to recurrent blockage. In cases of infection, the infection is treated, and the patient is restored to their previous health. These procedures can be provided at our clinic.

Lacrimal duct system obstruction (DSR) is a condition that affects the tear drainage system and can cause discomfort and complications if left untreated. Therefore, it is important for individuals experiencing constant tearing or other symptoms in their eyes to consult an eye doctor. Your doctor will help determine the appropriate diagnosis and treatment options.

Causes of Lacrimal Duct Obstruction (DSR)

Lacrimal duct obstruction (DSR) is a condition that prevents tears from draining out normally. There can be various causes of DSR, and it often occurs as a congenital condition. Here are some common causes of DSR:

-Congenital Factors: Lacrimal duct obstruction typically occurs during infancy. It can result from incomplete development or failure of the tear ducts to open properly during birth. DSR in infants often resolves spontaneously, but in some cases, treatment may be required.

-Narrowing or Blockage in the Tear Duct: Narrowing or blockage can occur along the lacrimal duct. This constriction or obstruction hinders the normal flow of tears, leading to constant accumulation of tears in the eyes. Narrowing or blockage in the lacrimal duct is often caused by anatomical or structural factors.

-Structural Changes: Structural changes in the eyelids or nasal region can lead to lacrimal duct obstruction. For example, congenital anatomical abnormalities or deformities resulting from trauma can affect the normal functioning of the tear duct.

-Trauma or Infections: The tear duct can be damaged due to trauma or infections. Injuries to the nose or eyelid regions, in particular, can cause obstruction of the tear duct. Additionally, recurrent eye infections can contribute to the blockage of the tear duct.

The causes of DSR can vary, and different factors may be influential in each individual. An eye doctor can assess the individual's condition and determine the specific causes of DSR. Consulting a specialist for accurate diagnosis and treatment is crucial in addressing DSR-related issues.

Symptoms and Diagnosis of Lacrimal Duct Obstruction (DSR)

Lacrimal duct obstruction (DSR) is a condition that typically leads to constant tearing and other symptoms in the eyes. The symptoms of DSR can vary from person to person and the severity may differ. Here are some common symptoms of DSR:

-Constant Tearing: Due to the obstruction in the lacrimal duct, tears cannot drain out normally, resulting in continuous tearing of the eyes. The eyes may appear constantly moist and watery, which is a prominent sign of DSR.

-Swelling of the Eyelids: Persistent moisture in the eyes due to DSR can cause swelling of the eyelids. The eyelids may appear swollen and red, especially more noticeable in the mornings.

-Eye Redness and Irritation: Accumulation of tears can lead to irritation and redness of the eye surface. Itching, a burning sensation, and discomfort in the eyes are also common symptoms.

-Eye Infections: Lacrimal duct obstruction can leave the eyes vulnerable to infections. This can result in recurring eye infections. Symptoms of infection may include redness, tearing, irritation, and eye discharge.

The diagnosis of DSR is typically performed by an eye doctor. The doctor evaluates the patient's symptoms and conducts tests to assess the condition of the lacrimal ducts. These tests may include lacrimal duct irrigation tests, evaluation of tear flow rate, and sometimes imaging techniques. The diagnosis is made based on symptoms, physical examination, and test results.
While the symptoms of DSR may be sufficient for diagnosis, additional tests may be conducted by your doctor as it can sometimes be confused with other eye conditions. Accurate diagnosis is crucial in determining appropriate treatment options, taking into consideration the individual's specific condition.

Treatment Options and Precautions for Lacrimal Duct Obstruction (DSR)

The treatment of nasolacrimal duct obstruction (DSR) aims to alleviate symptoms and regulate tear flow. Treatment options are typically determined based on the severity of symptoms, the patient's age, and the underlying causes of DSR. Here are common options used for DSR treatment:
Surgical Intervention: Surgical intervention is the most commonly used method for treating DSR. This procedure is usually performed under local anesthesia. During surgery, a small incision is made in the area where the blockage occurs, and structural corrections are made to open the tear duct. These corrections may involve widening or reconnecting the duct. Surgical intervention generally has a high success rate and is an effective option for relieving or eliminating symptoms. The success rate is around 90%.

Laser DSR: Laser DSR is a procedure that utilizes laser beams to open a blocked tear duct. During this procedure, a laser probe is inserted into the area where the tear duct is blocked, and laser beams are used to clear the obstruction. Laser DSR is typically performed under local anesthesia and is less invasive compared to surgical intervention. However, the success rate is slightly lower than that of surgical intervention, and in some cases, the duct may become blocked again. The success rate is around 60%.

The choice of treatment method depends on the patient's condition, the severity of symptoms, and other factors. An eye doctor will evaluate the patient's condition and recommend the most suitable treatment option to guide the treatment process.

It is important to take precautions related to DSR. Particularly considering the common occurrence of DSR in infants, preventive measures can be taken. Keeping the baby's eyes clean and hygienic is important to prevent eye infections. Additionally, tilting the baby's head to the side can facilitate tear flow.

Treatment options and preventive measures can vary based on individual conditions and the underlying causes of DSR. Therefore, consulting an eye doctor and having your condition evaluated is the most appropriate step to take.

Managing DSR with early diagnosis and appropriate treatment helps reduce symptoms and prevent complications.
