Dacryocystitis
Dacryocystitis is an inflammation of the lacrimal sac, a small pouch located in the inner corner of the eye that collects tears. The lacrimal sac is part of the tear drainage system, and its purpose is to collect tears produced by the lacrimal glands and transport them through the nasolacrimal duct into the nasal cavity. When this drainage system is blocked or infected, it can lead to dacryocystitis.
Here are some details about dacryocystitis:
1. Causes:
- Obstruction: The most common cause of dacryocystitis is a blockage in the nasolacrimal duct, preventing tears from draining properly.
- Infection: Blockage can lead to the accumulation of tears, creating a favorable environment for bacterial growth and infection.
2. Symptoms:
- Redness and swelling in the inner corner of the eye.
- Tenderness and pain around the lacrimal sac.
- Discharge of pus or tears from the affected eye.
- Blurred vision.
- Increased tearing.
3. Types of Dacryocystitis:
- Acute Dacryocystitis: Sudden onset of symptoms, often accompanied by pain and swelling. It can be caused by a bacterial infection.
- Chronic Dacryocystitis: A persistent, long-term inflammation that may be less symptomatic but can lead to recurrent infections.
4. Risk Factors:
- Age: Dacryocystitis is more common in infants and older adults.
- Nasolacrimal Duct Obstruction: Any condition or trauma that causes a blockage in the nasolacrimal duct increases the risk.
- Eye Conditions: Conditions such as conjunctivitis or blepharitis can contribute to dacryocystitis.
5. Diagnosis:
- A thorough clinical examination by an ophthalmologist.
- Irrigation of the tear drainage system to assess blockages.
- Imaging studies, such as dacryocystography, may be used to visualize the anatomy of the tear ducts.
6. Treatment:
-Conservative Measures: Warm compresses, massage of the lacrimal sac, and antibiotic eye drops may be used in mild cases.
- Surgery (Dacryocystorhinostomy - DCR): In cases where there is a persistent or recurrent blockage, surgical intervention may be required to create a new drainage pathway from the lacrimal sac to the nasal cavity.
External Dacryocystorhinostomy (Ex-DCR):
- Procedure: In external DCR, a small incision is made on the side of the nose near the inner corner of the eye. The surgeon then creates a new passageway between the lacrimal sac and the nasal cavity to allow tears to drain properly.
- Recovery: Recovery time varies, but patients can expect some swelling and bruising around the eye after the surgery. The incision site is usually closed with stitches.
Endoscopic Dacryocystorhinostomy (Endo-DCR):
- Procedure: Endoscopic DCR is a minimally invasive procedure that uses an endoscope (a thin, flexible tube with a light and camera) to visualize and access the lacrimal sac and nasolacrimal duct through the nasal cavity. No external incisions are made in this procedure.
- Recovery: Endo-DCR often has a quicker recovery time compared to external DCR. Patients may experience less swelling and bruising, and there is no need for external stitches.
Success Rate:
- Both external and endoscopic DCR have high success rates in relieving symptoms of dacryocystitis and improving tear drainage. The choice between the two procedures often depends on the surgeon's expertise, the patient's anatomy, and the severity of the condition.
Complications:
- Complications of DCR surgeries are rare but can include infection, bleeding, and failure to relieve symptoms. Your surgeon will discuss the potential risks and benefits before the procedure.
Postoperative Care:
- Patients are usually prescribed antibiotics to prevent infection.
- Nasal saline irrigations may be recommended to keep the nasal passages clear.
- Follow-up appointments with the surgeon are essential to monitor healing and address any concerns.

- Recovery: Recovery time varies, but patients can expect some swelling and bruising around the eye after the surgery. The incision site is usually closed with stitches.

Success Rate:
- Both external and endoscopic DCR have high success rates in relieving symptoms of dacryocystitis and improving tear drainage. The choice between the two procedures often depends on the surgeon's expertise, the patient's anatomy, and the severity of the condition.
Complications:
- Complications of DCR surgeries are rare but can include infection, bleeding, and failure to relieve symptoms. Your surgeon will discuss the potential risks and benefits before the procedure.
Postoperative Care:
- Patients are usually prescribed antibiotics to prevent infection.
- Nasal saline irrigations may be recommended to keep the nasal passages clear.
- Follow-up appointments with the surgeon are essential to monitor healing and address any concerns.
7. Prognosis:
- With appropriate treatment, the prognosis for dacryocystitis is generally good.
- Surgical intervention, such as DCR, has a high success rate in relieving symptoms and preventing recurrences.
If you suspect you have dacryocystitis or are experiencing symptoms, it is crucial to consult with an eye care professional for a proper diagnosis and appropriate management. Early intervention can help prevent complications and improve the overall outcome.
