Chronic dacryocystitis

Introduction to chronic dacryocystitis Chronic dacryocystitis is the most common form of lacrimal sac lesions. After secondary stenosis or obstruction of the nasolacrimal duct, tears are retained in the lacrimal sac, accompanied by bacterial infection. The main cause of this disease and mucinous cystic cystic disease. Identification, is a certain degree of diffuse hyperemia for the skin of the lacrimal sac, conjunctivitis and tears are more obvious. Severe cases can form a purulent cyst. This is a relatively common eye disease that occurs in middle-aged and older women and is more common in rural and remote areas. Common in trachoma, lacrimal trauma, rhinitis, nasal septum deviation, nasal polyps, lower turbinate hypertrophy and other obstructive nasal lacrimal passages, tears can not be discharged, long-term retention in the lacrimal sac. Symptoms such as tears, mucus or purulent secretions flowing out of the tears. basic knowledge Sickness ratio: 0.1% Susceptible people: no special people Mode of infection: non-infectious Complications: keratitis, purulent corneal ulcer

Causes of chronic dacryocystitis

Cause:

Due to obstruction or stenosis of the nasolacrimal duct, it is common in trachoma, lacrimal duct trauma, rhinitis, nasal septum deviation, nasal polyps, inferior turbinate hypertrophy, etc., blocking the nasal lacrimal passage, tears can not be discharged, long-term retention in the lacrimal sac, tears Bacteria, such as pneumococci, staphylococcus, etc., breed here, irritating the lacrimal sac wall, causing chronic inflammation of the lacrimal sac mucosa, producing mucous or purulent secretions.

Chronic dacryocystitis prevention

Pay attention to eye hygiene, check the eyes regularly to prevent poisonous evils from getting deep or repeated.

For patients with severe sore scurvy, tears and patients undergoing eye surgery should pay attention to check whether the disease is present, so that early detection and timely treatment.

Avoid eating pungent foods such as spicy sputum, especially those suffering from eye diseases, but also need to pay attention to avoid the accumulation of damp heat in the spleen and stomach, causing eye diseases.

Timely and thorough treatment of trachoma, blepharitis and other external eye inflammation, do not give the bacteria a chance.

Patients with nasal septum deviation, lower turbinate hypertrophy or chronic rhinitis should be treated as soon as possible.

Chronic dacryocyst complications Complications keratitis claudication corneal ulcer

Long-term chronic dacryocystitis is a serious threat to the safety of the eye, such as corneal infection, Portuguese corneal ulcer or eye penetrating injury, internal eye surgery, etc. can cause full ocular inflammation, and loss of visual function .

Chronic symptoms of chronic lacrimal sacitis Common symptoms Conjunctival hyperemia, tears in the elderly, excessive sputum, conjunctival congestion, exposure... Eating tears and purulent secretions

(A) tears, conjunctival congestion in the internal iliac crest, skin often has eczema.

(B) Squeeze the lacrimal sac with the fingers, and there is mucus or mucopurulent secretions flowing out from the small tears.

(3) Due to the massive accumulation of secretions, the lacrimal sac gradually expands and a saclike bulge is formed below the medial malleolus ligament.

Chronic dacryocystitis

Except for the tears, there are no other symptoms. Only when the lacrimal sac is flushed, the secretions can be seen to flow backwards.

Because mucus purulent secretions are refluxed into the conjunctival sac for a long time, and the corneal epithelium is damaged, the bacteria in the secretion can cause infection, causing corneal ulcers. If there is a perforation of the eyeball or surgery for the inner eye, it will also cause eyeballs. infection.

Diagnosis and identification of chronic dacryocystitis

1. The sebaceous gland cyst is superficial and generally has no fistula.

2. Cold abscess: combined with x-ray photos and detailed medical history, you can confirm the diagnosis.
